During this period, the substantial Jewish community (probably exceeding 100,000 people) comprised between a quarter and a third of the city's population. On 1 April 1941, members of the "Golden Square" and Rashid Ali staged a coup in Baghdad. Rashid Ali installed a pro-German and pro-Italian government to replace the pro-British government of Regent Abdul Ilah. On 31 May, after the resulting Anglo-Iraqi War and after Rashid Ali and his government had fled, the Mayor of Baghdad surrendered to British and Commonwealth forces. On June 1–2, during the ensuing power vacuum, Jewish residents were attacked following rumors they had aided the British. In what became known as the Farhud, over 180 Jews were killed, 1,000 injured and hundreds of Jewish properties were ransacked. Between 300 and 400 non-Jewish rioters were killed in the attempt to quell the violence.
