On 20 May 1944 a group known as Faction B split from Mapai adopting the Ahdut HaAvoda name from fourteen years earlier. This group was pro-Soviet, and rejected any territorial compromise. Many of its members came from HaKibbutz HaMeuhad, the Mapai kibbutz organization. They held a majority of the senior posts in the Haganah and in particular in the Palmach. Key leaders were Israel Galili and Yigal Allon. Others with close ties were David Elazar, Yitzhak Hofi, Avraham Adan and Yitzhak Rabin.
