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.
Empress Wei (Tang dynasty) Empress Wei (韋皇后, personal name unknown) (died July 21, 710) was an empress of the Chinese Tang Dynasty. She was the second wife of Emperor Zhongzong, who reigned twice, and during his second reign, she tried to emulate the example of her mother-in-law Wu Zetian and seize power. After Emperor Zhongzong's death in 710—a death traditionally believed to be a poisoning she carried out together with her daughter Li Guo'er the Princess Anle—which gave her the power to become the empress dowager, but in short order was overthrown and killed in a coup led by Emperor Zhongzong's nephew Li Longji (the later Emperor Xuanzong) and Emperor Zhongzong's sister Princess Taiping.
