Following the death of Abu Sayed Behauder in 1335, the Muzaffarid governor of Yazd, Mubarriz Al-Din Muhammad, took first Kerman. then Shiraz in 1350, and Isfahan in 1354, in the process putting to death the last of the Inju clan which had formerly held the area, Sheikh Abu Ishaq. He was an orthodox muslim who banned the sale of alcohol and treated his sons so harshly that he was eventually blinded and imprisoned by two of them. Mubarriz Al-Din arranged for the marriage of Abu Ishaq's niece, Soltan Bakht Agha, to one of his sons, Qutb Al-Din, who initially held Isfahan and who was responsible for the area in the Masjed-e-Jomeh known as the Porch of Omar. His wife determined to avenge her uncle's death and formented discord between her husband and his brother, Jalal Al-Din. Her plotting came to the ears of her husband who had her executed but still lost control of Isfahan in 1375 to Jalal Al-Din, who initially sided with the advancing Timur and this guaranteed Isfahan's safety during his lifetime. Under Jalal Al-Din the great monument on the right was erected to Soltan Bakht Agha which can be seen to this day.
After Jalal Al-Din's death in 1384 his son Mujahid Al-Din Zayn Al-'Abidayn, rashly decided to take on Timur who replaced him as governor of Isfahan with relatives more sympathetic to Timur. As soon as Timur left however the family feud was rekindled, Mujahid Al-Din was blinded and imprisoned by his brother and, fed up with the whole lot, Timur returned in 1393 and executed every remaining Muzaffarid prince!
The great Iranian poet Hafez, who celebrated the opening of the wine-shops closed under Mubarriz Al-Din Muhammad, and who is reported to have told Timur that he would exchange Timur's empire for a mole on the cheek of his beloved, wrote of the Muzaffarids as follows:
"Like the house of Inju before them, the sun of this dynasty shone out brightly, but speedily passed from view" - translated in Honarfar, p.36.
