The Kingdom of Galicia was a political entity located in southwestern Europe, which at its territorial zenith occupied the entire northwest of the Iberian Peninsula. It was founded by the Suebic king Hermeric in 409, with its capital established in Braga. It was the first kingdom that officially adopted Catholicism. In 449, it minted its own currency. In 585, it became a part of the Visigothic Kingdom. In the 8th century, Galicia became a part of the newly founded Christian Kingdom of Asturias, which later became the Kingdom of León, while occasionally achieving independence under the authority of its own kings. Compostela became the capital of Galicia in the 11th century, while the independence of Portugal (1128) determined its southern boundary. The accession of Castilian King Ferdinand III to the Leonese kingdom in 1230 brought Galicia under the control of the Crown of Castile.

Galician, also known as Galego, is a Western Ibero-Romance language. Around 2.4 million people have at least some degree of competence in the language, mainly in Galicia, an autonomous community located in northwestern Spain, where it has official status along with Spanish. The language is also spoken in some border zones of the neighbouring Spanish regions of Asturias and Castile and León, as well as by Galician migrant communities in the rest of Spain, in Latin America including Puerto Rico, the United States, Switzerland and elsewhere in Europe.
