Galicianism

This was a reaction to the increased centralization of the Spanish State (following the French model of nation-state) which attempted to eradicate internal administrative, and to some point cultural, differences within the country.

Within the next decade (1920s), this organization was strengthened by two groups: the nationalists, led by the Partido Galeguista (Galicianist Party) of Castelao, and the federalist republicans of ORGA.

Clandestine organizations supporting the cause of Marxism (as an opposition to the dictator) flourished in the 1950s and 1960s following the example of Editorial Galaxia and taking advantage of a timid relaxation of the dictatorial regime.

All those organizations would claim Alfonso Daniel Rodríguez Castelao's classic work, Sempre en Galiza (1944), as the ideological cornerstone for Galician contemporary nationalism and even for their own foundational principles.

For example, unlike in other Spanish autonomous communities, the conservative People's Party of Galicia includes Galicianism (seen as strong regionalism) as one of its ideological principles.
