Taj al-Dawlah

Taj al-Dawlah (Persian: تاج‌الدوله), born as Khojasta Jahanbani, was a member of the Qajar dynasty, royal consort and wife of Naser al-Din Shah Qajar of Iran.

She, possibly born 1834/1833, was the daughter of Prince Seyfollah Mirza Jahanbani. Naser al-Din Shah's second legal and permanent wife, she was the mother of Prince Moin ad-Din Mirza, heir to the throne until his death at the age of 7, as well as Princess Ismat al-Doulah.

She got selected and proposed by the royal family high-ranks in 1848 to marry the new Shah of Iran, who was also considered her distant cousin, just months after his ascension to the throne in Tehran. She was the first ever permanent wife Naser al-Din Shah married after he became the monarch, (having already another wife, Galin Khatun, whom he married to when he still was a prince).

After Naser al-Din Shah's assassination and reformation of the Qajar harem in 1896 when she was in her 60s, she left the palace and remarried.
