David Ben-Gurion (/bɛn ˈɡʊəriən/ ben GOOR-ee-ən; Hebrew: דָּוִד בֶּן־גּוּרִיּוֹן [daˈvid ben ɡuʁˈjon] ; born David Grün; 16 October 1886 – 1 December 1973) was the primary national founder and first prime minister of the State of Israel. As head of the Jewish Agency from 1935, and later president of the Jewish Agency Executive, he was the de facto leader of the Jewish community in Palestine, and largely led the movement for an independent Jewish state in Mandatory Palestine.
Born in Płońsk, then part of Congress Poland, to Polish Jewish parents, he immigrated to the Palestine region of the Ottoman Empire in 1906. Adopting the name of Ben-Gurion in 1909, he rose to become the preeminent leader of the Jewish community in British-ruled Mandatory Palestine from 1935 until the establishment of the State of Israel in 1948, which he led until 1963 with a short break in 1954–55. Ben-Gurion's interest for Zionism developed early in his life, leading him to become a major Zionist leader, and the executive head of the World Zionist Organization in 1946.
