Khan-e-Jahan Bahadur Zafar Jung Kokaltash served as Mughal Sūbehdar (governor) of Lahore from 11 April 1691 – 1693.

Historian Kanhaiya Lal remarks that he was a Vizier and Umrā-ul-Umrā during the reign of the Mughal Emperor Akbar and that he died in 1602.

[1] He was a noble-man, named Khan-e-Jahan Bahadur Zafar Jung Kokaltash, during the reign of Mughal Emperor Aurangzeb.

Another historian, Noor Ahmed Chishti in his "Tehqeeqt-e-Chishti" did not have any written views about Khan-e-Jahan Bahadur, but only wrote about the tomb's structure.

[2][1] The grave of Khan-e-Jahan was demolished in Ranjit Singh's Era when the Sikh Empire collapsed in 1849, and construction of Lahore Cantonment was underway.
