Demographics
Religion
The primary religious belief in the area now is Shi‘ite Islam. Sangesar was a Zoroastrian stronghold after the invasion of Islam. The Zoroastrians were prosecuted and forced to convert, but much of Sangesari customs have roots in Zoroastrian traditions. Before the Islamic Revolution, a major segment of the population became followers of the Baháʼí Faith in Sangsar. The Bahais migrated from Sangesar to Tehran after the revolution, due to a wide range of persecutions. As for other towns of Iran, the name has thus been changed by the Islamic Republic authorities into Mehdishahr to punish the locals and to signal its imposed pure Muslim identity. Since Bahais believed that the savior, Bab (Mehdi) had appeared, the Islamic Republic renamed Sangesar to Mehdishahr. Mehdi is the Shia Muslim hidden Imam / Savior and Shahr means town in Persian, so Mehdishahr literally means the town reclaimed by Mehdi. Sangesar population who are ancient Persians and proud of their heritage have resisted this change and continue calling their city Sangesar and they continue speaking the ancient Sangesari language.
