The Herut movement was founded in 1948 and succeeded the Irgun organization, the military arm of the Revisionist movement (created by Jabotinsky) during the Yishuv period. It opposed Mapai in its vision for the Land of Israel.

Established in 1930, the Mapai party resulted from the union of two parties: Ahdut HaAvoda and HaPoel HaTzair. The left union was not complete, as Hashomer Hatzair and Poalei Zion Smol (Left) were left out of the union.

David Ben-Gurion (born David Grun) was an Israeli politician and the first Prime Minister of the State of Israel.

Ahdut Ha'Avoda was a socialist Zionist party. It was founded in 1919 as a union of the "Poalei Zion" party headed by David Ben-Gurion and the "non-partisan" workers.
