Ха-Поэль ха-Цаир
In 1932, Poale Zion's world federation merged with Hitahdut Olamit, the World Union of Hapoel Hatzair and Zeirei Zion (which had been formed in 1920), to create Ihud Olami, the World Union of Zionists-Socialists. In this period, several well-known Zionist leaders and politicians were active in Poale Zion, including Ben-Gurion, Ben-Zvi, kibbutz movement leader Yitzhak Tabenkin, Jewish Agency Executive member Shlomo Kaplansky, and future Israeli politicians Moshe Sharett and Dov Hoz.
