 The growth of the Jewish community of Palestine, which was known as the Yishuv, was disrupted by the outbreak of World War I in 1914.During the war, many Jews were expelled from Palestine by the Ottoman authorities as enemy nationals, since they had immigrated from countries now at war with the Ottoman Empire.In 1917, the Ottoman authorities carried out the Tel Aviv and Jaffa deportation, expelling the entire Jewish civilian populations of Tel Aviv and Jaffa.
