Initially the party was known as Communist Movement of Spain (Movimiento Comunista de España).

MCE attempted to unify with the Communist Unification of Spain (UCE), but that relation was later broken.

In the 1983 regional assembly elections EUPV contested as part of the Valencian People's Union (UPV).

Later as MC disintegrated, MCPV and LCR militants in Valencia formed the collective Revolta.

In 1991, MC merged with LCR and formed the Alternative Left (Izquierda Alternativa), which had a brief existence.
