The Muzaffarids have been described as an Arab, Iranian, and Persian dynasty. Their ancestors arrived from Arabia and stayed in Khorasan up until the
Mongol invasion of that province, at which point they fled to
Yazd. The dynasty was nevertheless closely connected with the Mongols: the mother of
Mubariz al-Din Muhammad, the founder of the dynasty, was almost certainly Mongol. His queen was the
Khitan princess Qutlughkhan Makdumshah, daughter of
Qutb al-Din Shah Jahan, ruler of the
Qutlugh-Khanids. His son
Shah Shoja's queen was a Mongol princess from one of the non-Muslim Mongol tribes of
Kerman, the
Avḡāni and
Jormāʾi. This union produced three Moẓaffarid princes, as well as the princess Pādšāh Solṭān. Serving under the Il-Khans, they gained prominence when Sharaf al-Din Muzaffar was made governor of
Maibud. He was tasked with crushing the robber-bands that were roaming around the country. Sharaf al-Din's son,
Mubariz al-Din Muhammad, was brought up at the Il-Khan's court but returned to Maibud upon the death of the Il-Khan
Öljeitü. In around 1319 he overthrew the
atabeg of
Yazd and was subsequently recognized as governor of the city by the central
Il-Khan government. Following this he began fighting against the Neguderis, a Mongol tribal group. He managed to face this crisis with a minimum of loss. In the wake of the loss of Il-Khan authority in central Iran following the death of
Abu Sa'id Bahadur Khan, Mubariz al-Din continued to carry out his expansionary policy. In 1339 or 1340 he invaded the province of
Kirman and seized it from its Mongol governor, Qutb al-Din b. Nasir. Kutb al-Din was able to retake the province for a short time after receiving aid from the
Kartid dynasty of
Herat, but Mubariz al-Din permanently gained control of Kirman in late 1340. The city of
Bam was besieged and conquered a few years after this. ,
Chobanids and Muzaffarids in 1353 After the conquest of Kirman, Mubariz al-Din became a rival of the neighboring
Injuids, who controlled
Shiraz and
Isfahan. Although the Muzaffarids and Injuids had traditionally been on friendly terms with one another, the Injuid
Abu Esshaq's desire to gain Kirman led him to start a drawn-out conflict with the Muzaffarids in 1347. He unsuccessfully besieged Yazd (1350–1351), after which his fortunes declined rapidly. Defeated on the field in 1353, Abu Esshaq was forced to take refuge in Shiraz and finally surrender. He managed to escape from Shiraz and fled to Isfahan, but Mubariz al-Din pursued him, took the city and executed the Injuid ruler. Fars and western Iran were now under his control. 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 make him a 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. Mubariz al-Din was known as a cruel ruler, and soon afterwards 1358, his son
Shah Shoja blinded and imprisoned him. A temporary reconciliation was reached, but it failed to last and he died, again in prison, in 1363. ==Reign of Shah Shoja==
