Mubāriz Khān (Bengali: মুবারিজ খান, Persian: مبارز خان) was a Mughal Empire commander during the reign of emperor Jahangir.
After Mubariz's return to Jahangirnagar from Fathabad, he was given charge of Fort Jatrapur, which was previously run by the rebel Musa Khan.
After Islam Khan I was informed of this incident, he changed his plan as soon as he reached Toke by ordering Mubariz to go and attack Anwar's forces.
Anwar, who had previously called for ceasefire, heard of Usman's departure and surrendered to Mubariz and Satrajit with no hope left.
[2] Pratapaditya of Jessore later surrendered to the Mughals, sending his son Sangramaditya to Islam Khan I and donating 80 war boats.
The Subahdar then sent an army led by Ghiyas Khan to punish Pratapaditya for his past actions and to reincorporate Jessore to Mughal territory.
Due to this case, Qasim Khan ordered his bakhshi (paymaster), Khwaja Tahir Muhammad, to reinstate their titles and jagirs and to inform the imperial Court of this reformation.
[citation needed] Mubariz, wishing that when a new Subahdar arrives that he could show him his record of achievements and get on his good side, decided to lead an expedition to Pratapgarh, also under the domain of the Raja of Kachar.
They have said that during the reign of Timur in the late 12th century, the emperor had reached this extreme point and left a group of Mongols to protect the land before returning to his capital in Baghdad.
Members of this tribe were white-skinned, spoke a Sino-Tibetan language, ate all sorts of animals and vegetables, and wore large turbans and big brass earrings (tunkal).
Mubariz returned to Sylhet thana and appointed Mirak Bahadur Jalair to govern this new tribal area and to keep a lookout for trouble.
[5] Mubariz Khan later invaded the Kachari Kingdom as commander of the expedition, managing to defeat the Raja and establishing a fort and thana in Asurainagar.
However, after learning that Mirak had fled from his appointed territory, which had recently been conquered by Mubariz with a lot of difficulty, Qasim was not impressed at what he viewed as "cowardice".
