Although Mapam was a workers' party and a natural partner for Mapai, in 1949 Ben-Gurion preferred to establish a coalition with the religious parties. Mapam remained in the opposition, entering the government for the first time only after the elections for the Third Knesset in 1955. Mapam members Mordechai Bentov and Yisrael Barzilai were appointed Minister of Development and Minister of Health, respectively. Mapam joined the coalition headed by Mapai after the 1959 elections as well, and its two Ministers continued to hold their portfolios. The party moved to the opposition in the course of the Fifth Knesset (1961–1965), but returned to the coalition in early 1966. Bentov and Barzilai once again served as Ministers and held the Housing and Health portfolios.
