separating the Marxists from the more moderate leftists, Ein Harod and Tel Yosef ceased their close cooperation. Permanent location In 1930, when the collective moved to a permanent location at the foot of Kumi Hill, the kibbutz had 239 members. The village played an important role in the defence of the area during the 1936–1939 Arab revolt in Palestine, known by the Jews of the era as "the disturbances," during which it was the base of Orde Wingate's Special Night Squads. In 1945 the Haganah had a small prison there in which they detained members of the Irgun during the Season. However, on 29 June 1946, as part of Operation Agatha, the British army occupied the kibbutz by force. By 1947 it had a population of 1,120. Ideological split In 1952, in the wake of ideological differences between supporters of the two main socialist parties, Mapai and Mapam, the kibbutz split, creating two separate kibbutzim: Ein Harod (Ihud), affiliated with Mapai and belonging to Ihud HaKvutzot veHaKibbutzim; and Ein Harod (Meuhad), affiliated with Mapam and belonging to HaKibbutz HaMeuhad. Today both kibbutzim belong to the United Kibbutz Movement. Museums Mishkan Museum of Art (full name: Ein Harod Art Museum) is one of the first art museums in Israel. The museum was founded in 1937 as an "art corner" during the early years of the kibbutz in the belief that culture and art were among the essential components of a society. The artworks were initially displayed in the art studio owned by Haim Atar, a small wooden hut. A new, imposing, museum building, designed by an architect , was inaugurated in 1948. During construction of the museum, the 1952 Mapai/Mapam split happened, but the museum was preserved as the joint institution for the split kibbuzim. The museum was declared as a "heritage site" by the Council for Conservation of Heritage Sites in Israel. houses a collection of archaeology and artifacts related to local history of the area.
