The accounts in "Mino Khirad", written during the Savafid period, demonstrate that the Zoroastrians were subjected to harassment by the Shi'ite majority, their places of worship were under a constant threat of being destroyed. By 1707, when Le Bruyn visited Isfahan, the Zoroastrians were no longer able practice their religion freely. He notes that the most deprived Zoroastrians had been brought to Isfahan, and had been forced to become Muslim three years earlier. In 1821, Ker Porter visiting Isfahan notes that there were hardly any Zoroastrians left in Isfahan and Gabrabad was in ruins.
