The medieval population of Cork was about 2000 people. It suffered a severe blow in 1349 when almost half the townspeople died of bubonic plague when the Black Death arrived in the town. In 1491 Cork played a part in the English Wars of the Roses when Perkin Warbeck a pretender to the English throne, landed in the city and tried to recruit support for a plot to overthrow Henry VII of England. The mayor of Cork and several important citizens went with Warbeck to England but when the rebellion collapsed they were all captured and executed. Cork's nickname of the 'rebel city' originates in these events.
A description of Cork written in 1577 speaks of the city as, "the fourth city of Ireland" that is, "so encumbered with evil neighbours, the Irish outlaws, that they are fayne to watch their gates hourly...they trust not the country adjoining [and only marry within the town] so that the whole city is linked to each other in affinity"
In 1641, Ireland was convulsed by a Catholic rebellion, in which several thousand of the English Protestant settlers were massacred by the Catholic Irish. Cork became a stronghold for the Protestants, who sought refuge there after the outbreak of the rebellion and remained in Protestant hands throughout the ensuing Irish Confederate Wars. An ineffective Catholic attempt to take the city in 1642 was beaten off at the battle of Liscarroll. In 1644, Murrough O'Brien, Earl Inchiquinn, the commander of English forces in Cork, expelled the Catholic townsmen from city. Although most of them went no further than the city's suburbs, this was the beginning of Protestant domination of the city that would last for nearly two centuries. The population of Cork by this times was around 5000, most of whom lived outside the city walls.
In 1649-53, Ireland was re-conquered by an English Parliamentarian army under Oliver Cromwell. Inchiquin had briefly led Cork into an alliance with the Catholic Confederates, in 1648, but the garrison changed sides again in 1650, going over to English Parliamentarian side under the influence of Roger Boyle, 1st Earl of Orrery.
In 1690, during yet another ethno-religious conflict, the Williamite war in Ireland, Cork was besieged and taken for the Protestant Williamites by an English army under John Churchill, 1st Duke of Marlborough.
During the early 19th century the population of Cork expanded rapidly. By mid century Cork had a population of about 80,000. The increase was due to migration from the countryside as people fled from poverty and in the 1840s, a terrible famine - see Great Irish Famine. This led to extremes of poverty and overcrowding in Cork city during this century. Another effect of this influx was to reverse the denominational character of the city, which became predominantly Catholic again.
However in the later 19th century the population of Cork declined slightly due to emigration, principally to Britain or North America. In 1825, over 1800 Irish residents departed from Cork to emigrate to Peterborough, Ontario, Canada assisted by Peter Robinson (who organized the scheme on behalf of the British Government). This resulted in the area known as "Scott's Plains" being renamed "Peterborough" as a tribute. Cork and also nearby Cobh became major points of departure for Irish emigrants, who left the country in great numbers after the Great Irish Famine of the 1840s.
During the 19th century important industries in Cork included, brewing, distilling, wool and shipbuilding. In addition, there were some municipal improvements such as gas light street lights in 1825, a local paper, The Cork Examiner was first published in 1841 and, very importantly for the development of modern industry, the railway reached Cork in 1849. Also in 1849, University College Cork opened.
Much 19th century architecture can still be seen in many areas around the city such as the neo-Georgian and Victorian buildings that now house Banks and Department stores. The Victorian influence on the city is noticeable in place names such as Victora Cross (after Queen Victoria), Albert Quay (after Prince Albert), Adelaide Street (after Queen Adelaide) and the Victoria Hospital on the Old Blackrock Rd.
Since the nineteenth century, Cork had been a strongly Irish nationalist city, with widespread support for Irish Home Rule and the Irish Parliamentary Party, but from 1910 stood firmly behind William O'Brien's dissident All-for-Ireland Party.
In 1916, during the Easter Rising as many as 1000 Irish Volunteers mobilised in Cork for an armed rebellion against British rule but they dispersed without fighting. However, during the subsequent Irish War of Independence 1919-1921, Cork was the scene of much violence.
In particular, the city suffered from the action of the Black and Tans - a paramilitary police force raised to help the Royal Irish Constabulary combat the Irish Republican Army. On the 20 March 1920, Thomas Mac Curtain, the Sinn Féin Lord Mayor of Cork was shot dead, in front of his wife at his home, by Policemen. His successor as Mayor, Terence McSwiney was arrested in August 1920 and died on hunger strike in October of that year. On December 11 the city centre was gutted by fires started by the Black and Tans in reprisal for IRA attacks in the city. Over 300 buildings were destroyed and two suspected IRA men were shot dead in their beds by British forces on the night. This atrocity did not stop IRA activity in the city however. Attacks and reprisals continued in the city until the fighting was ended in a truce agreed in July 1921.
However, Cork's troubles were not yet over. The local IRA units, for the most part, did not accept the Anglo-Irish Treaty negotiated to end the war -ultimately repudiating the authority of the newly created Irish Free State. After the withdrawal of British troops in June 1922, they took over the military barracks in Cork and the surrounding area. By July 1922, when the Irish Civil War, broke out, Cork was held by anti-Treaty forces as part of a self-styled Munster Republic -intended to be a stronghold for the preservation of the Irish Republic annulled by the Treaty. Cork was retaken in August 1922 by the pro-Treaty National Army in an attack from the sea. The Free State forces landed at nearby Passage West with 1,500 troops and several artillery pieces. The badly armed anti-Treaty forces dispersed after sporadic fighting, burning the barracks they had been holding. Guerrilla warfare raged in the surrounding countryside until April 1923, when the Anti-Treaty side called a ceasfire and dumped their arms.
Cork's inner city slums were cleared by the municipal authority from the 1920s onwards, and their inhabitants were re-housed in housing estates on the periphery of the city -especially on its north side. Many of these new suburbs have since suffered from social deprivation and high crime rates - a pattern repeatedly found in Irish urban development.
Cork's economy dipped in the late 20th century as the old manufacturing industries in Cork declined. The Ford car factory closed in 1980 as did the Dunlop tyre factory. Shipbuilding in Cork also came to an end in the 1980s. As a result of these closures unemployment was high in Cork in the 1980s.
However in the 1990s new industries came to Cork. For instance, Marina Commercial Park was built on the site of the old Dunlop and Ford plants and Cork Airport Business Park first opened in 1999. Cork, like other cities in Ireland has benefited from the Celtic Tiger economic boom and today other industries in Cork include chemicals, brewing, distilling and food processing. Cork is also a busy and important port. Tourism is also an important industry in the city's economic life. In 2005, Cork was the European Capital of Culture.
