The Weather Underground was a radical left-wing group active in the United States from 1969 to 1977. Emerging from the anti-Vietnam War and civil rights movements, it was founded by members of the Students for a Democratic Society who believed that more aggressive actions were necessary to combat U.S. imperialism. The group aimed to overthrow the U.S. government, which they viewed as oppressive and imperialistic. To protest the Vietnam War and other social injustices, the Weather Underground carried out a series of bombings targeting government buildings and banks, as well as creating this manifesto that marked a large defeat for U.S. imperialism
