Emperors in the West

Organization of the Empire

Economically, socially, and militarily, Turkey was a medieval state, unaffected by the developments in the rest of Europe. Turkish domination over the northern part of Africa (except Tripoli and Egypt) was never well defined or effective, and the eastern border was inconstant, shifting according to frequent wars with Persia. Of the vassal princes, only the khans of Crimea were generally loyal.

The sultans themselves had sunk into indolence and depravity. Until the ascension (1603) of Ahmad I, the succession to the throne was habitually contested by all the sons of the deceased sultan, and it was the patriotic duty of the victor to kill his rivals in order to restore order. Although this practice was barbarous, when it ceased other problems arose. The eldest male member of the family was recognized as the heir-designate, but to prevent threats to the sultan the imperial prince was denied any involvement in public affairs and was kept in luxurious imprisonment. When the prince finally ascended the throne, he was often alcoholic or lunatic.

Actual rule was usually exercised by the grand viziers, many of whom were able men (notably those of the Köprülü family). The sultans themselves often were the creatures of the Janissaries, whose favor was purchased by large gifts at the ascension of a sultan.

One of the most nefarious aspects of the court of Constantinople (known as the Seraglio and the Sublime Porte) was the all-pervading corruption and bribery that had been raised to a system of administration. The pashas and hospodars (governors) who administered the provinces and vassal states purchased their posts at exorbitant prices. They recovered their fortunes by extorting still larger sums from their subjects. The peasantry was thus reduced to abject misery.

A positive feature in Ottoman administration was the religious toleration generally extended to all non-Muslims. This, however, did not prevent occasional massacres and discriminatory fiscal practices. In Constantinople the Greeks and Armenians held a privileged status and were very influential in commerce and politics. The despotic system of government was mitigated only by the observance of Muslim law.

History

The Ottoman state began as one of many small Turkish states that emerged in Asia Minor during the breakdown of the empire of the Seljuk Turks. The Ottoman Turks began to absorb the other states, and during the reign (1451-81) of Muhammad II they ended all other local Turkish dynasties. The early phase of Ottoman expansion took place under Osman I, Orkhan, Murad I, and Beyazid I at the expense of the Byzantine Empire, Bulgaria, and Serbia. Bursa fell in 1326 and Adrianople (the modern Edirne) in 1361; each in turn became the capital of the empire. The great Ottoman victories of Kosovo Field (1389) and Nikopol (1396) placed large parts of the Balkan Peninsula under Ottoman rule and awakened Europe to the Ottoman danger. The Ottoman siege of Constantinople was lifted at the appearance of Timur, who defeated and captured Beyazid in 1402. The Ottomans, however, soon rallied.

The empire, reunited by Muhammad I, expanded victoriously under Muhammad's successors Murad II and Muhammad II. The victory (1444) at Varna over a crusading army led by Ladislaus III of Poland was followed in 1453 by the capture of Constantinople. Within a century the Ottomans had changed from a nomadic horde to the heirs of the most ancient surviving empire of Europe. Their success was due partly to the weakness and disunity of their adversaries, partly to their excellent and far superior military organization. Their army comprised numerous Christians—not only conscripts, who were organized as the corps of Janissaries, but also volunteers. Turkish expansion reached its peak in the 16th cent. under Selim I and Sulayman I (Sulayman the Magnificent).

The Hungarian defeat (1526) at Mohács prepared the way for the capture (1541) of Buda and the absorption of the major part of Hungary by the Ottoman Empire; Transylvania became a tributary principality, as did Walachia and Moldavia. The Asian borders of the empire were pushed deep into Persia and Arabia. Selim I defeated the Mamluks of Egypt and Syria, took Cairo in 1517, and assumed the succession to the caliphate. Algiers was taken in 1518, and Mediterranean commerce was threatened by corsairs, such as Barbarossa, who sailed under Turkish auspices. Most of the Venetian and other Latin possessions in Greece also fell to the sultans.

During the reign of Sulayman I began (1535) the traditional friendship between France and Turkey, directed against Hapsburg Austria and Spain. Sulayman reorganized the Turkish judicial system, and his reign saw the flowering of Turkish literature, art, and architecture. In practice the prerogatives of the sultan were limited by the spirit of Muslim canonical law (sharia), and he usually shared his authority with the chief preserver (sheyhülislam) of the sharia and with the grand vizier (chief executive officer).

In the progressive decay that followed Sulayman's death, the clergy (ulema) and the Janissaries gained power and exercised a profound, corrupting influence. The first serious blow by Europe to the empire was the naval defeat of Lepanto (1571; see Lepanto, battle of), inflicted on the fleet of Selim II by the Spanish and Venetians under John of Austria. However, Murad IV in the 17th cent. temporarily restored Turkish military prestige by his victory (1638) over Persia. Crete was conquered from Venice, and in 1683 a huge Turkish army under Grand Vizier Kara Mustafa surrounded Vienna. The relief of Vienna by John III of Poland and the subsequent campaigns of Charles V of Lorraine, Louis of Baden, and Eugene of Savoy ended in negotiations in 1699 (see Karlowitz, Treaty of), which cost Turkey Hungary and other territories.

The breakup of the state gained impetus with the Russo-Turkish Wars in the 18th cent. Egypt was only temporarily lost to Napoleon's army, but the Greek War of Independence and its sequels, the Russo-Turkish War of 1828-29 (see Adrianople, Treaty of), and the war with Muhammad Ali of Egypt resulted in the loss of Greece and Egypt, the protectorate of Russia over Moldavia and Walachia, and the semi-independence of Serbia. Drastic reforms were introduced in the late 18th and early 19th cent. by Selim III and Mahmud II, but they came too late. By the 19th cent. Turkey was known as the Sick Man of Europe.

Through a series of treaties of capitulation from the 16th to the 18th cent. the Ottoman Empire gradually lost its economic independence. Although Turkey was theoretically among the victors in the Crimean War, it emerged from the war economically exhausted. The Congress of Paris (1856) recognized the independence and integrity of the Ottoman Empire, but this event marked the confirmation of the empire's dependency rather than of its rights as a European power.

The rebellion (1875) of Bosnia and Herzegovina precipitated the Russo-Turkish War of 1877-78, in which Turkey was defeated despite its surprisingly vigorous stand. Romania (i.e., Walachia and Moldavia), Serbia, and Montenegro were declared fully independent, and Bosnia and Herzegovina passed under Austrian administration. Bulgaria, made a virtually independent principality, annexed (1885) Eastern Rumelia with impunity.

Sultan Abd al-Majid, who in 1839 issued a decree containing an important body of civil reforms, was followed (1861) by Abd al-Aziz, whose reign witnessed the rise of the liberal party. Its leader, Midhat Pasha, succeeded in deposing (1876) Abd al-Aziz. Abd al-Hamid II acceded (1876) after the brief reign of Murad V. A liberal constitution was framed by Midhat, and the first Turkish parliament opened in 1877, but the sultan soon dismissed it and began a rule of personal despotism. The Armenian massacres (see Armenia) of the late 19th cent. turned world public opinion against Turkey. Abd al-Hamid was victorious in the Greco-Turkish war of 1897, but Crete, which had been the issue, was ultimately gained by Greece.

In 1908 the Young Turk movement, a reformist and strongly nationalist group, with many adherents in the army, forced the restoration of the constitution of 1876, and in 1909 the parliament deposed the sultan and put Muhammad V on the throne. In the two successive Balkan Wars (1912-13), Turkey lost nearly its entire territory in Europe to Bulgaria, Serbia, Greece, and newly independent Albania. The nationalism of the Young Turks, whose leader Enver Pasha gained virtual dictatorial power by a coup in 1913, antagonized the remaining minorities in the empire.

The outbreak of World War I found Turkey lined up with the Central Powers. Although Turkish troops succeeded against the Allies in the Gallipoli campaign (1915), Arabia rose against Turkish rule, and British forces occupied (1917) Baghdad and Jerusalem. In 1918, Turkish resistance collapsed in Asia and Europe. An armistice was concluded in October, and the Ottoman Empire came to an end. The Treaty of Sèvres (see Sèvres, Treaty of) confirmed its dissolution. With the victory of the Turkish nationalists, who had refused to accept the peace terms and overthrew the sultan in 1922, modern Turkey's history began.

The Khmer civilization was largely formed by Indian cultural influences. Buddhism flourished side by side with the worship of Shiva and of other Hindu gods, while both religions coalesced with the cult of the deified king. In the Angkor period many Indian scholars, artists, and religious teachers were attracted to the Khmer court, and Sanskrit literature flourished with royal patronage.

The great achievement of the Khmers was in architecture and sculpture. The earliest known Khmer monuments, isolated towers of brick, probably date from the 7th cent. Small temples set on stepped pyramids next appeared. The development of covered galleries led gradually to a great elaboration of plan. Brick was largely abandoned in favor of stone. Khmer architecture reached its height with the construction of Angkor Wat by Suryavarman II (r. 1113-50) and Angkor Thom by Jayavarman VII (r. 1181-c.1218). Sculpture, which also prospered at Angkor, showed a steady development from relative naturalism to a more conventionalized technique. Bas-reliefs, lacking in the earliest monuments, came to overshadow in importance statues in the round; in the later stages of Khmer art hardly a wall was left bare of bas-reliefs, which conveyed in the richness of their detail and vitality a vivid picture of Khmer life.

The Khmers fought repeated wars against the Annamese (see Annam) and the Chams; in the early 12th cent. they invaded Champa, but, in 1177, Angkor was sacked by the Chams. After the founding of Ayuthia (c.1350), Cambodia was subjected to repeated invasions from Thailand, and the Khmer power declined. In 1434, after the Thai captured Angkor, the capital was transferred to Phnom Penh; this event marks the end of the brilliance of the Khmer civilization.

Origins

The Holy Roman Empire was a successor state to the empire founded in 800 by Charlemagne (see also Carolingians), who revived the title of Roman emperor in the West. According to Carolingian theory, the Roman Empire had merely been suspended, not ended, by the abdication of the last Roman emperor in 476. In 800, Pope Leo III crowned Charlemagne Roman emperor, probably perceived more as a personal title than as a reference to a particular territorial rule. From the death of Arnulf (899), the last Carolingian to hold the imperial title, until Otto's coronation in Rome by Pope John XII, various rulers bore the imperial title but exercised no authority; among them were Louis III, king of Provence, and Berengar I, king of Italy.

Nature of the Empire

From the time of Otto's reign the imperial office was based on the German kingship. The German king, elected by the German princes, automatically sought imperial coronation by the pope. After 1045 a king who was not yet crowned emperor was known as king of the Romans, a title that asserted his right to the imperial throne and implied that he was emperor-designate. Not every German king became emperor, however, because the popes, especially when elections to the kingships were disputed, often claimed that the selection of the emperor was their prerogative. Despite the fact that the German kingship and the imperial office were technically elective, they tended to become hereditary.

At times the electors, the German princes who approved the succession to the German kingship, exercised real authority in choosing the king, although papal confirmation was still necessary for accession to the imperial throne. In 1338 at the diets of Rhense and Frankfurt the German princes proclaimed the electors' right to choose the emperor without papal intervention. The Golden Bull of 1356 issued by Charles IV reaffirmed this and regulated the election procedure. Emperors continued to be crowned by the pope until after the coronation (1530) of Charles V. Thereafter, following the precedent (1508) of Maximilian I, they were crowned at Frankfurt. Several early emperors were also crowned king of Italy with the iron crown of the Lombards. After 1438 the imperial office was held, with one exception, by the house of Hapsburg.

The empire was justified by the claim that, just as the pope was the vicar of God on earth in spiritual matters, so the emperor was God's temporal vicar; hence he claimed to be the supreme temporal ruler of Christendom. Actually, the power of the emperor never equaled his pretensions. Although the emperors were accorded diplomatic precedence over other rulers, their suzerainty early ceased over France, S Italy, Denmark, Poland, and Hungary; and their control over England, Sweden, and Spain was never more than nominal. The authority of the emperors in Italy and Germany was sometimes nonexistent, sometimes real.

The territorial limits of the empire varied, but it generally included Germany, Austria, Bohemia and Moravia, parts of N Italy, present-day Belgium, and, until 1648, the Netherlands and Switzerland. Some countries (e.g., Hungary) were ruled by the emperor or imperial prince but were outside the empire, while others (e.g., Flanders, Pomerania, Schleswig, and Holstein) were part of the empire but were ruled by foreign princes who held their lands in fief from the emperor and took part in the imperial diet.

History

When Otto I became emperor, he renewed the traditions of the Carolingian empire that had been eroding for decades before Arnulf's death. Otto's empire comprised the German duchies, Lorraine (or Lotharingia), Italy, and Burgundy, which had its own nominal king. Burgundy (see Arles, kingdom of) was formally annexed in 1033.

The imperial position, however, was precarious from the start. A conflict over the relationship between the papacy and the imperial throne resulted in the investiture controversy during the reign of Henry IV (1084-1105), who appointed bishops to three sees already under the direction of papal appointees. He was also suspected of tolerating simony and other practices that the pope was trying to curb. In 1076, Henry IV withdrew his obedience to Pope Gregory VII and was excommunicated. Subsequent struggles between the popes Alexander III, Gregory IX, and Innocent IV and the emperors Frederick I and Frederick II concerned papal sovereignty in Italy. The papacy was victorious, and the emperors ceased to interfere seriously with papal affairs except during the Great Schism (see Schism, Great) of the 15th cent. and in the Italian Wars of the 16th cent.

Also untenable was the dual position of the emperors as rulers of Germany and of Italy; geography as well as cultural and political conditions separated the two countries. The defense of the empire against foreign attack was made more difficult by the repeated attempts of the emperors to maintain their authority in Italy against the opposition of the city-states (see commune), the papacy, and the petty princes. Frederick I failed to suppress the Lombard League, which had papal support. Frederick II, after inheriting Naples and Sicily, was primarily interested in Italian affairs; his conflict with the papacy produced the feud between Guelphs and Ghibellines throughout Italy and ruined the imperial authority there.

The death (1254) of Conrad IV, the last ruling Hohenstaufen, was followed by an interregnum of 19 years. Opposing claimants to the imperial crown were unable to exercise authority during this period, and the power of the emperor declined considerably. The election (1273) of Rudolf I as the first Hapsburg German king restored some order, but after his death rival claimants renewed the strife. The effect of continued warfare and weak monarchs increased the power of the German princes, particularly the dukes of the great duchies of Bavaria, Saxony, Swabia, Franconia, Thuringia, and Upper and Lower Lorraine. The Golden Bull of 1356 conceded the princes' dominance over the monarchy.

The emperors maintained some authority against the nobles with the support of the towns and of the great ecclesiastical princes (e.g., the archbishop-electors of Cologne, Mainz, and Trier), who were imperial appointees. As the German towns grew in wealth and power, they entered leagues for defense against the nobles. Since they acted as a counterbalance to the nobility, they were generally favored by the emperors, who made them free imperial cities with a voice in the diet. The power of the emperors, however, had come to depend largely on the size and wealth of the emperors' hereditary domains. Thus, the Luxemburg emperors (Henry VII, Charles IV, Wenceslaus, and Sigismund) and the Hapsburg emperors concerned themselves with their own lands to the detriment of the unity of the empire.

During the reign of Maximilian I (1493-1519) the conflict between the dynastic policy of the Hapsburg emperors and the interests of the German empire (then known as the Holy Roman Empire of the German Nation) became pronounced. The princes attempted to remove the administration of the empire from the emperor and put it in the hands of an imperial council; the council would control all external and internal affairs of the empire. Under pressure Maximilian I created (1500) a council (see Reichsregiment) and an imperial court of justice. However, these were only temporary measures, since the Hapsburgs had no intention of pursuing German policy, which would conflict with their dynastic interests, particularly in Austria.

In the 16th cent., under Charles V and Ferdinand I, imperial and Austrian affairs were practically identical. This identity was furthered by the Reformation, which generally aligned the German Protestant princes against the emperors, who championed Roman Catholicism. In the Thirty Years War (1618-48; see Ferdinand II; Ferdinand III; Wallenstein; Protestant Union) the emperor, allied with Spain, opposed the Protestant princes, who were allied chiefly with Sweden and France. The struggle ended with the virtual dissolution of the empire in the Peace of Westphalia (1648; see Westphalia, Peace of), which recognized the sovereignty of all the states of the empire; the only limitation was that the princes could not make alliances directed against the empire or the emperor.

Although the imperial title became largely honorific, the outward forms of the empire were retained; the emperors, with their hereditary lands, remained powerful monarchs. While the peace generally legalized the situation that had existed in the empire since the Reformation, it also advanced the growth of particularism and absolutism in the German states. The emperors suffered further loss of prestige in their wars against Louis XIV (see Dutch Wars 3; Grand Alliance, War of the; Spanish Succession, War of the).

The death (1740) of Charles VI ended the male Hapsburg line, precipitating further conflict (see Austrian Succession, War of the; Seven Years War). While the elector of Bavaria was chosen (1742) emperor as Charles VII, Maria Theresa, daughter of Charles VI, defended her Hapsburg inheritance against the claims of Bavaria, Prussia, and Saxony. By the peace of Hubertusburg (1763), Francis I, husband of Maria Theresa, was recognized as emperor; however, Prussia, under King Frederick II, had emerged as the leading German power. Joseph II, successor of Francis I, adhered to the principles of the Enlightenment; he attempted to rationalize the administration of the imperial government but failed in the face of resistance by the particularist princes, especially Frederick II of Prussia.

During the French Revolutionary Wars the empire was completely reorganized by the treaty of Lunéville (1801) and by action of the diet in 1803. The number of states was greatly reduced, and the remaining states were aggrandized at the expense of the petty princedoms and ecclesiastical estates. In 1804, Holy Roman Emperor Francis II took the title Francis I, emperor of Austria, and after the establishment (1806) of the Confederation of the Rhine under Napoleon I, Francis renounced his title as Holy Roman Emperor. After the fall of Napoleon no attempt was made to restore the empire, but a German Confederation was established that lasted until 1866.

Throughout its existence the Byzantine Empire was subject to important changes in its boundaries. The core of the empire consisted of the Balkan Peninsula (i.e., Thrace, Macedonia, Epirus, Greece proper, the Greek isles, and Illyria) and of Asia Minor (present-day Turkey). The empire combined Roman political tradition, Hellenic culture, and Christian beliefs. Greek was the prevalent language, but Latin long continued in official use.

See the table entitled Rulers of the Byzantine Empire for a list of all the Byzantine emperors and the years they reigned.

Early Centuries

The characteristic Eastern influence began with Constantine I, who also introduced Christianity. Orthodoxy triumphed over Arianism under Arcadius' predecessor, Theodosius I, but violent religious controversy was chronic. The reigns (395-527) of Arcadius, Theodosius II, Marcian, Leo I, Leo II, Zeno, Anastasius I, and Justin I were marked by the invasions of the Visigoths under Alaric I, of the Huns of Attila, and of the Avars, the Slavs, the Bulgars (see Bulgaria), and the Persians. After the Western Empire fell (476) to Odoacer, Italy, Gaul, and Spain were theoretically united under Zeno but were actually dominated by, respectively, the Ostrogoths, the Franks, and the Visigoths, while Africa was under the Vandals. During this period arose the heresies of Nestorianism and Monophysitism and the political parties of Blues and Greens to divide the Byzantines.

Revival and Hellenization

Under the rule (527-65) of Justinian I and Theodora, Byzantine power grew. Their great generals, Belisarius and Narses, checked the Persians, repressed political factions, and recovered Italy and Africa, while Tribonian helped the emperor to codify Roman law. During Justinian's reign a great revival of Hellenism took place in literature, and Byzantine art and architecture entered their most glorious period.

Much was lost again under his successors. The Lombards conquered most of Italy; however, the Pentapolis (Rimini, Ancona, Fano, Pesaro, and Senigallia), Rome, Sardinia, Corsica, Liguria, and the coasts of S Italy and Sicily long remained under Byzantine rule, and at Ravenna the exarchs governed until 751. The Persians, under Khosrow I, made great gains against the empire, though Emperor Maurice temporarily checked them in 591.

The emperor Heraclius (610-41) defeated the Persians but was barely able to save Constantinople from the Avars. Muslim conquests soon afterward wrested Syria, Palestine, Egypt, Africa, and Sicily from the empire. Heraclius's attempt to reconcile Monophysitism and orthodoxy merely led to the new heresy of Monotheletism. His military reorganization of the provinces into themes proved effective and was continued by Constans II (641-48). Constantine IV (668-85) saved Constantinople from Arab attack.

The 7th cent. was marked by increasing Hellenization of the empire, outwardly symbolized by the adoption of the Greek title Basileus by the emperors. The church, under the patriarch of Constantinople, became increasingly important in public affairs. Theology, cultivated by emperors and monks alike, was pushed to extremes of subtlety. Literature and art became chiefly religious.

Under Justinian II and his successors the empire was again menaced by Arabs and Bulgars, but the Isaurian emperors Leo III (717-41) and Constantine V stopped the Arab advance and recovered Asia Minor. The grave issue of iconoclasm, which they precipitated, led to the loss of Rome. In 800, during the reign of Irene, the Frank Charlemagne was crowned emperor of the West at Rome. Thus ended even the theoretical primacy of Byzantium over Europe.

A Truly Eastern State

The political division of East and West was paralleled by a religious schism, intensified by the patriarch Photius, between the Roman and the Orthodox Eastern Church, later culminating in a complete break (1054). In all aspects the Byzantine Empire, having lost its claim to universality, became a Greek monarchy, though Constantinople still remained the center of both Greek and Roman civilization. Compared with its intellectuals, artists, writers, and artisans, those of Western Europe were crude and barbarous, though sometimes more vigorous and original.

In the empire the administrative machinery was huge, and competition among the courtiers was intense. Complex diplomacy, intrigue, and gross violence marked the course of events; yet moral decay did not prevent such emperors as Basil I, founder of the Macedonian dynasty, and his successors (notably Leo VI, Romanus I, Constantine VII, Nicephorus II, John I, and Basil II) from giving the empire a period of splendor and power (867-1025). The eastern frontier was pushed to the Euphrates River, the Bulgars were subjugated, and the Balkan Peninsula was recovered. Russia, converted to Christianity, became an outpost of Byzantine culture. In the unceasing struggle between the great landowners and the small peasantry, most of the emperors favored the peasants. Economic prosperity was paralleled by a new golden age in science, philosophy, and architecture.

The Ebb of Power

With the rule of Zoë (1028-50) anarchy and decline set in. The Seljuk Turks increased their attacks, and with the defeat (1071) of Romanus IV at Manzikert most of Asia Minor was permanently lost. The Normans under Robert Guiscard and Bohemond I seized S Italy and attacked the Balkans. Venice ruled the Adriatic and challenged Byzantine commercial dominance in the East, and the Bulgars and Serbs reasserted their independence.

Alexius I (1081-1118) took advantage of the First Crusade (see Crusades) to recover some territory in Asia Minor and to restore Byzantine prestige, but his successors of the Comnenus dynasty were at best able to postpone the disintegration of the empire. After the death (1180) of Manuel I the Angelus dynasty unwittingly precipitated the cataclysm of the Fourth Crusade. In 1204 the Crusaders and the Venetians sacked Constantinople and set up a new empire (see Constantinople, Latin Empire of) in Thrace, Macedonia, and Greece. The remainder of the empire broke into independent states, notably the empires of Nicaea and of Trebizond and the despotate of Epirus.

In 1261 the Nicaean emperor Michael VIII conquered most of the tottering Latin empire and reestablished the Byzantine Empire under the Palaeologus family (1261-1453). The reconstructed empire was soon attacked from all sides, notably by Charles I of Naples, by Venice, by the Ottoman Turks, by the new kingdoms of Serbia and Bulgaria, and by Catalonian adventurers under Roger de Flor. At the same time, the empire began to break down from within—the capital was at odds with the provinces; ambitious magnates were greedy for land and privileges; religious orders fought each other vigorously; and church and state were rivals for power.

Eventually the Turks encircled the empire and reduced it to Constantinople and its environs. Manuel II and John VIII vainly asked the West for aid, and, in 1453, Constantinople fell to Sultan Muhammad II after a final desperate defense under Constantine XI. This is one of the dates conventionally accepted as the beginning of the modern age. The collapse of the empire opened the way for the vast expansion of the Ottoman Empire to Vienna itself and also enabled Ivan III of Russia, son-in-law of Constantine XI, to claim a theoretical succession to the imperial title.

The First Empire

The origins of the empire date from the late 16th cent. with the private commercial ventures, chartered and encouraged by the crown, of chartered companies. These companies sometimes had certain powers of political control as well as commercial monopolies over designated geographical areas. Usually they began by setting up fortified trading posts, but where no strong indigenous government existed the English gradually extended their powers over the surrounding area. In this way scattered posts were established in India and the East Indies (for spices, coffee, and tea), defying Portuguese and later Dutch hegemony, and in Newfoundland (for fish) and Hudson Bay (for furs), where the main adversaries were the French.

In the 17th cent. European demand for sugar and tobacco led to the growth of plantations on the islands of the Caribbean and in SE North America. These colonies, together with those established by Roman Catholics and Protestant dissenters in NE North America, attracted a considerable and diversified influx of European settlers. Organized by chartered companies, the colonies soon developed representative institutions, evolving from the company governing body and modeled on English lines.

The need for cheap labor to work the plantations fostered the growth of the African slave trade. New chartered companies secured posts on the African coasts as markets for captured slaves from the interior. An integrated imperial trade arose, involving the exchange of African slaves for West Indian molasses and sugar, English cloth and manufactured goods, and American fish and timber. To achieve the imperial self-sufficiency required by prevailing theories of mercantilism, and, more immediately, to increase British wealth and naval strength, the Navigation Acts were passed, restricting colonial trade exclusively to British ships and making England the sole market for important colonial products.

Developments in the late 17th and early 18th cent. were characterized by a weakening of the Spanish and Dutch empires, exposing their territories to British encroachment, and by growing Anglo-French rivalry in India, Canada, and Africa. At this time the British government attempted to assert greater direct control over the expanding empire. In the 1680s the revision of certain colonial charters to bring the North American and West Indian colonies under the supervision of royal governors resulted in chronic friction between the governors and elected colonial assemblies.

The early 18th cent. saw a reorganization and revitalization of many of the old chartered companies. In India, from the 1740s to 1763, the British East India Company and its French counterpart were engaged in a military and commercial rivalry in which the British were ultimately victorious. The political fragmentation of the Mughal empire permitted the absorption of one area after another by the British. The Treaty of Paris (1763; see under Paris, Treaty of) firmly established the British in India and Canada, but the financial burdens of war involved the government in difficulties with the American colonies. The success of the American Revolution marked the end of the first British Empire.

The Second Empire

The voyages of Capt. James Cook to Australia and New Zealand in the 1770s and new conquests in India after 1763 opened a second phase of territorial expansion. The victories of the Napoleonic Wars added further possessions to the empire, among them Cape Colony, Mauritius, Ceylon (Sri Lanka), Trinidad and Tobago, St. Lucia, British Guiana (Guyana), and Malta. During the second empire mercantilist ideals and regulations were gradually abandoned in response to economic and political developments in Great Britain early in the 19th cent. Britain's new industrial supremacy lent greater force to doctrines of free trade, which, as part of their critique of mercantilism, questioned the economic value of political ties between the colonies and the mother country.

The plight of large nonwhite populations within the empire became a matter of concern to humanitarians. Abolition of the slave trade (1807) and of slavery (1833) was accompanied in the colonies by efforts to improve the lot of indigenous groups. Better communications and the establishment of a regular civil service facilitated the development of a more efficient colonial administration. But the growth, notably in the English-speaking colonies, of national identity and of relative national self-sufficiency, as well as a trend of opinion in Britain favoring colonial self-government, made the British, now engaged in liberalizing their own governing institutions, willing to concede certain powers of self-government to the white colonies. In 1839, Lord Durham, in response to unrest in Canada, issued his "Report on the Affairs of British North America." Durham stated that to retain its colonies Britain should grant them a large measure of internal self-government.

The British North America Act of 1867 inaugurated a pattern of devolution followed in most of the European-settled colonies by which Parliament gradually surrendered its direct governing powers; thus Australia and New Zealand followed Canada in becoming self-governing dominions. On the other hand, the British assumed greater responsibility in Africa and in India, where the Indian Mutiny had resulted (1858) in the final transfer of power from the East India Company to the British government. To govern territories with large indigenous populations, the crown colony system was developed. Such colonies, of which one of the most enduring was Hong Kong, were ruled by a British governor and consultative councils composed primarily of the governor's nominees; these, in turn, often delegated considerable powers of local government to local rulers.

In the later decades of the 19th cent. there occurred a revival of European competition for empire in which the British acquired or consolidated vast holdings in Africa—such as Nigeria, the Gold Coast (later Ghana), Rhodesia (Zambia and Zimbabwe), South Africa, and Egypt—and in Asia—such as Burma (Myanmar) and Malaya. The size and wealth of the empire and the anxieties produced by European colonial competition stimulated a desire for imperial solidarity. The Imperial Conference, begun in 1887, represented an attempt to strengthen Britain's ties with those colonies that had become self-governing territories.

From Empire to Commonwealth

World War I brought the British Empire to the peak of its expansion, but in the years that followed came its decline. Victory added, under the system of mandates, new territories, including Palestine, Transjordan, Iraq, and several former German territories in Africa and Asia. Imperial contributions had considerably strengthened the British war effort (more than 200,000 men from the overseas empire died in the war; the dominions and India signed the Versailles Treaty and joined the League of Nations), but at the same time expectations were raised among colonial populations that an increased measure of self-government would be granted.

Nationalist agitation against economic disparities, often stimulated by acts of racial discrimination by British settlers, was particularly strong in India (see Indian National Congress) and in parts of Africa. Although loath to lessen its hold over countries it had done much to develop, and thereby to incur great economic and political loss, Britain gradually capitulated to the pressures of nationalist sentiment. Iraq gained full sovereignty in 1932; British privileges in Egypt were modified by treaty in 1936; and concessions were made toward self-government in India and later in the African colonies.

In 1931 the Statute of Westminster officially recognized the independent and equal status under the crown of the former dominions within a British Commonwealth of Nations, thus marking the advent of free cooperation among equal partners. After World War II self-government advanced rapidly in all parts of the empire. In 1947, India was partitioned and independence granted to the new states of India and Pakistan. In 1948 the mandate over Palestine was relinquished, and Burma (Myanmar) gained independence as a republic. Other parts of the empire, notably in Africa, gained independence and subsequently joined the Commonwealth.

Great Britain still administers many dependencies throughout the world. They include Gibraltar in the Mediterranean; the Falkland Islands, South Georgia, the South Sandwich Islands, and St. Helena (including Ascension and Tristan da Cunha) in the South Atlantic; Anguilla, Bermuda, the British Virgin Islands, the Cayman Islands, Montserrat, and the Turks and Caicos Islands in the West Indies; and Pitcairn Island in the Pacific. These dependencies have varying degrees of self-government. In 1982 Britain clashed with Argentina over the Falkland Islands, retaking them by force after Argentina had invaded them to back up its claims of sovereignty.

State policy, practice, or advocacy of extending power and dominion, especially by direct territorial acquisition or by gaining political and economic control of other areas. Because imperialism always involves the use of power, often in the form of military force, it is widely considered morally objectionable, and the term accordingly has been used by states to denounce and discredit the foreign policies of their opponents. Imperialism in ancient times is clear in the unending succession of empires in China, western Asia, and the Mediterranean. Between the 15th century and the middle of the 18th, England, France, the Netherlands, Portugal, and Spain built empires in the Americas, India, and the East Indies. Russia, Italy, Germany, the United States, and Japan became imperial powers in the period from the middle of the 19th century to World War I. The imperial designs of Japan, fascist Italy, and Nazi Germany in the 1930s culminated in the outbreak of World War II. After the war the Soviet Union consolidated its military and political control of the states of eastern Europe (see Iron Curtain). From the early 20th century the U.S. was accused of imperialism for intervening in the affairs of developing countries in order to protect the interests of U.S.-owned international corporations (see United Fruit Co.). Economists and political theorists have debated whether imperialism benefits the states that practice it and whether such benefits or other reasons ever justify a state in pursuing imperialist polices. Some theorists, such as Niccolò Machiavelli, have argued that imperialism is the justified result of the natural struggle for survival among peoples. Others have asserted that it is necessary in order to ensure national security. A third justification for imperialism, offered only infrequently after World War II, is that it is a means of liberating peoples from tyrannical rule or bringing them the blessings of a superior way of life.

Former empire centred in Anatolia. It was named for Osman I (1259–1326), a Turkish Muslim prince in Bithynia who conquered neighbouring regions once held by the Seljūq dynasty and founded his own ruling line circa 1300. Ottoman troops first invaded Europe in 1345, sweeping through the Balkans. Though defeated by Timur in 1402, by 1453 the Ottomans, under Mehmed II (the Conquerer), had destroyed the Byzantine Empire and captured its capital, Constantinople (now Istanbul), which henceforth served as the Ottoman capital. Under Selim I (r. 1512–20) and his son Süleyman I (the Magnificent; 1520–66), the Ottoman Empire reached its greatest peak. Süleyman took control of parts of Persia, most of Arabia, and large sections of Hungary and the Balkans. By the early 16th century the Ottomans had also defeated the Mamlūk dynasty in Syria and Egypt; and their navy under Barbarossa soon seized control of much of the Barbary Coast. Beginning with Selim, the Ottoman sultans also held the h1 of caliph, the spiritual head of Islam. Ottoman power began to decline in the late 16th century. Ottoman forces repeatedly besieged Vienna. After their final effort at taking the Austrian capital failed (1683), that and subsequent losses led them to relinquish Hungary in 1699. Corruption and decadence gradually undermined the government. In the late 17th and 18th centuries the Russo-Turkish Wars and wars with Austria and Poland further weakened the empire, which in the 19th century came to be called the “sick man of Europe.” Most of its remaining European territory was lost in the Balkan Wars (1912–13). It sided with Germany in World War I (1914–18); postwar treaties dissolved the empire, and in 1922 the sultanate was abolished by Mustafa Kemal Atatürk, who proclaimed the Republic of Turkey the following year. Seealso Janissary; Turk; Young Turks.

Independent principality (1204–61) of the fragmented Byzantine Empire. Founded in 1204 by Theodore I Lascaris, it was the political and cultural centre from which a restored Byzantium arose in the mid-13th century under Michael VIII Palaeologus. It extended from the Black Sea coast east of the Sangarius River southwest across western Anatolia to Miletus and the Menderes (Maeander) River. It became a centre of Greek education, especially under Theodore II Lascaris, who founded an imperial school. It declined after 1261, when Michael VIII regained the Byzantine capital of Constantinople.

Trading empire that flourished in West Africa in the 13th–16th centuries. It developed from the state of Kangaba on the upper Niger River and was probably founded before AD 1000. The Malinke inhabitants of Kangaba acted as middlemen in the gold trade in ancient Ghana. Growing in the 13th century under the leadership of Sundiata, it continued to expand in the 14th century and absorbed Gao and Timbuktu. Its boundaries extended to the Hausa people in the east and to Fulani and Tukulor peoples in the west. It eventually outgrew its political and military strength, and many of its subject areas revolted. By circa 1550 it had ceased to be an important political entity.

Realm of varying extent in medieval and modern western and central Europe. Traditionally believed to have been established by Charlemagne, who was crowned emperor by Pope Leo III in 800, the empire lasted until the renunciation of the imperial h1 by Francis II in 1806. The reign of the German Otto I (the Great; r. 962–973), who revived the imperial h1 after Carolingian decline, is also sometimes regarded as the beginning of the empire. The name Holy Roman Empire (not adopted until the reign of Frederick I Barbarossa) reflected Charlemagne's claim that his empire was the successor to the Roman Empire and that this temporal power was augmented by his status as God's principal vicar in the temporal realm (parallel to the pope's in the spiritual realm). The empire's core consisted of Germany, Austria, Bohemia, and Moravia. Switzerland, the Netherlands, and northern Italy sometimes formed part of it; France, Poland, Hungary, and Denmark were initially included, and Britain and Spain were nominal components. From the mid-11th century the emperors engaged in a great struggle with the papacy for dominance, and, particularly under the powerful Hohenstaufen dynasty (1138–1208, 1212–54), they fought with the popes over control of Italy. Rudolf I became the first Habsburg emperor in 1273, and from 1438 the Habsburg dynasty held the throne for centuries. Until 1356 the emperor was chosen by the German princes; thereafter he was formally elected by the electors. Outside their personal hereditary domains, emperors shared power with the imperial diet. During the Reformation the German princes largely defected to the Protestant camp, opposing the Catholic emperor. At the end of the Thirty Years' War, the Peace of Westphalia (1648) recognized the individual sovereignty of the empire's states; the empire thereafter became a loose federation of states and the h1 of emperor principally honorific. In the 18th century, issues of imperial succession resulted in the War of the Austrian Succession and the Seven Years' War. The greatly weakened empire was brought to an end by the victories of Napoleon. Seealso Guelphs and Ghibellines; Investiture Controversy; Concordat of Worms.

First of the great medieval trading empires of western Africa (7th–13th century). Located in what is now southeastern Mauritania and part of Mali, it acted as intermediary between Arab and Berber salt traders to the north and gold and ivory producers to the south. Gold was secured through barter from those living at the empire's southern limit and exchanged in the capital for commodities, especially salt. As the empire grew richer it extended its reach, incorporating gold-producing southern lands and cities to the north. The king exacted tribute from the princes of subject tribes. Ghana began to decline with the rise of the Muslim Almoravids; the Almoravid leader Abu Bakr seized the Ghanaian capital of Kumbi in 1076. The empire's subject peoples began to break away, and in 1240 the empire's remains were incorporated into the Sundiata empire of Mali.

Style of furniture and interior decoration that flourished in France during the First Empire (1804–14). It corresponds to the Regency style in England. Responding to the desire of Napoleon for a style inspired by imperial Rome, the architects Charles Percier (1764–1838) and Pierre Fontaine (1762–1853) decorated his state rooms with Classical styles of furniture and ornamental motifs, supplemented by sphinxes and palm leaves to commemorate his Egyptian campaigns. The style influenced the arts (Jacques-Louis David in painting, Antonio Canova in sculpture, the Arc de Triomphe in architecture) and fashion and spread quickly throughout Europe.

Empire, southeastern and southern Europe and western Asia. It began as the city of Byzantium, which had grown from an ancient Greek colony founded on the European side of the Bosporus. The city was taken in AD 330 by Constantine I, who refounded it as Constantinople. The area at this time was generally termed the Eastern Roman Empire. The fall of Rome in 476 ended the western half of the Roman Empire; the eastern half continued as the Byzantine Empire, with Constantinople as its capital. The eastern realm differed from the west in many respects: heir to the civilization of the Hellenistic era, it was more commercial and more urban. Its greatest emperor, Justinian (r. 527–565), reconquered some of western Europe, built the Hagia Sophia, and issued the basic codification of Roman law. After his death the empire weakened. Though its rulers continued to style themselves “Roman” long after Justinian's death, “Byzantine” more accurately describes the medieval empire. The long controversy over iconoclasm within the eastern church prepared it for the break with the Roman church (see Schism of 1054). During the controversy, Arabs and Seljuq Turks increased their power in the area. In the late 11th century, Alexius I Comnenus sought help from Venice and the pope; these allies turned the ensuing Crusades into plundering expeditions. In the Fourth Crusade the Venetians took over Constantinople and established a line of Latin emperors. Recaptured by Byzantine exiles in 1261, the empire was now little more than a large city-state. In the 14th century the Ottoman Turks began to encroach; their extended siege of Constantinople ended in 1453, when the last emperor died fighting on the city walls and the area came under Ottoman control.

Worldwide system of dependencies—colonies, protectorates, and other territories—that over a span of three centuries came under the British government. Territorial acquisition began in the early 17th century with a group of settlements in North America and West Indian, South Asian, and African trading posts founded by private individuals and trading companies. In the 18th century the British took Gibraltar, established colonies along the Atlantic seacoast of North America and in the Caribbean Sea, and began to add territory in India. With its victory in the French and Indian War (1763), the empire secured Canada and the eastern Mississippi Valley and gained supremacy in India. From the late 18th century it began to build power in Malaya and acquired the Cape of Good Hope, Ceylon (see Sri Lanka), and Malta. The British settled Australia in 1788 and subsequently New Zealand. Aden was secured in 1839, and Hong Kong in 1841. Britain went on to control the Suez Canal (1875–1956). In the 19th-century European partition of Africa, Britain acquired Nigeria, Egypt, the territories that would become British East Africa, and part of what would become the Union (later Republic) of South Africa. After World War I, Britain secured mandates to German East Africa, part of the Cameroons, part of Togo, German South-West Africa, Mesopotamia, Palestine, and part of the German Pacific islands. Britain gradually evolved a system of self-government for some colonies after the U.S. gained independence, as set forth in Lord Durham's report of 1839. Dominion status was given to Canada (1867), Australia (1901), New Zealand (1907), the Union of South Africa (1910), and the Irish Free State (1921). Britain declared war on Germany in 1914 on behalf of the entire empire; after World War I the dominions signed the peace treaties themselves and joined the League of Nations as independent states. In 1931 the Statute of Westminster recognized them as independent countries “within the British Empire,” referring to the “British Commonwealth of Nations,” and from 1949, the Commonwealth of Nations. The British Empire, therefore, developed into the Commonwealth in the mid-20th century, as former British dependencies obtained sovereignty but retained ties to the United Kingdom.
