Khadija Begi Agha was the daughter of Amir Muhammed Sariq, a local nobleman of little significance. She was given as a concubine to the
Timurid harem of Abu Sa'id Mirza. She had a daughter named Aq Begim. The Timurid dynasty broke
Islamic law about
slavery in islam which dictated that the sex slaves (
concubines) of Muslims should always be slaves. Most of the women of the Timurid dynasty, wives as well as concubines, are only fragmentary known, and Khadija Begi Agha are one of few awknowledged to have had any political influence. When Abu Sa'id Mirza died in 1469, his successor sultan Husayn Bayqara also took her as his concubine. He appear to have done this because of personal attraction or emotional infatuation, since it was not the tradition for a Timurid ruler to take his predecessors concubines, nor did she come from an influential family that could provide any political advantage. In 1471, she gave birth to her first son, Shah-Grarib (1471-1497), and afterward the sultan married her. This was not the custom or because of any political advantage but was described as unique. ==Sultan wife==
