The Battle of the Strait (Spanish: Batalla del Estrecho) was a military conflict contesting the ports in the Straits of Gibraltar taking place in the late thirteenth century and the first half of the fourteenth. The conflict involves principally the Spanish Muslim Emirate of Granada, the Spanish Christian Crown of Castile and the North African Muslim Marinid state. The ports' strategic value came from their position linking Spain and North Africa, thus connecting Muslims in Spain with the rest of the Islamic world.[1][2] The campaign had mixed results. Castile gained Tarifa permanently, and managed to take Gibraltar and Algeciras but both would revert to Muslim rule. Castile also failed to gain any port in the African side of the strait.[3]
