Adela of Normandy

Adela of Normandy, of Blois, or of England, also known as Saint Adela in the Catholic Church, was a daughter of William the Conqueror and Matilda of Flanders. She later became the countess of Blois, Chartres, and Meaux by marriage to Stephen II of Blois. Her husband greatly benefited from the increased social status and prestige that came with a marriage into such a wealthy and powerful family. She was regent of Blois during the absence of her spouse in 1096–1100 and 1101–02, and during the minority of her son from 1102 until 1120. Her marriage also laid the groundwork for a period of extended strife in the Anglo Norman lands. Adela was the mother of King Stephen of England whose taking of the throne in preference to her niece Empress Matilda led to the civil war known as The Anarchy.
