January 2 – Siege of Murcia: King James I of Aragon ("the Conqueror") marches with his army from Orihuela and lays siege at Murcia on the Segura River. Skirmishes break out between the defenders and the Aragonese forces. The Muslim garrison, realizing that they are outnumbered and cut off from reinforcements, asks for terms. James offers to ask King Alfonso X of Castile ("the Wise") to restore the Murcians' legal rights (see 1244) from before the rebellion: self-government under Castilian suzerainty, freedom of worship, and preservation of lands and properties. They agree to this offer but request Alfonso's explicit agreement rather than just James' promise to ask him. James refuses to get Alfonso's agreement before the city surrenders. Finally, the Moors yield Murcia to James on January 31. Seeing his standard on the walls, James enters the city on February 3, accepting its surrender.[1]
February 26 – Battle of Benevento: Guelph forces (some 12,000 men), led by Charles of Anjou, brother of King Louis IX of France, defeat a combined German and Sicilian army under King Manfred of Sicily, during a long-running power struggle in Italy. Manfred takes up a strong position near Benevento. As the French infantry advances, he unleashes his Saracen archers and light cavalry, which scatters the French. But the Saracens leave themselves exposed to the French heavy cavalry, and are overwhelmed. Manfred orders his heavy cavalry (some 1,200 German mercenary knights) into the attack, but they are defeated by the Guelph forces, and take heavy losses. Manfred is killed, and Pope Clement IV invests Charles as ruler of Sicily and Naples. Meanwhile, Michael II, despot of Epirus, invades Albania, and recovers the lands that Manfred has taken from him.[2]
June – The Mudéjar revolt of 1264–1266 ends. The rebels make their formal submission to Alfonso X. They recognize the error that the Moors of Murcia have committed against their overlord Alfonso. Representatives of the aljama, or municipal council, renew their allegiance and humbly beg for pardon, mercy and favour. With this, the Mudéjar uprising in the Kingdom of Murcia is formally ended.[3]
June 23 – Battle of Trapani: The Venetian fleet (24 galleys) led by Admiral Jacopo Dondulo moves to Marsala and attacks the larger Genoese fleet anchored at Trapani, capturing all its ships. Some 1,200 Genoese drown and many are killed. Dondulo is acclaimed a hero on his return to Venice in July and elected as Captain General of the Sea, Venice's highest naval command position.[4]
December 13 – Siege of Kenilworth: English forces under Henry III capture Kenilworth Castle from remaining rebels in the Second Barons' War after a 6-month siege.[7] During the siege Archbishop William Freney tries to negotiate with the garrison but is refused entry.

July 23 – Siege of Safed: Mamluk forces capture the castle of Safed, defended by a garrison of 1,700 men (including some 500 Knights Templar), after a 6-week siege. Sultan Baibars promises safe conduct but when the Christians and Templars are on their way towards Acre, they are seized and beheaded.[8]
October 28 – A Crusader advance guard is ambushed by the Egyptian garrison of Safed, while local Arabs attack the Crusader camp. The 13-year-old Hugh II, ruler of Cyprus, is advised to retire and withdraw with heavy losses. Meanwhile, Baibars campaigns in Galilee and leads a lightning raid to Tripoli.[9]
Asia
Niccolo and Maffeo Polo, father and uncle of Marco Polo, reach the Mongol capital Khanbaliq (modern-day Beijing), setting the stage for Marco's famous expedition 5 years later. Kublai Khan sends the Polos back with a message, requesting that Pope Clement IV dispatch western scholars to teach in the Mongol Empire; however, this request is largely ignored.
America
In the modern-day United States, a period of drought (up until 1299) begins in the Four Corners Region, putting an end to the ancient Puebloans Civilization.
