The Bolsheviks.

It's a slogan of the early Bolsheviks.

This phrase is associated with Vladimir Lenin, the Bolshevik Party and the Russian Revolution, specifically the October Revolution of 1917. The phrase was used before the revolution on posters designed to rally around the Bolsheviks, because it meant ending Russia's participation in World War 1, and end to food shortages and an end to unfair distribution of land among the wealthy.
