The Battle of Los Alporchones is fought in the context of the Spanish Reconquista between the Emirate of Granada and the combined forces of the Kingdom of Castile and Murcia resulting in a Christian

The combined forces of the Kingdom of Castile and the city of Murcia defeated a raiding army from the Emirate of Granada at the Battle of Los Alporchones on March 17, 1452, securing the southeastern frontier of Christian Spain and demonstrating that Granada's military capabilities were declining even as the emirate clung to its last century of existence. The battle arose from one of the periodic Granadan raids into Murcian territory that characterized the long twilight of the Spanish Reconquista. The Emirate of Granada, the last Muslim state on the Iberian Peninsula, survived by playing Castile and Aragon against each other through diplomacy and by launching raids that captured slaves and livestock from Christian border settlements. Alonso Fajardo el Bravo, the Adelantado (military governor) of Murcia, led the Christian response with a force of approximately 700 Castilian and Murcian troops against a larger Granadan army. The battle took place near Lorca, in the arid terrain of southeastern Spain where the border between Christian and Muslim territory had fluctuated for centuries. Despite being significantly outnumbered, Fajardo's forces achieved a decisive victory. The Christian cavalry proved superior in the open terrain, and the Granadan force suffered heavy casualties before withdrawing toward the mountain passes leading back to Granada. The victory secured the Murcian frontier and reduced the frequency of Granadan raids into the region for years afterward. Los Alporchones was one of dozens of border battles fought during the fifteenth century as the Reconquista ground toward its conclusion. The Emirate of Granada, ruled by the Nasrid dynasty, would survive for another forty years before Ferdinand and Isabella's forces finally conquered the city on January 2, 1492. The battle demonstrated that Granada's survival depended not on military strength but on Castilian internal divisions that prevented a sustained campaign against the last Muslim kingdom in Western Europe.
