About Kerman Kerman was founded as a defensive outpost, with the name Behdesīr, by Ardeshir I, founder of the Sassanid Empire, in the 3rd century AD. After the Battle of Nahāvand in 642, the city came under Muslim rule. At first the city's isolation allowed Kharijites and Zoroastrians to thrive there, but the Kharijites were wiped out in 698, and the population was mostly Muslim by 725. Already in the eighth century the city was famous for its manufacture of cashmere wool shawls and other textiles. The Abbasid Caliphate's authority over the region was weak, and power passed in the tenth century to the Buyid dynasty, which maintained control even when the region and city fell to Mahmud of Ghazna in the late tenth century. The name Kerman was adopted at some point in the tenth century.
