As the third largest city in the County of Flanders (after Ghent and Bruges) Ypres played an important role in the history of the textile industry. Textiles from Ypres could be found in the markets of Novgorod in Kievan Rus' in the early 12th century. In 1241, a major fire ruined much of the old city. The powerful city was involved in important treaties and battles, including the Battle of the Golden Spurs, the Battle at Mons-en-Pévèle, the Peace of Melun, and the Battle of Cassel.
