The Internationale “Интернационал” – Russian Version
Originally composed by Pierre de Geyter in 1888, it has been the standard for most socialist and left wing movements with the Second Internationale adopting it as their official anthem with anarchists, socialists, communists and other leftists celebrating its use.
The USSR before the 1930’s also used this as their official anthem with the lyrics being translated into multiple different languages.
