White power skinheads, also known as racist skinheads and neo-Nazi skinheads, are members of a neo-Nazi, white supremacist and antisemitic offshoot of the skinhead subculture. Many of them are affiliated with white nationalist organizations and some of them are members of prison gangs. The movement emerged in the United Kingdom between the late 1960s and the late 1970s, before spreading across Europe, Russia and North America in the 1980–1990s.
