In the early 16th century the great Safavid king, Shah Abbas I settled a number of Zoroastrians in a suburb of his new capital, Isfahan. The suburb of Isfahan where the Zoroastrians lived was called Gabr-Mahal, Gabristan or Gabrabad, derived from the word Gabr. Europeans who visited his court left accounts of the 'Gabars' or 'Gabrs', (an insulting term used for Zoroastrians by the Muslims), agree on the poverty and simplicity of their lives. Fearing desecration by Muslims, Zoroastrians hid the sacred fires, and conversed in a newly invented dialect called Dari. Later Safavid kings were not as tolerant as Shah Abbas. Muhammad Baqir Majlisi persuaded Sultan Husayn (1688–1728 CE) to decree the forcible conversion of Zoroastrians, those who refused were killed.
