Джанибек
With the destruction of Injuid authority, the Muzaffarids were the strongest power in central Iran, and Shiraz was made their capital. 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. In fact, he pushed on into Azerbaijan, which Jani Beg had conquered in 1357. 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. The Jalayirids would therefore maintain a hold on Tabriz, despite further attempts by the Muzaffarids to take it.
