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.
Abu Al-Hasan 'Ali ibn 'Othman, was a sultan of the Marinid dynasty who reigned in Morocco between 1331 and 1348. In 1333 he captured Gibraltar from the Castilians, although a later attempt to take Tarifa in 1339 ended in fiasco. In North Africa he extended his rule over Tlemcen and Hafsid Ifriqiya, which together covered the north of what is now Algeria and Tunisia. Under him the Marinid realms in the Maghreb briefly covered an area that rivalled that of the preceding Almohad Caliphate. However, he was forced to retreat due to a revolt of the Arab tribes, was shipwrecked, and lost many of his supporters. His son Abu Inan Faris seized power in Fez. Abu Al-Hasan died in exile in the High Atlas mountains.

Beatrice of Castile or Beatriz was an infanta of Castile, daughter of Sancho IV and María de Molina. She was Queen of Portugal from the accession of her husband, Afonso IV, in 1325 until his death on 28 May 1357.
The War of the Castilian Succession was the military conflict contested from 1475 to 1479 for the succession of the Crown of Castile fought between the supporters of Joanna 'la Beltraneja', reputed daughter of the late monarch Henry IV of Castile, and those of Henry's half-sister, Isabella, who was ultimately successful.
Abu al-Hajjaj Yusuf ibn Ismail, known by the regnal name al-Muayyad billah, was the seventh Nasrid ruler of the Emirate of Granada on the Iberian Peninsula. The third son of Ismail I, he was Sultan between 1333 and 1354, after his brother Muhammad IV was assassinated.
Abu Abdullah Muhammad ibn Ismail, known as Muhammad IV, was the ruler of the Emirate of Granada on the Iberian Peninsula from 1325 to 1333. He was the sixth sultan of the Nasrid dynasty, succeeding to the throne at ten years old when his father, Ismail I, was assassinated.
Manuel Pessanha was a 14th century Genoese merchant sailor who served as the first admiral of Portugal at the time of King Denis of Portugal. His brother was the Genoese merchant and administrator, Antonio Pessagno.
The high office of Admiral of the Kingdom of Portugal as the head of the Portuguese navy was created by King Denis of Portugal in 1317 for the Genoese nobleman and naval officer Manuel Pessanha. Although there is evidence that such a title existed before, it seems to have been of only a temporary character, for fleets assembled in times of war. The exception was perhaps Nuno Fernandes Cogominho who seems to have been appointed admiral by King Denis in 1307, and still had that title at his death in 1316, although the conditions are unclear. Nonetheless, Manuel Pessanha was the first person known to hold the title of Almirante-mor as a permanent office for a permanent fleet. All the king's galleys were under his jurisdiction. The conditions of the Pessanha's title stipulated that he must maintain a corps of at least 20 Genoese naval officers at all times and was obliged to serve the king in military service on land as well as sea.
The naval Battle of Saltes Island or Battle of Saltes took place on 17 July 1381, off Saltes Island, between the Crown of Castile and the Kingdom of Portugal during the Third Ferdinand War. The Castilian fleet commanded by Don Fernando Sánchez de Tovar defeated decisively the Portuguese fleet led by João Afonso Telo. The result of the battle was the destruction of the naval offensive capability of Portugal, achieving the Castilian naval supremacy in the Atlantic Ocean.
The Battle of Barcelona was a naval engagement fought in the coastal region of Barcelona, Catalonia, Spain, between the navies of the Crowns of Aragon and Castile, during the War of the Two Peters. A number of months beforehand, a large Castilian fleet had been assembled at Seville by order of the King of Castile, Peter I. Consisting of 128 warships including royal vessels, ships from the King of Castile's vassals, and several others that had been sent by the Castilian-allied monarchs of Portugal and Granada, this large fleet had been entrusted to the Genoese admiral, Egidio Boccanegra, who was seconded by two of his relatives, Ambrogio and Bartolome.
The fourth siege of Gibraltar, fought from June until August 1333, pitted a Christian army under King Alfonso XI of Castile against a large Moorish army led by Muhammed IV of Granada and Abd al-Malik Abd al-Wahid of Fes. It followed on immediately from the third siege of Gibraltar, fought earlier in 1333. The siege began inauspiciously with a disastrous landing by Castilian forces on the west side of Gibraltar, before developing into a stalemate in which neither side had the strength to capture Gibraltar, nor to break out or lift the siege. Both sides faced acute shortages of food – the Gibraltar garrison was cut off from resupply, while the Castilians, deep within enemy territory, could only be resupplied via an unreliable sea route. After two months of inconclusive siege warfare, the Castilians and Moors reached a truce agreement that allowed both sides to make an honourable exit from the siege. Although the Moors managed to keep Gibraltar, the truce cost Muhammed IV his life when he was assassinated by disgruntled nobles the day after signing it.
The siege of Algeciras (1342–1344) was undertaken during the Reconquest of Spain by the Castillian forces of Alfonso XI assisted by the fleets of the Kingdom of Aragon and the Republic of Genoa. The objective was to capture the Muslim city of Al-Jazeera Al-Khadra, called Algeciras by Christians. The city was the capital and the main port of the European territory of the Marinid Empire.
The Battle of Villanueva de Barcarrota was fought in 1336 near the town of Villanueva de Barcarrota in Extremadura between troops of the Kingdom of Portugal led by Pedro Afonso de Sousa, and troops of the Kingdom of Castile led by Enrique Enriquez the Younger, who led the forces of the Bishop of Jaén, assisted by Juan Alonso Pérez de Guzmán y Coronel and Pedro Ponce de León the Elder, who led forces sent by the city of Seville. The Portuguese were defeated. As a result, Afonso IV of Portugal, who was besieging the city of Badajoz, ordered the siege to be lifted and returned with his troops to Portugal.
The Kingdom of Portugal was established from the county of Portugal in the 1130s, ruled by the Portuguese House of Burgundy. During most of the 12th and 13th centuries, its history is chiefly that of the gradual reconquest of territory from the various Muslim principalities (taifas) of the period.
The Battle of Ceuta (1339) was one of the battles of the Battle of the Strait.
The Battle of the Getares of 1340 was a naval encounter between the Marinid fleet, under the command of Mohammed ben Ali al-Azafi, and a Castilian fleet led by Alfonso Jofre de Tenorio. The tough battle ended with the annihilation of the Castilian fleet.
