Reconquista: After a four-month siege, the Catholic Monarchs of Spain conquered the city of Málaga from the Emirate of Granada.

The Reconquista or the fall of al-Andalus was a series of military and cultural campaigns that European Christian kingdoms waged against Muslim-ruled al-Andalus, culminating in the reign of the Catholic Monarchs of Spain.

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.

The Catholic Monarchs were Queen Isabella I of Castile and King Ferdinand II of Aragon, whose marriage and joint rule marked the de facto unification of Spain. They were both from the House of Trastámara and were second cousins, as they were both descended from John I of Castile. To remove the obstacle that this consanguinity would otherwise have posed to their marriage under canon law, they were given a papal dispensation by Sixtus IV. They married on October 19, 1469, in the city of Valladolid; Isabella was 18 years old and Ferdinand a year younger. Most scholars generally accept that the unification of Spain can essentially be traced back to the marriage of Ferdinand and Isabella. Their reign was called by W.H. Prescott "the most glorious epoch in the annals of Spain."

Málaga is a municipality of Spain, capital of the Province of Málaga, in the autonomous community of Andalusia. With a population of 591,637 in 2024, it is the second-most populous city in Andalusia and the sixth most populous in the country. It lies in Southern Iberia on the Costa del Sol of the Mediterranean, primarily in the left bank of the Guadalhorce. The urban core originally developed in the space between the Gibralfaro Hill and the Guadalmedina.
