The Siege of Esztergom took place in the winter of 1241. Following the hard-fought but decisive Mongol victory at the Battle of Mohi, Batu Khan pillaged the lands of the Kingdom of Hungary, with particular focus on soft targets such as small villages and towns. One exception was Esztergom, the capital and largest, wealthiest city in the Kingdom of Hungary until its destruction. It was the last city to be looted and destroyed by Batu Khan before he sent a reconnaissance party against the Holy Roman Empire and later withdrew of all Mongol forces from central Europe back to Russia. Most of the information on the siege and its aftermath comes from the chronicle of Roger of Torre Maggiore, the Italian (Apulian) archbishop of Split.
