An ancient community: There was already an indigenous Jewish population in Palestine during the Ottoman Empire and before. Its members were concentrated principally in the holy cities of Jerusalem, Safed, Tiberias and Hebron. Nonetheless, the Jewish presence in Palestine, prior to the establishment of the State of Israel, had fluctuated through time, with various communities appearing and disappearing. Regardless, in 1880, before immigration began, Palestine’s Jewish population numbered about 25,000, and had been deeply rooted there for several generations.
The beginning of Zionism and immigration: The beginning of modern, national-minded Jewish immigration coincides with the foundation of the modern Zionist movement. Zionism as a political movement is conventionally dated to 1882. Small groups of Jews dispersed through Europe began to cooperate to establish agricultural colonies in historical Palestine. These groups met officially for the first time in 1897, for the first Zionist conference, in Basel, Switzerland.
