Radical lesbianism is a lesbian movement that challenges the status quo of heterosexuality and mainstream feminism. It arose in part because mainstream feminism did not actively include or fight for lesbian rights. The movement was started by lesbian feminist groups in the United States in the 1950s and 1960s. A Canadian movement followed in the 1970s, which added momentum. As it continued to gain popularity, radical lesbianism spread throughout Canada, the United States, and France. The French-based movement, Front des Lesbiennes Radicales, or FLR, organized in 1981 under the name Front des Lesbiennes Radicales. Other movements, such as Radicalesbians, have also stemmed off of the larger radical lesbianism movement. In addition to being associated with social movements, radical lesbianism also offers its own ideology, similar to how feminism functions in both capacities. Source: Wikipedia (en)
