In the 1920s and 1930s Rabbi Abraham Isaac Kook (the first Chief Rabbi of Palestine) and his son Rabbi Zevi Judah Kook saw great religious and traditional value in many of Zionism's ideals, while rejecting its anti-religious undertones. They taught that Orthodox (Torah) Judaism embraces and mandates Zionism's positive ideals, such as the ingathering of exiles, and political activity to create and maintain a Jewish political entity in the Land of Israel. In this way, Zionism serves as a bridge between Orthodox and secular Jews.
While other Zionist groups tended to moderate their nationalism over time, the gains from the Six-Day War have led religious Zionism to play a significant role in Israeli political life. Now associated with the National Religious Party and Gush Emunim, religious Zionists have been at the forefront of Jewish settlement in the West Bank and efforts to assert Jewish control over the Old City of Jerusalem.
Major aspects of the Zionist idea are represented in the Israeli Declaration of Independence:
The Land of Israel was the birthplace of the Jewish people. Here their spiritual, religious and political identity was shaped. Here they first attained to statehood, created cultural values of national and universal significance and gave to the world the eternal Book of Books.
After being forcibly exiled from their land, the people kept faith with it throughout their Dispersion and never ceased to pray and hope for their return to it and for the restoration in it of their political freedom.
Impelled by this historic and traditional attachment, Jews strove in every successive generation to re-establish themselves in their ancient homeland. In recent decades they returned in their masses.
