Iberian Federalism, Pan-Iberism or simply Iberism (Spanish, Basque, Portuguese and Galician:Iberismo, Catalan:Iberisme) is a pan-nationalist ideology developed mainly during the beginning of the 20th century, supporting the federation into a single state of the two main countries on the Iberian Peninsula: Portugal and Spain.
