David upheld his support for his niece, the former Empress-consort, who had how many children?
England and King David I The relationship between the Kingdom of England and King David I, who was King of Scotland between 1124 and 1153, was partly shaped by David's relationship with the particular King of England, and partly by David's own ambition. David had a good relationship with and was an ally of Henry I of England, the King who was largely responsible for David's early career. After Henry's death, David upheld his support for his niece, the former Empress-consort, Matilda, and expanded his power in northern England in the process, despite his defeat at the Battle of the Standard in 1138.
Dugu Qieluo Dugu Qieluo (; 544 – September 10, 602), formally Empress Wenxian (文獻皇后), was an empress of the Chinese Sui dynasty. She was the wife of Emperor Wen, who, on account of his love and respect for her, as well as an oath they made while they were young, did not have any concubines for at least most of their marriage and might not have had any concubines while she was alive, an extreme rarity among Chinese emperors. She was powerful and influential during her husband's reign, and she was heavily involved in his decision to divert the order of succession from their oldest son Yang Yong to the second son Yang Guang (later Emperor Yang), often blamed by traditional historians to be the reason for Sui's downfall.
