Introduced to Zionism by his father, Ben-Gurion immigrated to Palestine, then part of the Ottoman Empire, in 1906, hoping to fulfill the Zionist aspiration of building a Jewish state in historic Israel. Expelled by the Ottomans at the outbreak of World War I (1914-18), he traveled to New York, where he married. Following the issuance of the Balfour Declaration, he joined the British army's Jewish Legion and returned to the Middle East. In the 1920s and '30s he led several political organizations, including the Jewish Agency, world Zionism's highest directing body. As Britain became more sympathetic to the interests of the Palestinian Arabs, thereafter restricting Jewish immigration to Palestine, he called on the Jewish community to rise against Britain. However, he again called for Jews to support the Allies during World War II (1939-45), while continuing the clandestine immigration of Jews to Palestine. On the establishment of the State of Israel (1948), he became prime minister and minister of defense. He succeeded in fusing the underground Jewish militias that had fought the British into a national army, which he used successfully to defend against Arab attacks. Unpopular with Britain and the U.S., he found an ally in France then embroiled in its own war in the Arab world which helped arm Israel in the period leading to the Suez Crisis (1956). He retired from the premiership in 1963 and from the Knesset (parliament) in 1970. See also Arab-Israeli wars
