The concept of Galicianism first appeared in the mid-nineteenth century. At that time in history it was initially known as "provincialism". Soon it was referred to as regionalism. This was a reaction to the increased centralization of the Spanish State which attempted to eradicate internal administrative, and to some point cultural, differences within the country. The term Galicianism as such was coined after the establishment of the Irmandades da Fala, in 1916, and the apparition of modern Galician nationalism. The Irmandades da Fala was an organization hosting members from both the lower-middle-class and intellectuals. This organization was led by Antón Vilar Ponte. Within the next decade, this organization was strengthened by two groups: the nationalists, led by the Partido Galeguista of Castelao, and the federalist republicans of ORGA. ORGA was directed by Santiago Casares and Antón Vilar.
The foundation of the Editorial Galaxia in 1950, publishing house promoting Galician culture and Galician language, was a visible act of resistance. Clandestine organizations supporting the cause of Marxism flourished in the 1950s and 1960s following the example of Editorial Galaxia and taking advantage of a timid relaxation of the dictatorial regime. Those new organizations and movements openly labelled themselves as nationalist, seeing themselves as the natural heirs of the early Galicianists. All those organizations would claim Alfonso Daniel Rodríguez Castelao's classic work, Sempre en Galiza, as the ideological cornerstone for Galician contemporary nationalism and even for their own foundational principles.
Contemporary Galicianism
With the end of the dictatorship in 1975 and the passing of a new constitution in 1978, Galicianism was further strengthened up to the point that today the vast majority of political forces in Galicia call themselves Galicianist, whether they are nationalist or not, left wing or right wing. For example, unlike in other Spanish autonomous communities, the conservative People's Party of Galicia includes Galicianism as one of its ideological principles. Even the Spanish Socialist Workers' Party has a strong regional flavour in Galicia, not to mention the actual main Galician nationalist party, the Galician Nationalist Bloc. A possible explanation for this is that Galician identity is so embedded in Galicians that any political party willing to participate in elections must at least show some degree of interest in the promotion of Galicianism, but it may range greatly, from moderate regionalism to outright claims for independence.
