Sher Shah Suri

Humayun (1508-1556), the second Mughal emperor, inherited Babur's unconsolidated conquests in 1530, lost them to Sher Shah Suri by 1540, spent some fifteen years in exile including refuge with the Safavids, and recovered Delhi in 1555 months before his death.

Sher Shah Suri (c. 1486-1545) drove the Mughal emperor Humayun out of India and ruled the north from 1540 to 1545. In five years he built a revenue system based on land measurement, minted the silver rupiya behind the rupee, and restored the Grand Trunk Road.
