For centuries, the Iberian Peninsula had been divided into multiple nations. The point of divergence occurs in 1470, when Queen Isabella I of Castile and King Ferdinand II of Aragon combine their crowns to form the Kingdom of Spain. To further unite the peninsula, the powerful Spanish Army swiftly invade the Emirate of Granada in 1472, and the Kingdom of Navarre in 1476. Along with a strong ally in Portugal, Spain decided to head to North Africa, giving the nations a head start on their voyages to the New World.
