Adela of Normandy

Adela (c. 1067–1137), a daughter of William the Conqueror, married Count Stephen-Henry of Blois around 1083. She ruled Blois and Chartres as regent during the First Crusade, and after Stephen fell at Ramla in 1102 continued ruling for her son Theobald until 1107.

In 1105 she helped arrange a truce between Henry I of England and Pope Paschal II, and from 1107 governed jointly with Theobald until retiring.

Her son Stephen, raised at her brother's court, seized the English crown in 1135. She retired to Marcigny Priory around 1120 and died there on 8 March 1137.
