Not until the 20th century did groups of burakumin begin organizing for their cause; in 1922 a national organization, Suiheisha (Organization of Levelers), was created, and it engaged in various school boycotts, tax revolts, and other protests until its disbandment in 1941. After World War II, in 1946, a more militant and politically active organization was formed: the Buraku Kaihō Zenkoku Iinkai (All-Japan Committee for Buraku Liberation), which in 1955 was renamed Buraku Kaihō Dōmei (Buraku Liberation League). Its leftist orientation, however, alienated more conservative burakumin leaders. Thus in 1960 a rival national organization, Dōwakai (Society for Integration), was founded; it came to be led by Liberal Democratic politicians, some of whom were elected to the national Diet. A third organization, the Zenkoku Buraku Kaihō Undō (All-Japan Buraku Liberation Movement), was formed in 1976.
