As stated in the Boston College Guide to Passion Plays, "Over the course of time, Christians began to accept... that the Jewish people as a whole were responsible for killing Jesus. According to this interpretation, both the Jews present at Jesus’ death and the Jewish people collectively and for all time, have committed the sin of deicide, or God-killing. For 1900 years of Christian-Jewish history, the charge of deicide has led to hatred, violence against and murder of Jews in Europe and America."
This accusation was repudiated in 1964, when the Catholic Church under Pope Paul VI issued the document Nostra Aetate as a part of Vatican II.
Although the Pope Clement VI tried to protect them by the July 6, 1348 papal bull and another 1348 bull, several months later, 900 Jews were burnt in Strasbourg, where the plague hadn't yet affected the city. Clement VI condemned the violence and said those who blamed the plague on the Jews (among whom were the flagellants) had been "seduced by that liar, the Devil."
On many occasions, Jews were accused of a blood libel, the supposed drinking of blood of Christian children in mockery of the Christian Eucharist. (Early Christians had been accused of a similar practice based on pagan misunderstanding of the Eucharist ritual.) According to the authors of these blood libels, the 'procedure' for the alleged sacrifice was something like this: a child who had not yet reached puberty was kidnapped and taken to a hidden place. The child would be tortured by Jews, and a crowd would gather at the place of execution (in some accounts the synagogue itself) and engage in a mock tribunal to try the child. The child would be presented to the tribunal naked and tied and eventually be condemned to death. In the end, the child would be crowned with thorns and tied or nailed to a wooden cross. The cross would be raised, and the blood dripping from the child's wounds would be caught in bowls or glasses and then drunk. Finally, the child would be killed with a thrust through the heart from a spear, sword, or dagger. Its dead body would be removed from the cross and concealed or disposed of, but in some instances rituals of black magic would be performed on it. This method, with some variations, can be found in all the alleged Christian descriptions of ritual murder by Jews.
The story of William of Norwich (d. 1144) is often cited as the first known accusation of ritual murder against Jews. The Jews of Norwich, England were accused of murder after a Christian boy, William, was found dead. It was claimed that the Jews had tortured and crucified their victim. The legend of William of Norwich became a cult, and the child acquired the status of a holy martyr. Recent analysis has cast doubt on whether this was the first of the series of blood libel accusations but not on the contrived and antisemitic nature of the tale.
During the Middle Ages blood libels were directed against Jews in many parts of Europe. The believers of these accusations reasoned that the Jews, having crucified Jesus, continued to thirst for pure and innocent blood and satisfied their thirst at the expense of innocent Christian children. Following this logic, such charges were typically made in Spring around the time of Passover, which approximately coincides with the time of Jesus' death.
The story of Little Saint Hugh of Lincoln (d. 1255) said that after the boy was dead, his body was removed from the cross and laid on a table. His belly was cut open and his entrails were removed for some occult purpose, such as a divination ritual. The story of Simon of Trent (d. 1475) emphasized how the boy was held over a large bowl so all his blood could be collected.
More recently blood libel stories have appeared a number of times in the state-sponsored media of a number of Arab nations, in Arab television shows, and on websites.
Jews were subject to a wide range of legal restrictions throughout the Middle Ages, some of which lasted until the end of the 19th century. Jews were excluded from many trades, the occupations varying with place and time, and determined by the influence of various non-Jewish competing interests. Often Jews were barred from all occupations but money-lending and peddling, with even these at times forbidden. The number of Jews permitted to reside in different places was limited; they were concentrated in ghettos, and were not allowed to own land; they were subject to discriminatory taxes on entering cities or districts other than their own, were forced to swear special Jewish Oaths, and suffered a variety of other measures, including restrictions on dress.
The Fourth Lateran Council in 1215 was the first to proclaim the requirement for Jews to wear something that distinguished them as Jews. It could be a coloured piece of cloth in the shape of a star or circle or square, a hat (Judenhut), or a robe. In many localities, members of the medieval society wore badges to distinguish their social status. Some badges (such as guild members) were prestigious, while others ostracised outcasts such as lepers, reformed heretics and prostitutes. Jews sought to evade the badges by paying what amounted to bribes in the form of temporary "exemptions" to kings, which were revoked and re-paid whenever the king needed to raise funds.
The mobs accompanying the first three Crusades, and particularly the People's Crusade accompanying the first Crusade, attacked the Jewish communities in Germany, France, and England, and put many Jews to death. Entire communities, like those of Treves, Speyer, Worms, Mayence, and Cologne, were slain during the first Crusade by a mob army. About 12,000 Jews are said to have perished in the Rhenish cities alone between May and July, 1096. Before the Crusades the Jews had practically a monopoly of trade in Eastern products, but the closer connection between Europe and the East brought about by the Crusades raised up a class of merchant traders among the Christians, and from this time onward restrictions on the sale of goods by Jews became frequent. The religious zeal fomented by the Crusades at times burned as fiercely against the Jews as against the Muslims, though attempts were made by bishops during the First crusade and the papacy during the Second Crusade to stop Jews from being attacked. Both economically and socially the Crusades were disastrous for European Jews. They prepared the way for the anti-Jewish legislation of Pope Innocent III, and formed the turning point in the medieval history of the Jews.
In the County of Toulouse (now part of southern France) the Jews were received on good terms until the Albigensian Crusade. Toleration and favour shown to the Jews was one of the main complaints of the Roman Church against the Counts of Toulouse. Following the Crusaders' successful wars against Raymond VI and Raymond VII, the counts were required to discriminate against Jews like other Christian rulers. In 1209, stripped to the waist and barefoot, Raymond VI was obliged to swear that he would no longer allow Jews to hold public office. In 1229 his son Raymond VII, underwent a similar ceremony where he was obliged to prohibit the public employment of Jews, this time at Notre Dame in Paris. Explicit provisions on the subject were included in the Treaty of Meaux (1229). By the next generation a new, zealously Catholic, ruler was arresting and imprisoning Jews for no crime, raiding their houses, seizing their cash, and removing their religious books. They were then released only if they paid a new "tax". A historian has argued that organised and official persecution of the Jews became a normal feature of life in southern France only after the Albigensian Crusade because it was only then that the Church became powerful enough to insist that measures of discrimination be applied.
The practice of expelling the Jews accompanied by confiscation of their property, followed by temporary readmissions for ransom, was utilized to enrich the French crown during 12th-14th centuries. The most notable such expulsions were: from Paris by Philip Augustus in 1182, from the entirety of France by Louis IX in 1254, by Charles IV in 1306, by Charles V in 1322, by Charles VI in 1394.
To finance his war to conquer Wales, Edward I of England taxed the Jewish moneylenders. When the Jews could no longer pay, they were accused of disloyalty. Already restricted to a limited number of occupations, the Jews saw Edward abolish their "privilege" to lend money, choke their movements and activities and were forced to wear a yellow patch. The heads of Jewish households were then arrested, over 300 of them taken to the Tower of London and executed, while others killed in their homes. See also:-Massacres at London and York (1189 – 1190). The complete banishment of all Jews from the country in 1290 led to thousands killed and drowned while fleeing and the absence of Jews from England for three and a half centuries, until 1655, when Oliver Cromwell reversed the policy.
In 1492, Ferdinand II of Aragon and Isabella of Castile issued General Edict on the Expulsion of the Jews from Spain (see also Spanish Inquisition) and many Sephardi Jews fled to the Ottoman Empire, some to the Land of Israel.
The Kingdom of Portugal followed suit and in December 1496, it was decreed that any Jew who did not convert to Christianity would be expelled from the country. However, those expelled could only leave the country in ships specified by the King. When those who chose expulsion arrived at the port in Lisbon, they were met by clerics and soldiers who used force, coercion, and promises in order to baptize them and prevent them from leaving the country. This period of time technically ended the presence of Jews in Portugal. Afterwards, all converted Jews and their descendants would be referred to as "New Christians" or Marranos, and they were given a grace period of thirty years in which no inquiries into their faith would be allowed; this was later to extended to end in 1534. A popular riot in 1504 would end in the death of two thousand Jews; the leaders of this riot were executed by Manuel.
In 1744, Frederick II of Prussia limited Breslau to only ten so-called "protected" Jewish families and encouraged similar practice in other Prussian cities. In 1750 he issued Revidiertes General Privilegium und Reglement vor die Judenschaft: the "protected" Jews had an alternative to "either abstain from marriage or leave Berlin" (quoting Simon Dubnow). In the same year, Archduchess of Austria Maria Theresa ordered Jews out of Bohemia but soon reversed her position, on condition that Jews pay for readmission every ten years. This extortion was known as malke-geld (queen's money). In 1752 she introduced the law limiting each Jewish family to one son. In 1782, Joseph II abolished most of persecution practices in his Toleranzpatent, on the condition that Yiddish and Hebrew are eliminated from public records and judicial autonomy is annulled. Moses Mendelssohn wrote that "Such a tolerance... is even more dangerous play in tolerance than open persecution".
Martin Luther, an Augustinian monk and an ecclesiastical reformer whose teachings inspired the Reformation, wrote antagonistically about Jews in his book On the Jews and their Lies, which describes the Jews in extremely harsh terms, excoriates them, and provides detailed recommendations for a pogrom against them and their permanent oppression and/or expulsion. According to Paul Johnson, it "may be termed the first work of modern antisemitism, and a giant step forward on the road to the Holocaust." In his final sermon shortly before his death, however, Luther preached "We want to treat them with Christian love and to pray for them, so that they might become converted and would receive the Lord." Still, Luther's harsh comments about the Jews are seen by many as a continuation of medieval Christian antisemitism. See also Martin Luther and Antisemitism
