Hapoel Hatzair (The Young Worker) was a Zionist group which was active in Palestine from 1905 until 1930. They were founded by A.D. Gordon, Yosef Ahronowitz, Yosef Sprinzak and followed a non-Marxist, Zionist, socialist agenda. In accordance with A.D. Gordon's beliefs, Hapoel Hatzair was an extremely pacifist and anti-militarist group and sought to establish a Jewish foothold in Palestine through the conquest of labor and land.
Hapoel Hatzair was formed in 1905 by the second wave of Jewish immigrants to Palestine, who came between 1904 and 1914. The new immigrants sought to build a Jewish socialist homeland in Palestine and formed two groups in order to accomplish this: Poale Zion (Workers of Zion) and Hapoel Hatzair. In 1905, Hapoel Hatzair consisted of only 90 members. By 1910, the group had grown, although not to huge numbers. There were only 500 members of Hapoel Hatzair and Poale Zion combined. Hapoel Hatzair's commitment to the conquest of labour created a group that was dedicated to the creation of new Jewish agricultural communities. Hapoel Hatzair settled land bought from Arab effendis (landowners) by the Jewish National Fund in accordance with socialist principles.
When Ahdut HaAvoda was formed in 1919, Hapoel Hatzair decided not to join, although some members did leave to join Ahdut HaAvoda. Leaders of Hapoel Hatzair felt that the Labor Union, which had strong political ambitions, would dominate any united group and they did not want this to cause them to compromise Hapoel Hatzair's role as the conscience of the labor movement. By not joining Ahdut HaAvoda, Hapoel Hatzair was forced to enter into the urban worker movement. While powerful among agricultural workers, Hapoel Hatzair did not have a large following in the towns; however, they did have a significant following among writers, teachers, and other intellectuals, which although not helpful in the political arena, did bring more prestige to the group.
Over time, members of Hapoel Hatzair and Ahdut HaAvoda realized that they were duplicating work. As both groups existed as a labor group as well as a political party, they had separate employment exchanges, mutual aid organisations, cultural and social clubs, and sickness funds. In 1920, it was suggested that unite. This led to the formation of the Histadrut, which was a single workers organization to control labor. While these parties had united their labor organizations into the Histadrut, they continued to fight for dominance of this group. In the first election in 1924, Hapoel Hatzair won 27 seats, which was second only to Ahdut HaAvoda, which held 38. While Ahdut HaAvoda was larger, Hapoel Hatzair was more powerful; In 1921 Yosef Sprinzak of Hapoel Hatzair was the first member of the labor movement to be elected to the Zionist Executive.
