Langenhagen is a town in the Hanover district of Lower Saxony, Germany.

Ulrike Marie Meinhof was a German left-wing 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".
