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.
Cassandane Cassandane or Cassandana (Ancient Greek: Κασσανδάνη "Kassandanē") was an Achaemenian Persian noblewoman and the "dearly loved" wife of Cyrus the Great. She was a daughter of Pharnaspes. She bore four children for Cyrus (may be 5 based on the documented children listed under Cyrus the Great): Cambyses II, who succeeded his father and conquered Egypt; Smerdis (Bardiya), who also reigned as the king of Persia for a short time; a daughter named Atossa, who later wed Darius the Great; and another daughter named Roxana.
