Yazd which was a city founded by Yazdgerd I was 240 year old and a center for Zoroastrians when it was conquered by Muslim Arabs. After the Iranian army's defeat in Nahavand in 641 AD, most cities did not show much resistance except for Shooshtar, Rhagae and some southern cities. The Muslims were telling people that they only want to spread Islamic teachings and those promises were very appealing to people for the fact that Iranian social and economic system had not evolved due to status quo and every social reform request like that of Mazdak and Mani had been suppressed brutally. Meanwhile king Yazdgerd 3 was still alive and fighting the enemy here and there until he was assassinated in 651.
