She has been called Henry I's favorite sister. She was born c.1067, a year before Henry, and so was close to him growing up, receiving a similar education. She was probably educated at the Abbey of Sainte-Trinité, a Benedictine nunnery in Caen founded by her father. (Her mother would be buried there after her death in 1083.) Although she would not be in a position to inherit anything from her father, her parentage made her a valuable political asset as a bride.
About her 15th birthday, therefore, she was married at Chartres Cathedral to the son and heir to Count Theobald III of Blois, Stephen-Henry. Stephen-Henry was well into his 30s at the time. The marriage linked two powerful families of northern France. They had several children, a few of whom (William, Theobald, and Philip) are seen in the above illustration with their mother.
Stephen became Count of Blois at his father's death in 1089. When the First Crusade was announced, Stephen became one of tis leaders, using money from Adela. He was present at the Siege of Nicaea, writing letters to Adela about the events. His later actions were less than noble, a fact that disturbed his wife deeply and caused her to mock him.
Adela was regent whenever he was away, showing his trust in her and her administrative ability. She made grants to build new churches, and worked with St. Ivo, Bishop of Chartres, concerning misbehavior of nuns. She made sure her children were educated, since they were likely to have illustrious political careers—except, of course, for the ones she wanted to see enter Holy Orders, like her youngest, Henry, whom she dedicated to a religious life.
She became ill in 1105, and was visited by Anselm, the Archbishop of Canterbury, currently exiled to the continent because of disputes with Adela's brother, Henry. In their conversations, Anselm made clear that excommunication of Henry was a possible next step to force Henry to comply with Anselm's demands for church autonomy. It is believed that she had a large part in convincing Henry to work with Anselm instead of against him.
She retired in 1120 to a prestigious convent at Marcigny near Cluny Abbey, where her son Henry was living. She died in 1137. Her financial support of churches and her devotion caused her to be named a saint.
Her persuasion of her brother to work with Anselm was a continuation of her support for the Church. Let us return to Anselm's story tomorrow.
