By place

Europe

• Spring – Sultan Abu Yusuf Yaqub ibn Abd al-Haqq and Muhammad II, ruler of Granada, agree to a truce with King Alfonso X (the Wise) for two years. Before Abu Yusuf leaves, Muhammad's secretary addresses a poem to Abu Yusuf, expressing fear of Castile's power and appealing for Marinid's continued support. Later, Abu Yusuf lands at Alcázar Seguir on January 19. This ending the first Marinid invasion in Al-Andalus (modern Spain).
• June – King Rudolf I declares war on his rival Ottokar II. After 6 months of campaigning, Ottokar surrenders all his lands (including Austria and Styria) except Bohemia and Moravia. Rudolf makes Vienna his capital, marking the beginning of the Habsburg Dynasty, which will last until 1918.

England

• Spring – King Edward I (Longshanks) orders the people of Bayonne in Gascony (as part of the only English possessions in France) to provide Castile with warships "to resist the Saracens by sea", but he excuses himself from personal participation against the Marinid invasion in Spain because of his wars in Wales and his plan to lead a Crusade to the Holy Land.

Africa

• Battle of Dongola: Mamluk forces led by Sultan Baibars gain a decisive victory against the Kingdom of Makuria. They capture the Makurian capital of Dongola and force King David of Makuria to flee upstream on the Nile.

Later, Baibars conquers Al-Maris (Lower Nubia), previously a part of Makuria, and annexes it into Egypt.
