Galicia–North Portugal Euroregion

This inter-regional co-operative effort has been shaped and justified both by the economic potential of cooperation between nearby northern Portuguese and Galician industrial core cities[citation needed], as well as by historical, cultural and ethnolinguistic ties.

[citation needed] However, by the 9th century the political unity of both territories already started to fade when the title of count was given to the nobleman Vímara Peres by Alfonso III of Asturias after his successful campaign in the reconquest of Portus Cale (Porto).

This shared vernacular of became one of the most important lyrical and literary languages of Europe and was taken in great regard by the neighboring Castilian royal court, with works such as Cantigas de Santa Maria, the Martín Codax's Pergaminho Vindel and the Cancioneiro da Ajuda being written during this period.

Moving into the Late Middle Ages the cultural and political division between the two territories increased, a process which reached its climax with the rise of the modern Spanish and Portuguese nation states, (with regional identity and language suppressed under Francoist Spain in particular).

In the particular case of Galicia and the north of Portugal, their prevalent social ties and cultural resemblance, along with demand for a mutual and strengthened infrastructure and city-based economies, creates a demand for better transport services and connections between neighboring cities like Vigo or Porto, as well as other agreements of a diverse nature, such as cultural and educational exchanges, bilateral political strategies, and ethnogastronomic accords.
