Haydar Mirza Safavi

Haydar Mirza Safavi (, also spelled Haidar Mirza Safavi) was a Safavid prince, who declared himself as the king (shah) of Iran on 15 May 1576, the following day after his father Tahmasp I had died. He was, however, during the same day killed by the Qizilbash tribes that favored his brother Ismail Mirza Safavi as the successor of their father. His mother was Sultanzadeh Khanum, a Georgian lady. Biography Haydar Mirza was born on 18 September 1554 to Tahmasp I and Sultanzadeh Khanum, a Georgian lady. His mother was a sister of the Georgian converts Aman Beg (an influential nobleman) and Ali Khan Beg. On 18 October 1574, Tahmasp I became ill—during his illness, he was close to dying two times, and he still hadn't chosen a successor. Thus the main chieftains of the Qizilbash arranged a meeting to discuss about who should be the successor. The Ustalju clan, and the Shaykhavand clan (which was related to the Safavid family) favored Haydar Mirza. The Georgians also supported him, since his mother was Georgian.
