During the 1960s, the various unaffiliated Mattachine Societies, especially the Mattachine Society in San Francisco and MSNY, were among the foremost gay rights groups in the United States, but beginning in the middle 1960s and, especially, following the Stonewall riots of 1969, they began increasingly to be seen as too traditional, and not willing enough to be confrontational. Like the divide that occurred within the Civil Rights Movement, the late 1960s and the 1970s brought a new generation of activists, many of whom felt that the gay rights movement needed to endorse a larger and more radical agenda to address other forms of oppression, the Vietnam War, and the sexual revolution. Several unaffiliated entities that went under the name Mattachine eventually lost support or fell prey to internal division.
