During the 19th century a revival movement arose. This movement defended the Galician language, and created a provisional norm, with a Castilian orthography and many loanwords. When autonomy was granted, a norm and orthography (based in "rexurdimento" writers) (Galician literature) for a Galician language was created. This norm is taught and used in schools and universities of Galicia. But most writers (Castelao, Risco, Otero Pedrayo) did not support the traditional Galician forms; some of them based in Spanish orthography even if they recognized the essential linguistic unity, saying that the priority was achieving political autonomy and being read by the population. Other writers wrote with a Portuguese-like orthography (e.g. Guerra da Cal and Carvalho Calero).
