Mongol invasions and conquests
Series of military campaigns (1206–1308) / From Wikipedia, the free encyclopedia
The Mongol invasions and conquests took place during the 13th and 14th centuries, creating history's largest contiguous empire, the Mongol Empire (1206–1368), which by 1260 covered large parts of Eurasia. Historians regard the Mongol devastation as one of the deadliest episodes in history.[4][5]
