Mention the difficulties faced by Humayun after coming to the throne.
Humayun faced innumerable difficulties to retain the Mughal empire in India. He had to face opposition from his brothers, relatives, Afghans and Rajputs.
He multiplied his problems with own follies. He was addicted to opium. He lacked the military ability. Humayun was defeated by an Afghan, Sher Shah Suri at Chausa and Kanauj and was forced to leave India and take refuge in Iran in 1540.
