 * August 23 – Battle of Tagliacozzo: The army of Charles of Anjou defeats the Ghibellines supporters of Conradin of Hohenstaufen, marking the fall of the Hohenstaufen Family from the Imperial and Sicilian thrones, and leading to the new chapter of Angevin domination in Southern Italy.
 * October 29 – Conradin, the last legitimate male heir of the Hohenstaufen Dynasty of Kings of Germany and Holy Roman Emperors, is executed, along with his companion Frederick I, Margrave of Baden, by Charles I of Sicily, a political rival and ally to the hostile Roman Catholic Church.
 * King Stephen V of Hungary launches a war against Bulgaria.
 * The County of Wernigerode becomes a vassal state of the Margrave of Brandenburg.
 * New election procedures for the election of the doge are established in Venice, in order to reduce the influence of powerful individual families and possibly to prevent the popular Lorenzo Tiepolo from becoming elected.
