From 1951 to 1952, Operation Ezra and Nehemiah airlifted between 120,000 and 130,000 Iraqi Jews to Israel via Iran and Cyprus. The massive emigration of Iraqi Jews was among the most climactic events of the Jewish exodus from Arab and Muslim countries.
The operation is named after Ezra and Nehemiah, who led the Jewish people from exile in Babylonia to return to Israel in the 5th century BC, as recorded in the books of the Hebrew Bible that bear their names.
Most of the $4 million cost of the operation was financed by the American Jewish Joint Distribution Committee.
A change in Iraqi Jewish identity occurred after the violent Farhud against the Jews of Baghdad, on June 1–2, 1941 following the collapse of the pro-Nazi Golden Square regime of Rashid Ali al-Kaylani, during which at least 180 Jews were killed during two days of riots. In some accounts the Farhud marked the turning point for Iraq's Jews. Other historians, however, see the pivotal moment for the Iraqi Jewish community much later, between 1948–51, since Jewish communities prospered along with the rest of the country throughout most of the 1940s, and many Jews who left Iraq following the Farhud returned to the country shortly thereafter and permanent emigration did not accelerate significantly until 1950–51. Either way, the Farhud is broadly understood to mark the start of a process of politicization of the Iraqi Jews in the 1940s, primarily among the younger population, especially as a result of the impact it had on hopes of long term integration into Iraqi society. In the direct aftermath of the Farhud, many joined the Iraqi Communist Party in order to protect the Jews of Baghdad, yet they did not want to leave the country and rather sought to fight for better conditions in Iraq itself. At the same time the Iraqi government that had taken over after the Farhud reassured the Iraqi Jewish community, and normal life soon returned to Baghdad, which saw a marked betterment of its economic situation during World War II.
