Chaim Azriel Weizmann was a Russian-born biochemist, Zionist leader and Israeli statesman who served as president of the Zionist Organization and later as the first president of Israel. He was elected on 16 February 1949, and served until his death in 1952. Weizmann was instrumental in obtaining the Balfour Declaration and later convincing the United States government to recognize the newly formed State of Israel.

Zionism is a nationalist movement that emerged in Europe in the late 19th century aiming for the establishment of a homeland for the Jewish people, particularly in Palestine, a region roughly corresponding to the Land of Israel in Jewish tradition. Following the establishment of the State of Israel, Zionism became an ideology that supports the development and protection of Israel as a Jewish state. It has also been described as Israel's national or state ideology.
