Ben-Zvi settled in Palestine at the beginning of 1907 and was a Po’alei Zion delegate to the Eighth Zionist Congress held that year in The Hague.
Along with Rahel Yanait, whom he later married, BenZvi participated in the founding of the Ha-Shomer Jewish defense organization.
In 1910, Ben-Zvi, Rahel Yanait, and Ze’ev Ashur founded the first Hebrew socialist periodical “Ahdut” (Unity) in the country.
Subsequently deported along with David Ben-Gurion, they founded the He-Halutz (Pioneer) movement of America to prepare young Jews for settlement in Palestine, and established branches in many cities.
They returned to Palestine in 1918 as soldiers of the Jewish Legion in the British Royal Fusiliers. During the Arab riots in Jerusalem in the 1920s, Ben-Zvi was active in the ranks of the Haganah (voluntary Jewish self-defense organization).
With the establishment of the Va’ad Le’ummi (National Committee) in 1920, Ben-Zvi was elected to its leadership, first as a member, later as chairman (1931), and finally as president in 1945.
Upon the passing of Chaim Weizmann, Ben-Zvi was elected President of the State on December 10, 1952, and in 1957 was returned by the Knesset to that office for five more years. In 1962, he was elected president for a third term and died in office on April 23, 1963.
Ben-Zvi headed the Institute for the Study of Oriental Jewish Communities in the Middle East, which he founded in 1948 and was later named the Ben-Zvi Institute. His scholarly works were devoted mainly to research on communities and sects (Samaritans, Karaites, Jewish communities in Asia and Africa, etc.) and the geography of the land of Israel, its ancient populations, antiquities, and traditions.
