In keeping with Safavid tradition, Bahram Mirza was given the governorship of many provinces, under the supervision of a guardian who held the real authority. In 1530, he succeeded his brother
Sam Mirza as governor of
Herat, with Ghazi Khan Takkalu as his guardian. In the spring of 1532, an
Uzbek army under
Ubaydallah Khan laid siege to Herat. The main reason the Iranian army was able to endure this protracted siege was because they were provided with food by Uzbeks who disliked Ubaydallah Khan. As a result, in October 1533, Ubaydallah Khan lifted the siege and withdrew. The following month, Shah Tahmasp I reached Herat, where he had Bahram Mirza and Ghazi Khan Takkalu replaced with Sam Mirza, who had Aghzivar Khan Shamlu as his guardian. Over the ensuing years, Bahram Mirza participated actively in the
war with the
Ottoman Empire who had invaded Iran. He took part in the clashes in the
Azerbaijan province in 1534, and the next year he pressured the Ottoman soldiers that attempted to retake the Iranian territory they had briefly occupied in 1534. In 1536/37, Shah Tahmasp I attempted to extend Safavid control by taking advantage of the death of the
Kar-Kiya ruler of eastern
Gilan, Soltan-Hasan Kiya. He appointed Bahram Mirza as the governor of Gilan and gave him the task of imposing Safavid authority with the help of a sizable army. During his brief time as governor, Bahram Mirza encountered strong opposition; as mass uprisings started, he fled to
Qazvin. According to the modern historian Colin P. Mitchell; "This probably did not make a favourable impression on his older brother". His next known appointment as governor was in 1546, when he succeeded
Abdollah Khan Ustajlu as the governor of
Hamadan, with Cheragh Soltan Gerampa Ustajlu as his guardian. Bahram Mirza played a key-role in dealing with the rebellion of his brother
Alqas Mirza, who invaded mainland Iran with Ottoman support. In 1548, while Bahram Mirza was away, Alqas Mirza raided Hamadan and captured his family, whom he had sent to
Baghdad (they later returned after Alqas Mirza's death). Alqas Mirza and his soldiers were soon chased across central Iran by Bahram Mirza in coordination with Ibrahim Dhu'l-Qadar, the governor of
Shiraz. In 1549 at the town of
Marivan, Alqas Mirza surrendered to Bahram Mirza. He was taken to the court of Shah Tahmasp I, who had him imprisoned in the
Qahqaheh Castle. Bahram Mirza died during this period, on 11 October 1549 in one of the villages of the
Kurdistan province, possibly due to an overdose of
opium. He was buried in
Mashhad. On 9 April 1550, Alqas Mirza was killed by being thrown from the castle. == Cultural patronage ==
