Humayun
LeaderPerson
Mughal emperor in the Bengal campaign era
“Humayun's Bengal campaign marked the first major Mughal intervention in Bengal's sixteenth-century power transition.”
He led the Mughal eastern campaign that entered Bengal and occupied Gaur before the reversals at Chausa and Kannauj.
His conflict with Sher Shah Suri framed the first major Mughal-Afghan struggle over Bengal-adjacent power.
His setbacks delayed stable Mughal control and opened a period of Afghan resurgence in north India and Bengal politics.

Afghan ruler who defeated Humayun at Chausa
“Afghan ruler whose capture of Gaur and victory at Chausa displaced the Mughals from Bengal's eastern power struggle.”
Sher Shah Suri, born Farid Khan, captured Gaur in 1538 and defeated Humayun at Chausa on 26 June 1539. These victories made him the dominant Afghan power in the eastern subcontinent and helped establish the Sur imperial order.
His rise grew from Afghan power networks in Bihar and Bengal during the weakening of the Bengal Sultanate and the first Mughal intervention in the region. After Humayun temporarily occupied Gaur, Sher Shah recovered Bengal and used the victory at Chausa to push the Mughals out of the east before defeating Humayun again at Kannauj in 1540.
Sher Shah interrupted early Mughal consolidation and reorganized the political map across Bengal, Bihar, and North India. His short reign is also associated with revenue and bureaucratic reforms, but the Sur state did not produce a permanently stable succession; Mughal power returned under Humayun and Akbar, while Bengal retained its own regional political dynamics.

Hussain Shahi sultan, diplomat, and frontier ruler
“Nusrat Shah preserved Bengal's independence through expansion and diplomacy as Afghan power gave way to the Mughals in northern India.”
Nusrat Shah, eldest son and successor of Alauddin Husain Shah, ruled Bengal from 1519 to 1532. Having participated in administration before his accession, he extended Bengal's influence into Tirhut and established a headquarters at Hajipur. His reign maintained the territorial and commercial strength of the Hussain Shahi state while facing pressure from Tripura, Orissa, Afghan nobles, and the new Mughal power in north India.
After Babur defeated the Lodis at Panipat in 1526, Nusrat gave shelter to defeated Afghan leaders including Mahmud Lodi but avoided joining their anti-Mughal confederacy. The resulting confrontation at Ghogra brought Mughal forces to Bengal's frontier; after a Bengal defeat, Nusrat negotiated peace and accepted a neutral posture. His diplomacy prevented Babur from pressing immediately into Bengal, though it required balancing refuge, frontier defence, and imperial threat.
Nusrat's reign preserved Bengal's independence during a dangerous transition, but he died before an intended alliance with Gujarat's Bahadur Shah could develop. Portuguese missions reached his court in the 1520s and secured trading privileges, while his period also saw important architectural activity, including the Shailkupa Mosque and monuments associated with Gaur. Coins and inscriptions from his reign document a prosperous, administratively active sultanate.
