Europe

 * June 11 – Battle of Campaldino: Pro-papal Guelph forces of Florence and their allies, Lucca, Pistoia, Prato and Siena under Viscount Aimery IV defeat the Ghibelline army (some 10,000 men) in Tuscany. Florence becomes the dominant power in Central Italy; powerful merchant guilds take on a more political role in the communal government against their rivals of Genoa, Pisa and Venice.
 * July 7 – Battle of Copenhagen: A Norwegian expeditionary force under King Eric II, supported by Danish outlaws, sets sail to Copenhagen and attacks the city. But they are repelled and forced to withdraw to Zealand.

Britain

 * Summer – King Edward I (Longshanks) proposes a marriage between his infant son, Edward of Caernarfon, and the 6-year-old Margaret (Maid of Norway).
 * Construction of Conwy Castle in Wales, ordered by Edward I (Longshanks), is completed.

Levant

 * February 9 – Sultan Qalawun (the Victorious) marches the Mamluk army out of Cairo, leaving his son Al-Ashraf Khalil commanding Cairo's Citadel, supported by Viceroy Baydara al-Mansuri. The army moves via Salihiya, across Sinai and through Jordan to Damascus. He orders the regional governors of Syria to mobilize in Damascus, where many infantry volunteers have assembled.
 * March – The 19-year-old King Henry II sends his younger brother Almalric, with a company of knights and 4 galleys to Tripoli (modern Lebanon). Meanwhile, many non-combatant citizens flee to Cyprus. The Mamluk army arrives before Tripoli and begins the attack with siege engines, while building buches (wooden defensive structures) outside the city on March 25.
 * April 26 – Siege of Tripoli: Mamluk forces under Qalawun (the Victorious) capture Tripoli after a month-long siege, thus extinguishing the County of Tripoli. Qalawun orders the city to be razed to the ground, a widespread massacre kills every man found by the Mamluks, while the women and children are taken as slaves.
 * July–August – Admiral Benedetto Zaccaria, having escaped from Tripoli, starts a naval campaign against Mamluk shipping and raids Tinnis in Egypt. In response, Qalawun closes Alexandria to Genoese merchants.
