The Mongol Empire launched several invasions into the Indian subcontinent from 1221 to 1327, with many of the later raids made by the unruly Qaraunas of Mongol origin. The Mongols occupied parts of modern Pakistan and other parts of Punjab for decades. As the Mongols progressed into the Indian hinterland and reached the outskirts of Delhi, the Delhi Sultanate led a campaign against them in which the Mongol army inflicted huge losses on the rival army, but were beaten back nonetheless.
