The two main regions that fought to control Spain were Castile and Aragon. Their rivalry culminated in the unification of the Kingdom of Spain under the Catholic Monarchs, Ferdinand II of Aragon and Isabella I of Castile, in the late 15th century. This unification was marked by the completion of the Reconquista in 1492 and the establishment of a centralized Spanish monarchy. The struggles between these regions were crucial in shaping the political landscape of Spain.
