United front

A united front is an alliance of groups against their common enemies, figuratively evoking unification of previously separate geographic fronts and/or unification of previously separate armies into a front (formation); the name often refers to a political and/or military struggle carried out by revolutionaries, especially in revolutionary socialism or communism. The basic theory of the united front tactic among socialists was first developed by the Comintern, an international communist organization created by communists in the wake of the 1917 Bolshevik Revolution.

According to the thesis of the 1922 4th World Congress of the Comintern:

“The united front tactic is simply an initiative whereby the Communists propose to join with all workers belonging to other parties and groups and all unaligned workers in a common struggle to defend the immediate, basic interests of the working class against the bourgeoisie.”

The united front allowed workers committed to the revolutionary overthrow of capitalism to struggle alongside non-revolutionary workers. Through these common struggles, revolutionaries sought to win other workers to revolutionary socialism. The united front perspective is also used in contemporary and non-Leninist perspectives.

According to Russian activist Leon Trotsky, the roots of the united front go back to the practice of the Bolshevik Party in the 1917 Russian Revolution. The Comintern generalised this experience among the fledgling Communist parties that were established or grew significantly during the years following 1917. The theory of the united front was elaborated at the third and fourth congresses of the Comintern, held from November 5 to December 5, 1922.

Revolutionary socialists represented a minority in the working class, and the united front offered a method of working with large numbers of non-revolutionary workers and simultaneously winning them to revolutionary politics. The united front strategy was used by leaders in the period after the initial revolutionary tide following 1917 began to ebb. According to leaders of the Comintern, the shift from offensive to defensive struggles by workers strengthened the desire for united action within the working class. The leaders hoped that the united front would allow the revolutionaries to win a majority inside the class:
