favourable to Portugal. They gave Portugal commercial control and ample religious authority over all of Guinea, and in areas "further beyond". The Holy See did not arbitrate the question of the Canaries, whose conquest had been left relatively suspended. The King of Portugal adopted a freer commercial policy that allowed foreign subjects to trade on the African coasts, in exchange for taxes. In August 1475, after the start of the war, Isabella claimed that parts of Africa and Guinea belonged to Castile by right and incited Castilian merchants to sail to them. That initiated a naval war in the Atlantic.

War at sea

One of the objectives of Isabella and Ferdinand was to challenge Portugal's monopoly on the rich Atlantic territories of Guinea. The gold and slaves constituted an important source of income which could be used to finance the war, and therefore expeditions to Guinea became a priority for both belligerent sides. Portuguese ships had transversed the Andalusian coast, apprehending fishing and merchant ships, since the start of the war. To stop this, Isabella and Ferdinand sent four

Coullon attempted to capture the merchants through a ploy, but failed, and was forced to engage in combat. The Franco-Portuguese side emerged victorious. Due to the use of incendiary weapons by the French, fire razed two Genoese ships, the Flemish vessel, two Portuguese galleys, and two of Coullon's ships. According to Palencia, some 2,500 French and Portuguese died.


Consolidation of Isabella and Ferdinand (September 1476 – January 1479)

After their strategic victory at the battle of Toro, the repulsion of the French attack, and the truce with Afonso V, Isabella and Ferdinand were in a powerful position to obtain the throne of Castile. Nobles of the Joanna alliance were forced to accept the circumstances and gradually pledged their allegiance to Isabella and Ferdinand. The war was reduced to skirmishes along the Portuguese border and the continuation of the naval war for control of the Atlantic commerce.

Return of Afonso V

After his diplomatic failure in France, Afonso V decided to return to Portugal. When he arrived in Portugal in October 1477, he found that his son John had proclaimed himself king. However, John happily received the return of his father and returned the Crown to him immediately.
