Harsha Vadhana becomes king of Thaneshwar (near Delhi) at 16 and soon after goes on a 6 year long relentless campaign to bring all the small kindoms under his rule. Though, at the end he emerges to be the most powerful king of the times, he isnt very successful in his campaigns. He manages to create an kingdom that streached from Gujarat to Bengal, but it is more a state bound togeather by loose treaties and alliances. The state is not as well managed as it was during the previous two great empires.. another Chinese traveller Hsuang Tsang visiting the country this time, is robbed twice in his journey. The entire empire was built on the charisma of the leader and when he dies in 647, the emipre died with him.
