Haji Munir Khan was the only son of Azim Khan, the landlord of the Khanpur estate in Bulandshahr district. Munir Khan was the main commander of the revolutionaries of the Bulandshahr district during the Great Uprising of 1857.
In the famous second battle of Gulaothi which was fought on 29 July 1857 the British forces wanted to take control over the whole of the Bulandshahr district. To stop their advance, Nawab Walidad Khan of Malagarh deputed his main commanders Haji Munir Khan and Ismail Khan to Gulaothi. Both of them established a picket on the canal just before Gulaothi to stop the colonial force from entering the Bulandshahr district. Both Haji Munir Khan and Ismail Khan got severe sword cuts on their faces.
Later on, Haji Munir Khan crossed the Ganga with Walidad Khan and joined Khan Bahadur Khan’s forces and fought at Kachhla ghat. He continued fighting until his last breath.
The family’s erstwhile Khanpur estate in the Bulandshahr district was subsequently confiscated by the British after the 1857 uprising was crushed by the colonial forces.
