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.
Judith of Bavaria (died 843) Queen Judith (797– 19 April 843), also known as Judith of Bavaria, was the daughter of Count Welf of Bavaria and Saxon noblewoman, Hedwig. She was the second wife of Louis the Pious, King of the Franks and Emperor of the Romans, which brought her the titles of queen and empress. Marriage to Louis marked the beginning of her rise as an influential figure in the Carolingian court. She had two children with Louis, a daughter Gisela and a son, Charles the Bald. The birth of her son led to a major dispute over the imperial succession, and tensions between her and Charles' half-brothers from Louis' first marriage. She would eventually fall from grace when Charles' wife, the new empress Ermentrude of Orléans, rose to power. She was buried in 846 in Tours.
