 Those new organizations and movements openly labelled themselves as nationalist, seeing themselves as the natural heirs of the early Galicianists (for example the Galician People's Union (UPG) was founded by some old Galicianists among other new members).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.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.
