Granada War: Forces of Aragon and Castile began a siege of Málaga, a Muslim city in the south of the Iberian Peninsula.

The Granada War was a series of military campaigns between 1482 and 1492 during the reign of the Catholic Monarchs, Isabella I of Castile and Ferdinand II of Aragon, against the Nasrid dynasty's Emirate of Granada. It ended with the defeat of Granada and its annexation by Castile, ending the last remnant of Islamic rule on the Iberian peninsula.

The Crown of Aragon was a composite monarchy ruled by one king, originated by the dynastic union of the Kingdom of Aragon and the County of Barcelona and ended as a consequence of the War of the Spanish Succession. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy controlling a large portion of present-day eastern Iberian Peninsula, parts of what is now southern France, and a Mediterranean empire which included the Balearic Islands, Sicily, Corsica, Sardinia, Malta, Southern Italy, and parts of Greece.

The Crown of Castile was a medieval polity in the Iberian Peninsula that formed in 1230 as a result of the third and definitive union of the crowns and, some decades later, the parliaments of the kingdoms of Castile and León upon the accession of the then Castilian king, Ferdinand III, to the vacant Leonese throne. It continued to exist as a separate entity after the personal union in 1469 of the crowns of Castile and Aragon with the marriage of the Catholic Monarchs up to the promulgation of the Nueva Planta decrees by Philip V in 1716.

The 1487 siege of Málaga was an action during the Reconquest of Spain in which the Catholic Monarchs of Spain conquered the city of Mālaqa from the Emirate of Granada. The siege lasted about four months. It was the first conflict in which ambulances, or dedicated vehicles for the purpose of carrying injured persons, were used. Geopolitically, the loss of the emirate's second largest city—after Granada itself—and its most important port was a major loss for Granada. Most of the surviving population of the city were enslaved or put to death by the conquerors.
