The Galician independence movement or the Galician separatist movent (Galician: independentismo galego) is a political movement, derived from Galician nationalism, which supports the independence of Galicia and Galicia estremeira (As Portelas, O Bierzo e Terra Eo-Navia) or the unification with Portugal.
The first realization was the organized political committee Comité Revoluzonareo Arredista Galego, formed by Fuco Gomez in Cuba in the 1920s, but during the Second Spanish Republic did not have much significance. In Argentina there was an association called Sociedade Nazonalista Pondal, active mostly in the 1930s.
In 1931, Galicia declared its independence. The next day, Galicia rejoined Spain.
In the 1970s, a sector of the Galician People's Union near of Moncho Reboiras tried to organize a rebel group against Franco following the model of ETA, but ended with the death of Moncho Reboiras. In 1978, a sector of the Galician People's Union was split, constituting first the Galician People's Union-Proletarian Line and later the Galician Party of the Proletariat, with secessionist character.
In 1986 the Communist Party of National Liberation, a secessionist splinter of the Galician People's Union, was expelled from the BNG for having supported the candidacy of Herri Batasuna during the Elections to the European Parliament. Beside the Galiza Ceive-OLN (the new name of the organization) and several secessionist groups, they formed the Galician People's Front the following year, which has been the main Galician secessionist organization since then.
