Tajlu Khanum

Tajlu Khanum or Tajli Begum (تاجلی بیگم), also known by her title of Shah-Begi Khanum (شاه بگی خانم), was a Turkoman princess from the Mawsillu tribe and mother of Tahmasp I.

Family
While Italian writer Angiolello and Iranian historian Manuchihr Parsaʹdust agree that she was a granddaughter of the Aq Qoyunlu ruler Yaqub (r. 1478–1490) via a daughter, John Woods proposed her paternal lineage as Mihmad Beg being her father and Amir Hamza being her grandfather. Jean Aubin on the other hand, proposed Bakr Beg Mawsillu as her maternal grandfather. She also had a sister named Beksi Khanum.

Marriage
According to Angiolello and Ramusio, the Safavid shah Ismail I (r. 1501–1524) married Tajlu Khanum after defeating the Aq Qoyunlu ruler Murad ibn Ya'qub in 1503, but according to the Safavid-period historians such as Budaq Monshi Qazvini, she was the wife of the Afrasiyabid ruler Kiya Husayn II, who had during the dissolution of the Aq Qoyunlu confederation expanded his rule from western Mazandaran into parts of Persian Iraq. Ismail I invaded the latter's territories and put an end to his rule in 1504, where he afterwards took Tajlu Khanum into his harem. She thereafter become Ismail's most beloved wife.She woas a very beautiful, intelligent,warrior tactful woman , which is why Shah Ismail loved her and wrote great poems for her.Tajlu was te only wife of the king who was skilled in swordsmanship and always accompanied his spouse in his battles and bore him two sons Tahmasp Mirza and Bahram Mirza Safavi and two daughters Parikhan Khanum and Mahinbanu Khanum.

Life in Safavid court
Her supposed capture at Battle of Chaldiran was a major source of controversy among historians of Iran and Ottoman Empire. While Ottoman sources wrote that she was captured during battle and even conversed with Selim I, according to Safavid sources she was lost but found by Mirza Shah Hossein, who because of this rose to the rank of wakil in Safavid court. According to Roger Savory, it was Behruza Khanum, another wife of Ismail I who was captured and apparently later remarried.

Tajlu financed shrine of Fatima al-Masuma in Qom in 1519, supported Tahmasp Mirza's elevation to throne in 1524. But was banished to Shiraz in 1540 because of treason by his son. She later died and buried in Bibi Dokhtaran mausoleum.
