1920s

With the commitment to establishing a national home for the Jewish people in Palestine, the creation of the British Mandate in Palestine after the end of the first world war would allow for large-scale Jewish immigration. This would be accompanied by the development of a separate Jewish controlled sector of the economy which was supported with large amounts of capital from abroad. The more ardent Zionist ideologues of the Second Aliyah would become the leaders of the Yishuv starting in the 1920s and believed in the separation of Jewish and Arab economies and societies. During this period, the exclusionary nationalist ethos would grow to overpower the socialist ideals that the Second Aliyah had arrived with.

Amin al-Husseini, the leader of the Palestinian Arab national movement, immediately marked Jewish national movement and Jewish immigration to Palestine as the sole enemy to his cause, initiating large-scale riots against the Jews as early as 1920 in Jerusalem and in 1921 in Jaffa. Among the results of the violence was the establishment of the Jewish paramilitary force Haganah. In 1929, a series of violent riots resulted in the deaths of 133 Jews and 116 Arabs, with significant Jewish casualties in Hebron and Safed, and the evacuation of Jews from Hebron and Gaza.
