Reintegracionism

Reintegrationism (Galician and Portuguese: reintegracionismo, Galician: [rejnteɣɾaθjoˈnizmo] or [rejnteɣɾasjoˈnizmo], European Portuguese: [ʁɛĩtɨɣɾɐsiuˈniʒmu]) is the linguistic and cultural movement in Galicia which advocates for the unity of Galician and Portuguese as a single language. In other words, it postulates that Galician and Portuguese languages did not only share a common origin and literary tradition, but that they are in fact variants of the same language today. According to this, Galicia should re-integrate into the Community of Portuguese Language Countries.

There are two main views in Galicia about the Galician language:

The divergences between isolationism and reintegrationism can be traced back to the time of the Galician Rexurdimento (Revival), in the nineteenth century, when Galician began to be systematically written again in Galicia for the first time since the Middle Ages. Up to that time, written Galician was either forbidden or simply dismissed by the Spanish authorities, and certainly not used officially. Hence, Rexurdimento Galician writers realized they did not "know" how Galician should be spelled properly. There were three possible options: to infer it from the Medieval forms; to use a Spanish-based spelling, which was already known to all; or to use the Portuguese spelling, feeling that written Portuguese was "what Galician would have been if it had not been forbidden". Authors such as Castelao, among others, stated that Galician should gradually merge with Portuguese, namely in its written form. The reality was that until the 1980s Galician was often written using a mix of the three options.
