Sultanum Begum was the daughter of Musa Sultan bin ‘Isa Beg Musullu (Bayanduri), of the Aq Quyunlu, governor of Azerbaijan. Like Tahmasp's mother Tajlu Khanum, Sultanum belonged to the Turcoman Mawsillu tribe and was a maternal third cousin of her husband. Tahmasp had most likely married her around the time of his father, Ismail I's death. She became his principal wife and bore him two sons, including Mohammad Khodabanda who was born in 1532, during the early years of the Shamlu-Ustalju regency, when Tahmasp himself was only eighteen years old, and Ismail II, born in 1537.
