With increasing Jewish immigration during the British administration, friction between Arabs and Jews in Palestine increased. On 1 May 1921, the Jaffa riots resulted in the deaths of 48 Arabs and 47 Jews and injuries to 146 Jews and 73 Arabs. In the wake of this violence, many Jews left Jaffa for Tel Aviv. The population of Tel Aviv increased from 2,000 in 1920 to around 34,000 by 1925.
