The Iberian Union united Aragon, Castile, and Portugal.

The Iberian Union marked a significant consolidation of power in Spain. In 1580, the crowns of Aragon, Castile, and Portugal were united under one ruler, Philip II. This union brought together three major kingdoms, expanding Spanish influence across Europe and its colonial territories. With Portugal as a key player in maritime exploration and trade, the Iberian Union gave Spain access to new resources and territories, strengthening its position as a global power. Spain's control over Portugal also sparked tensions with other European nations, particularly England and the Netherlands, who saw the union as a threat to their own trade and colonial aspirations. The Iberian Union had a lasting impact on Spain's history, shaping its politics, economy, and foreign relations for decades to come. #IberianUnion #Spain #Aragon #Castile #Portugal #consolidationofpower
