The Naval Battle of Algeciras occurred amidst the intense military rivalry characterizing the Iberian Peninsula during the Reconquista. Following the fall of Toledo to Castilian forces in 1085 and subsequent gains by both Kingdoms of Castile and Aragon against Muslim-held territories, the Emirate of Granada emerged as a significant Muslim state in the region. By the late 13th century, the Maranid Dynasty, based in Morocco, sought to exert influence over southern Spain and defend Islam against the advancing Christian kingdoms.

On the waters near Algeciras, the Maranid fleet clashed with the forces of the Kingdom of Castile. The battle was strategically critical, as control of the Strait of Gibraltar was vital for both trade and military logistics. The Maranid forces, comprising experienced sailors and equipped with galleys, engaged the Castilian navy in what would become a heralded naval clash. Thanks to their superior tactics and naval technology, the Maranids were able to not only secure a victory but also project power in the Mediterranean region.

The outcome of the battle reflected the shifting dynamics in Iberian warfare and the capability of Muslim powers to effectively challenge the encroaching Christian states. As a result, the victory at Algeciras bolstered the confidence of the Maranid Dynasty and solidified their alliances with other Muslim states in North Africa while instilling caution among the Castilian leadership. This moment further exemplified the volatile nature of the Reconquista, as Muslim and Christian kingdoms continued to vie for supremacy.
