|Native to||Kingdom of Galicia, County of Portugal|
|Era||Attested 870 A.D.; by 1400 had split into Galician, Eonavian, Fala, and Portuguese.|
Spoken area of Galician-Portuguese in the Kingdom of León around the 10th century, before the separation of the Galician and Portuguese languages.
Galician-Portuguese (Galician: galego-portugués or galaico-portugués, Portuguese: galego-português or galaico-português), also known as Old Galician, Old Portuguese, Medieval Portuguese or as Medieval Galician when referring to the history of each modern language, was a West Iberian Romance language spoken in the Middle Ages, in the northwest area of the Iberian Peninsula. Alternatively, it can be considered a historical period of the Galician and Portuguese languages.
Galician-Portuguese was first spoken in the area bounded in the north and west by the Atlantic Ocean and by the Douro River in the south, comprising Galicia and northern Portugal, but it was later extended south of the Douro by the Reconquista.
It is the common ancestor of modern Portuguese, Galician, Eonavian, and Fala varieties, all of which maintain a very high level of mutual intelligibility. The term "Galician-Portuguese" also designates the subdivision of the modern West Iberian group of Romance languages.
