Ulrike Meinhof, German far-left terrorist, co-founder of the Red Army Faction, journalist (died 1976)

Ulrike Marie Meinhof was a German left-wing militant, journalist and founding member of the Red Army Faction (RAF) in West Germany, commonly referred to in the press as the "Baader-Meinhof gang". She is the reputed author of The Urban Guerilla Concept (1971). The manifesto acknowledges the RAF's "roots in the history of the student movement"; condemns "reformism" as "a brake on the anti-capitalist struggle"; and invokes Mao Zedong to define "armed struggle" as "the highest form of Marxism-Leninism".

Far-left politics are politics further to the left on the political spectrum than the standard political left. The term encompasses a variety of ideologies, from socialism to anarchism. In certain instances—especially in the news media—far left has been associated with some forms of authoritarianism, anarchism, communism, and Marxism, or are characterized as groups that advocate for revolutionary socialism and related communist ideologies, or anti-capitalism and anti-globalization. Far-left terrorism consists of extremist, militant, or insurgent groups that attempt to realize their ideals through political violence rather than using democratic processes.

Terrorism, in its broadest sense, is the use of violence against non-combatants to achieve political or ideological aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants. There are various different definitions of terrorism, with no universal agreement about it. Different definitions of terrorism emphasize its randomness, its aim to instill fear, and its broader impact beyond its immediate victims.

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.
