AGAL made its name in the public domain in 1983, when its Comissom Lingüística (Linguistic Commission) passed a new set of rules and norms for the Galician language with the title Estudo crítico das «Normas Ortográficas e Morfolóxicas do Idioma Galego» ("Critical study of 'Galician Language Spelling and Morphological Rules'"). This study radically diverged from the norms of the Real Academia Galega (Royal Galician Academy) published in 1982. The AGAL norm was somewhat based in the 1979 official draft for the Galician language prepared under the direction of professor Carvalho Calero. With the dismissal of Carvalho Calero due to political reasons and the subsequent approval of a different set of spelling norms the debate between isolationists and reintegrationists (led by AGAL) was ignited.^{[citation needed]}

AGAL considers that "Galician" is the denomination that Galician-Portuguese language should receive in Galicia, and assumes that the international name is Portuguese. Following the reintegracionist ideas, AGAL defends that Galician and Portuguese are two varieties of the same language, in other words, two versions of the same diasystem. This view is based on the facts that Galician and Portuguese share an almost identical grammar, syntax, morphology, vocabulary and that natural mutual intelligibility is over ninety per cent.^{[citation needed]}

Members of AGAL have been regularly present at the meetings of the CPLP (Community of Portuguese-Speaking Countries). In 2008, AGAL delegates were invited as speakers to the Portuguese Parliament when discussing the new spelling norms for Portuguese language.^[1]

Although AGAL was first founded under the auspices and guidance of Carvalho Calero, its first president was writer Xavier Alcalá (1981–82), followed by Maria do Carmo Henríquez Salido (1982–2001). The president from 2001 to 2007 was Bernardo Penabade. Alexandre Banhos held the presidency from June 2007 to May 2009, when he was replaced by president Valentim Rodrigues Fagim[1]. From October 2012 to October 2015, Miguel Rodrigues Penas[2] was the head of the association, and after him came the current president, Eduardo Maragoto[3].

AGAL has published a large number of titles on linguistics, Galician language and culture [4].

Since 1995 it has edited the quarterly Agália. Agália is in fact considered a reference journal in the domain of Galician and Portuguese culture and linguistics, although it also deals with a wide array of topics. Likewise, AGAL fosters the Universália, Criaçom, Música and Clássicos book collections. Through its web portal AGAL also provides for electronic publishing through GZ e-editora. The web portal also hosts an exhaustive dictionary, the e-Estraviz [5], among other free resources.

The orthographic reintegration campaign held by the AGAL is not supported by any of the Galician political parties currently represented in the Galician Parliament, although some members of parliament support it individually or express a sympathy towards its theoretical foundations.

AGAL has been accused by some of being closely linked to extreme-left minority groups.^[2] Indeed, such groups often use the AGAL orthography and some AGAL members may militate in them. However AGAL per se and as an institution has successfully managed to separate itself from any particular political camp and remain neutral, focusing only on the scientific aspects of linguistics.^{[citation needed]}
