Sher Shah Suri (1540−1545) established a powerful state. He started his career as the manager of a small territory for his uncle in Bihar and eventually challenged and defeated the Mughal Emperor Humayun, Sher Shah captured Delhi and established his own dynasty known as the Suri dynasty. Although the Suri dynasty ruled for only a short period i.e. 15 years, it introduced an administration that borrowed elements from Alauddin Khilji and made them more efficient. The great emperor Akbar followed the techniques of Sher Shah's administration while consolidating the Mughal Empire.
