In the United States, the Revolutionary Youth Movement (RYM) was the section of Students for a Democratic Society (SDS) that opposed the Worker Student Alliance of the Progressive Labor Party (PLP). Most of the national leadership of SDS joined the RYM in order to oppose PLP's party line and what they alleged to be its attempted takeover of the SDS leadership structure, particularly at the 1969 SDS convention in Chicago. In the 1969 fragmentation of SDS, RYM departed the convention hall and declared itself the "real SDS" in a new space across the street. * Revolutionary Student Brigade
