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.

Dagobert I
Frankish King Dagobert I gave Jews the alternatives of conversion to Christianity or exile in 629. Those that did not convert or leave his dominions were killed.

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, and Switzerland.

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