Washington, DC protests against the war in Vietnam (Mayday), 1971
The Mayday protest was a series of large-scale demonstrations against the involvement of the United States in the Vietnam War. It happened in 1971 in Washington, DC from May 1 to May 3 and diminished within several days. The goal was to shut down the federal government offices, because the Mayday Tribe (a largely young and more militant segment of the U.S. anti-war movement) had given an ultimatum to the Nixon Administration that this would happen if it did not end the war.
