Marxist Unification Movement
Marxist Unification Movement was a political group in Catalonia, Spain. MUM was founded in 1977, during the Spanish transition to democracy, by a group that had left the Socialist Party of National Liberation of the Catalan Countries in 1976 and the Col·lectiu Combat, a splinter group of the Catalan National Front.
MUM differed from other radical Catalan separatists in its willingness to participate in the Spanish electoral process. In the 1977 elections, MUM formed part of the Popular Unity Candidature for Socialism, which launched Salvador Casanova as its main candidate. After the elections, MUM merged with the Party of Labour of Catalonia and formed the Catalan Workers Bloc.
