Mongols, the terrifying warriors of Central Asia, the 'horsemen of the devil', menaced Eurasia in the medieval times. The Mongol Army, led by Genghis Khan and his descendant Khanates, single-handedly brought an end to the Islamic Golden Age, killing every man, woman and child wherever they want. But there was one place they could not invade - the Delhi Sultanate. They attacked India more than 6 times and one man, Alauddin Khilji, repeatedly defeated the Mongols.
