Mapei resulted from the 1930 merger between the main prestate Labor Zionist parties, Ahdut HaAvoda and HaPoel HaTzair. In 1920 the twoEparties together founded the Histadrut. In 1944 a small left-wing kibbutz-based faction seceded from Mapai and reconstituted itself as Andut HaAvoda-Poalei Tziyyon (Unity of Labor-Workers of Zion). Nevertheless, Mapei became the dominant party in the Yishuv and later in Israel; after 1968 it was the dominant faction in the Labor Party.
