The Red Army Faction, also known as the Baader–Meinhof Group or Baader–Meinhof Gang, was a West German far-left militant group founded in 1970 and active until 1998, considered a terrorist organisation by the West German government. The RAF described itself as a communist and anti-imperialist urban guerrilla group. It was engaged in armed resistance against what it considered a fascist state. Members of the RAF generally used the Marxist–Leninist term "faction" when they wrote in English. Early leadership included Andreas Baader, Ulrike Meinhof, Gudrun Ensslin, and Horst Mahler.
