Hope for return to the land of Israel is embodied in the content of the Jewish religion (see Kibbutz Galuyot.) Aliyah, the Hebrew word meaning "ascending" or "going up", is the word used to describe religious Jewish return to Israel, and has been used since ancient times.
Following Jewish Enlightenment however, Reform Judaism dropped many traditional beliefs, including aliyah, as incompatible with modern life within the Diaspora. Later, Zionism re-kindled the concept of aliyah in an ideological and political sense, parallel with traditional religious belief; it was used to increase Jewish population in the Holy Land by immigration and it remains a basic tenet of Zionist ideology.
Support for aliyah does not always equal immigration however, as a majority of the world Jewish population remains within the Diaspora. Support for the modern Zionist movement is not universal and as a result, some religious Jews as well as some secular Jews, do not support Zionism. Non-Zionist Jews are not necessarily anti-Zionists, although some are. Generally however, Zionism does have the support of the majority of the Jewish religious organizations, with support from segments of the Orthodox movement, and most of the Conservative, and more recently, the Reform movement.
Many Hasidic rabbis oppose the creation of a Jewish state. The leader of the Satmar Hasidic group, Rabbi Joel Teitelbaum's book, VaYoel Moshe, published in 1958, expounds one Orthodox position on Zionism, based on a literal form of midrash (biblical interpretation). Citing to Tractate Kesubos 111a of the Talmud Teitelbaum states that God and the Jewish people exchanged three oaths at the time of the Jews' exile from ancient Israel, forbidding the Jewish people from massively immigrating to the Land of Israel, and from rebelling against the nations of the world.
