The Mihrabanids were often vassals of their more powerful neighbors. The Mihrabanids assumed control of Sistan in the wake of its subjugation by the
Mongols. After the foundation of the
Ilkhanate by
Hulegu Khan in 1256 the maliks recognized the Ilkhans as their overlords. Under the Ilkhans, Sistan's distance from the capital gave the Mihrabanids a high degree of autonomy. During this time they intermittently fought against the
Kartid maliks of
Herat, who were also Ilkhanid vassals, and had replaced them in eastern Persia. By 1289, all of Quhistan had been conquered by the Mihrabanids, with Nasir al-Din Muhammad giving it to his son Shams al-Din 'Ali as an appanage. After the Ilkhanate's collapse in the mid-14th century the Mihrabanids were independent for almost half a century. This independence was ended by
Timur, who invaded Sistan in 1383 and caused extensive devastation to the province. The Mihrabanids henceforth were Timurid vassals until the latter's overthrow by the
Shaybanids in the first decade of the 16th century. The last malik of the dynasty decided to recognize the authority of the
Safavids, eventually handing over control of Sistan and ending the Mihrabanids' governance of the region. Both the Mihrabanids and the general population of Sistan were Sunni Muslims. In the early 16th century Malik
Sultan Mahmud became a
Safavid vassal; as a result certain
Shi'i religious practices were introduced, such as the Shi'i
call to prayer. This transition was disliked by many of the people of Sistan. ==Mihrabanid maliks==
