The 1934 Constantine riots was an anti-Jewish riot that erupted in the Algerian city of Constantine.
The general consensus is that the initial cause of the conflict was a confrontation between Eliahou Khalifa, a Jewish Zouave, and Muslim worshippers in a mosque next to his home. The Muslims said that Khalifa was drunk, and insulted Islam. A report by the Jewish authorities claimed he was not intoxicated, and that after getting into an argument with them, the Muslims had cursed Khalifa's faith and he cursed them and their faith back.
