Battle of Río Salado

The Battle of Río Salado also known as the Battle of Tarifa was a battle of the armies of King Afonso IV of Portugal and King Alfonso XI of Castile against those of Sultan Abu al-Hasan 'Ali of the Marinid dynasty and Yusuf I of Granada.After Alfonso XI of Castile's victory in the Teba campaign of 1330, Muhammed IV, Sultan of Granada sent to Abu al-Hasan 'Ali for help in maintaining his survival. The policies of the Kingdom of Fez vis-à-avis the Iberian Peninsula had changed upon the ascension to power of Hasan in 1331. During his rule the Marinids achieved their largest territorial expansion in Africa. Hasan sent a naval fleet and 5,000 troops that landed at Algeciras in early 1333. These set about helping the Granadan King to capture the Castilian outpost of Gibraltar, which he did after less than two months. They then conducted a limited campaign to reunite these territories to the realm of Granada. Back in Magreb, Abu Hasan amassed his biggest army to undertake an invasion of Castile with the intention of undoing the previous century's Christian advances.
