Communist Party UMSPR

The Communist Party of Magisteria (CPM) (French: Parti Communiste du Magistère; PCM), officially known as the Communist Party of the Socialist Republics of United Magisteria (CPSRUM) (French: Parti Communiste du Républiques Socialistes du Magistère Uni; PCRSMU), is the founding and sole legal party of the Socialist Republics of United Magisteria. Founded in 1946 by Martin Jean, the CPM became the ruling party shortly after the declaration of the Union in 1946.

Although Magisteria is a one-party state, some other institutional popular front parties are permitted to exist in alliance with the CPM in a similar fashion to East Germany's National Front; these parties included the Liberal Socialist Party, Green Workers' Party, the Pirate Party, and the Centre Party.

The CPM is organized on the basis of democratic centralism, a principle conceived by Russian Marxist revolutionary Vladimir Lenin. The CPM is committed to communism and participates in the annual International Meeting of Communist and Workers' Parties. The party is also known for its advocacy of 'Communism with Magisterian characteristics', as well as Jeanism, Marxism–Leninism, ideas from the French Revolution, press freedom, and anti-corruption.
