May 19, 1965
Mapai, a socialist-Zionist political party established in 1930, is the dominant party in the Jewish community in mandate Palestine as well as in the early years of the state. Achdut Ha’Avodah, another socialist-Zionist political party established in 1919, maintains a similar political agenda. In 1965, as an answer to right wing parties uniting into stronger political entities that threaten left of center political supremacy in the Knesset, the two parties join forces, taking 45 seats in the 6th Knesset in November 1965. They come to be known as the Labor Alignment.
