II,III and IV

The founder of the empire, Zahiruddin Babur, was driven from his Central Asian homeland, Farghana, by the warring Uzbeks. He first established himself at Kabul and then in 1526 pushed further into the Indian subcontinent in search of territories and resources to satisfy the needs of the members of his clan. His successor, Nasiruddin Humayun (1530-40, 1555-56) expanded the frontiers of the empire, but lost it to the Afghan leader Sher Shah Sur, who drove him into exile. Humayun took refuge in the court of the Safavid ruler of Iran. In 1555 Humayun defeated the Surs, but died a year later.
