Medieval Galician Portuguese
Medieval Galician-Portuguese, also known as Old Galician-Portuguese, Galaic-Portuguese, or simply Medieval Galician or Medieval Portuguese, was a Romance language spoken in the Middle Ages in the northwest region of the Iberian Peninsula. This linguistic region encompassed parts of what are today Galicia in Spain and Portugal. This language is the common ancestor of modern Galician and Portuguese.
The earliest known documentation containing Galician-Portuguese words dates back to 870 AD with the Doação à Igreja de Sozello, although predominantly composed in Medieval Latin. It was a pivotal cultural and literary language during the Christian Reconquista of the Crown of Castile, which included the Kingdoms of Castile, León, and Galicia, analogous to the role of Catalan in the Crown of Aragon or Occitan in France and Italy.
Galician-Portuguese is renowned for its rich tradition of lyric poetry, known as troubadour poetry. This tradition includes several poetic forms such as the cantiga de amigo, cantiga de amor, and cantigas de escárnio e maldizer. These works were often composed by troubadours and jograis, showcasing themes of love, friendship, satire, and social commentary. The Cantigas de Santa Maria, a collection of 420 poems with musical notation compiled during the reign of Alfonso X of Castile, exemplifies the spiritual and artistic expression of the time.
The language exhibited features characteristic of Western Iberian romance languages and was marked by the use of nasal vowels, a trait which continues to distinguish Portuguese from other Romance languages. The syntax, morphology, and vocabulary of medieval Galician-Portuguese laid the groundwork for its modern descendants.
While initially a unified language, Galician and Portuguese began to diverge over time due to political, social, and cultural influences, with Portuguese evolving into the language of the Kingdom of Portugal, and Galician remaining under the influence of the Spanish kingdoms.
