Sher Shah Suri (reigned 1540–1545) was an Afghan ruler who briefly displaced the Mughal emperor Humayun and founded the Sur Empire in northern India. Rising from relatively modest origins, he proved to be a highly capable leader and administrator, defeating Humayun and establishing efficient governance across his realm. Sher Shah introduced major reforms, including a standardized currency system (notably the silver rupiya), improved revenue administration, and an extensive road network highlighted by the Grand Trunk Road, which facilitated trade and communication. Though his reign was short, his administrative innovations had a lasting influence and were later adopted and expanded by the Mughal Empire.
