Humāyūn on horseback, c.17th century Babur’s son Humayun (birth name Nasir al-Din Muhammad; reigned 1530–40 and 1555–56) lost control of the empire after a rebellion led by the Afghan soldier of fortune Sher Shah of Sur expelled him from India.

Fifteen years later, Humayun took advantage of discord among Sher Shah’s successors to recapture Lahore, Delhi, and Agra. But he wasn’t around long to enjoy his restored empire; he died in a fall down the steps of his library in 1556 that may have been caused by his excessive drinking. He was succeeded by his son Akbar.
