In 1526, Babur, a Timurid descendant of Timur and Genghis Khan from Fergana Valley (modern day Uzbekistan), swept across the Khyber Pass and established the Mughal Empire, which at its zenith covered much of South Asia. However, his son Humayun was defeated by the Afghan warrior Sher Shah Suri in the year 1540, and Humayun was forced to retreat to Kabul. After Sher Shah's death, his son Islam Shah Suri and his Hindu general Hemu Vikramaditya established secular rule in North India from Delhi until 1556, when Akbar the Great defeated Hemu in the Second Battle of Panipat on 6 November 1556 after winning Battle of Delhi.
