Why did Genghis khan came to the sub-continent?

Answer 1

A Muslim leader,the shah of khwarezm ruled an area of west Turkestan.the shah knew little and cared less about the mongols.in 1219 Genghis Khan sent some merchants and ambassadors but the shah allowed their caravan to be looted.some of them were killed.

Genghis khan was not pleased.he got together his army of 100,000 men.he marched to Turkestan and attacked the shah,who fled into the subcontinent. Genghis khan caught up with him at Attock in 1221. there the shah was defeated and an old story says that he jumped into the river with his armour on and swam across to safety. the mongols then attacked the western Punjab and the Peshawar and Multan provinces and raided and ruined Lahore. Genghis khan soon left the subcontinent but left behind mongol troops in the Punjab.
