Sultan Husayn (sŏltänˈ hōsānˈ) [key], d. 1729, Safavid shah of Persia (1694–1722). A weak and superstitious man, Shah Sultan Husayn was surrounded by astrologers and fanatics and was able to offer little opposition to the uprising of the Afghans. He gave up his throne, and the bloody rule of Mahmud followed. Persian administration was restored only later by Nadir Shah.
