Crown of Castile

The Crown of Castile was a medieval polity in the Iberian Peninsula, formed in 1230 from the union of the crowns and parliaments of the kingdoms of Castile and León under Ferdinand III. It remained a separate entity after the personal union with the Crown of Aragon in 1469, following the marriage of the Catholic Monarchs. Major events in its history include Christopher Columbus's voyage and the discovery of the Americas in 1492, which helped shape it into a global empire in the 16th century. The Crown of Castile continued to exist until the promulgation of the Nueva Planta decrees by Philip V in 1716, which unified it with the Crown of Aragon into the kingdom of Spain.
