Sur Empire
Sher Shah died soon after in 1545 at Kalinjar. He was succeeded by his younger son, Islam Shah Suri, who was a capable ruler. However, upon his death in 1553, the Sur Empire was caught up in a succession battle and was plagued by rebellion and the secession of provinces. Humayun made use of this discord to recapture what was lost and on 23 July 1555, the Mughals defeated Sikandar Shah Suri and finally regained control over Delhi and Agra.
