Persecution of Jews in Belgium

Roman emperors
Under Christian emperors, Jews were persecuted in the Roman Empire, which included forbidding Jews from marrying Christians, restricting Jewish ownership of slaves, and punishing those that converted from Christianity to Judaism.

Frankish kings
King of the Franks, Chlothar II in 614 forbade Jews to serve in any military or administrative office. His successor Dagobert I demanded that Jews convert to Christianity or leave his dominions in 629. Those that did not convert or leave his dominions were killed.

Charles I
Count Charles I expelled Jews from Flanders in 1125.

Crusaders
After an accusation of blood libel in Tienen in 1308, Crusaders of the abortive Crusade of 1308 and 1309 appeared and killed Jews. In Leuven, Crusaders gave Jews the choice between conversion to Christianity and death.

Persecution of Jews during the Black Death
Jews were falsely blamed for the Black Death or bubonic plague pandemic in Europe during the mid-1300s. They were persecuted and massacred. Jews were often used by Christians to blame due to their resentment of them considering the antisemitic Christian belief that Jews as a people hold the responsibility for killing Jesus Christ or Jewish deicide. Many Jews were murdered in Austria, Belgium, France, Germany, Poland, Spain, Switzerland, and the Netherlands.

Massacre of 1370
After a host desecration accusation, Jews were massacred in Brussels and Leuven in 1370.
