Biography
The names of two of Yazid's known wives are: Umm Khalid Fakhita bint Abi Hisham. Fakhita and Umm Kulthum both hailed from the Abd Shams, the parent clan of the Umayyads.Fakhitah was the mother of Yazid's younger son Khalid. Her husband came to the throne in 680. Her husband ruled the Caliphate 680 to 683. Her husband Yazid I, had made the 'bay'ah' to his son Mu'awiya. Mu'awiya II succeeded his father in Damascus in 64 AH, at an age of somewhere between 17 and 23. Mu'awiya was the son of another wife of Yazid thus the step-son of Fakhitah. Her step-son's reign would have lasted for about 20 days to 4 months, but likely no more than 2 months. Due to premature death of Mu'awiya II, he died, without nominating a successor.
After Mu'awiya II's death, her son Khalid became a candidate to the Caliphate, however due to his young age in the end, their choice fell on his more experienced kinsman Marwan.
Marwan wed Yazid's widow and mother of Khalid, Umm Hashim Fakhita, thereby establishing a political link with the Sufyanids. Wellhausen viewed the marriage as an attempt by Marwan to seize the inheritance of Yazid by becoming stepfather to his sons.
Fakhitah died during the Caliphate of her step-son Abd al-Malik ibn Marwan.
