Isabella I of Castile and Ferdinand II of Aragon, known as the Catholic Monarchs, ruled over the Personal Union of Aragon and Castile from 1479 to 1516. During their reign, they successfully completed the Reconquista, the centuries-long campaign to expel the Moors from the Iberian Peninsula, with the capture of Granada in 1492. They also sponsored Christopher Columbus' voyage to the Americas in the same year, leading to the beginning of Spanish colonization. The most significant war during their tenure was the War of Granada (1482-1492), which culminated in the fall of the last Muslim stronghold in Spain.
