In the wake of the 1947–48 Civil War in Mandatory Palestine, a riot against the Jewish community of Manama, in the British Protectorate of Bahrain, on December 5, 1947. A mob of Iranian and Trucial States sailors ran through the Manama Souq looted Jewish homes and shops, and destroyed the synagogue. One Jewish woman died; she was either killed or died from fright.
After the riots, Bahraini Jews left en masse, some emigrating to Israel, others to England or America. They were allowed to leave with their property, although they were forced to give up their citizenship. An estimated 500 to 600 Jews remained in Bahrain until riots broke out after the Six Day War in 1967; as of 2006 only 36 remained.
