- King John II of Portugal oversaw the construction of São Jorge da Mina fortress on the Gold Coast, establishing a permanent Portuguese presence for the gold trade in West Africa.
- Spanish forces captured the town of Alhama de Granada in February, securing a strategic position deep within Nasrid territory and boosting Castilian morale.
- Cem Sultan, defeated in his bid for the Ottoman throne, sought refuge with the Knights Hospitaller on Rhodes, becoming a valuable political hostage for Christian powers.
