, 1936 During the
Spanish transition to democracy, the POUM was legalized in 1977. This led to a split in the party, with one faction opposing formal legalization, calling for a boycott of the
1977 general election and demanding the immediate restoration of the republic. The legalized party participated in the election as part of the
Front for Workers' Unity (FUT), a coalition of parties and organizations to the left of the PCE which won 0.22% of the nationwide vote. The election result led to a crisis for the POUM as well as for most parties to the left of the PCE, from which it was not able to recover. The POUM continued to exist as a small party with an office in Barcelona and a monthly newspaper,
La Batalla, calling for cooperation among the various far-left parties, but an attempted merger with
Communist Action and the Collective for Marxist Unification failed during a "Unification Congress" in 1978. After this setback, the POUM decided not to participate in the
1979 elections. POUM branches in several cities became part of local coalitions and unification attempts with various far-left groups. In 1980, the POUM made its last electoral efforts, supporting
Herri Batasuna in the Basque country and participating in the
Left Bloc for National Liberation (BEAN - Unitat Popular) coalition in the Catalan parliamentary election, but the party was disintegrating.
La Batalla ceased publication in May 1980, marking the end of the POUM as an organized party, though it was never officially dissolved. As a last remnant, the
Valencia branch remained active until 1981. Former members of the POUM formed the Fundación Andreu Nin (Andreu Nin Foundation) to preserve the heritage of their party and ideological current. ==Cultural references==
