What happened to the communist party in World War 1?

During World War I, the communist movement gained momentum, particularly in Russia. The war exacerbated social and economic discontent, leading to widespread unrest. In 1917, the Bolshevik Party, led by Vladimir Lenin, capitalized on this discontent, ultimately overthrowing the provisional government in the October Revolution and establishing a communist regime. The war's end and the subsequent Russian Civil War solidified the Bolsheviks' control, leading to the formation of the Soviet Union in 1922.
