The Fifth Aliyah
The Fifth Aliyah brought in over 250,000 Jews to Palestine during the 1930s, nearly doubling the population of the Yishuv. Mostly middle-class Jews, they tended to settle in the bigger cities like Tel Aviv and Haifa, and in doing so dramatically boosted the Palestinian economy. A significant portion, around 60,000, of these immigrants came from Germany as part of the Ha’avara (Transfer) Agreement with the Nazis, in which Jews were allowed to leave in exchange for their wealth remaining in Germany. The huge influx of Jews during the 1930s also increased tensions with the Arabs, and contributed to the Arab Revolt of 1936-39.
