Mubariz al-Din Muhammad (Persian: مبارز الدین محمد; 1301–1363), was the founder of the Muzaffarid dynasty, ruling from 1314 to 1358.
In the wake of the loss of Ilkhanate authority in central Iran following the death of Abu Sa'id, Mubariz al-Din continued to carry out his expansionary policy, and declared independence from the Ilkhanids.
Abu Esshaq, however, managed to escape from Shiraz and fled to Isfahan, but Mubariz al-Din pursued him, took the city and executed the Injuid ruler.
Mubariz al-Din's strength was such that when the Khan of the Golden Horde, Jani Beg, sent an offer to become his vassal, he was able to decline.
He defeated the khan's governor Akhichuq and occupied Tabriz, but realized that he could not hold his position against the Jalayirid troops marching from Baghdad and soon retreated.
