Galician-Portuguese is a branch of Romance languages. They were first spoken in Northwestern Iberia and spread to the south. They are now spoken in all of Portugal and Northwestern Spain. The main two languages are Galician and Portuguese. All Galician-Portuguese languages were once all the same language, but have since split. Portuguese was spread to Brazil during the colonial era and it is also now spoken there.
