"Solidarity Forever" is a trade union anthem written in 1915 by Ralph Chaplin promoting the use of solidarity amongst workers through unions. It is sung to the tune of "John Brown's Body" and "The Battle Hymn of the Republic". Although it was written as a song for the Industrial Workers of the World (IWW), other union movements, such as the AFL–CIO, have adopted the song as their own. The song has been performed by musicians such as Utah Phillips, Pete Seeger, and John Darnielle. It was redone by Emcee Lynx and The Nightwatchman. It is still commonly sung at union meetings and rallies in the United States, Australia, and Canada, and has also been sung at conferences of the Australian Labor Party and the Canadian New Democratic Party. This may have also inspired the hymn of the consumer cooperative movement, "The Battle Hymn of Cooperation", which is sung to the same tune.
