==== Europe ====

* Summer &ndash; Emperor [[Frederick II, Holy Roman Emperor|Frederick II]] assembles an expeditionary force (some 15,000 men) to crush the rebellious [[Lombard League]]. He crosses the [[Alps]] to [[Verona]] – where he is joined by Lord [[Ezzelino III da Romano]], including troops from [[Brescia]], [[Vicenza]], [[Padua]] and [[Treviso]]. Frederick relies on his allies for support and in doing so, he provokes the opposition of earlier supporters, such as the [[House of Este]], which now sides with the Lombards.
* [[August 15]] &ndash; [[Battle of the Puig]]: Aragonese forces under [[Bernat Guillem de Montpeller]] defeat the Muslim army (some 12,000 men) of the [[Taifa of Valencia]] at [[El Puig]]. The Almohad forces are routed, and many of the soldiers are slain in the action. [[Zayyan ibn Mardanish]], Almohad ruler and governor of [[Valencia]], is forced to go into exile to [[Tunisia]], while offering the surrender of all castles from the [[Turia (river)|Turia River]] to [[Tortosa]] and [[Teruel]].
* [[November 27]] &ndash; [[Battle of Cortenuova]]: Frederick II defeats the forces of the Lombard League; about 5,000 Lombards are captured.

The townspeople repel the first Mongol attacks but after 5 days the city walls are breached by Chinese catapults.
