inheritance of the Children of Israel based on the Torah, particularly the books of Genesis and Exodus, as well as on the later Prophets. According to the Book of Genesis, Canaan was first promised to Abraham's descendants; the text is explicit that this is a covenant between God and Abraham for his descendants. The belief that God had assigned Canaan to the Israelites as a Promised Land is also conserved also in Christian and Islamic traditions. Among Jews in the Diaspora, the Land of Israel was revered in a cultural, national, ethnic, historical, and religious sense. They thought of a return to it in a future messianic age. Return to Zion remained a recurring theme among generations, particularly in Passover and Yom Kippur prayers, which traditionally concluded with "Next year in Jerusalem", and in the thrice-daily Amidah (Standing prayer). The biblical prophecy of Kibbutz Galuyot, the ingathering of exiles in the Land of Israel as foretold by the Prophets, became a central idea in Zionism. Pre-Zionist initiatives In the middle of the 16th century, the Portuguese Sephardi Joseph Nasi, with the support of the Ottoman Empire, tried to gather the Portuguese Jews, first to migrate to Cyprus, then owned by the Republic of Venice, and later to resettle in Tiberias. Nasi—who never converted to Islam—eventually obtained the highest medical position in the empire, and actively participated in court life. He convinced Suleiman I to intervene with the Pope on behalf of Ottoman-subject Portuguese Jews imprisoned in Ancona. Between the 4th and 19th centuries, Nasi's was the only practical attempt to establish some sort of Jewish political center in Palestine. In the 17th century Sabbatai Zevi (1626–1676) announced himself as the Messiah and gained many Jews to his side, forming a base in Salonika. He first tried to establish a settlement in Gaza, but moved later to Smyrna. After deposing the old rabbi Aaron Lapapa in the spring of 1666, the Jewish community of Avignon, France prepared to emigrate to the new kingdom. The readiness of the Jews of the time to believe the messianic claims of Sabbatai Zevi may be largely explained by the desperate state of Central European Jewry in the mid-17th century. The bloody pogroms of Bohdan Khmelnytsky had wiped out one-third of the Jewish population and destroyed many centers of Jewish learning and communal life. In the early 19th century, a group of Jews known as the
