Francis became king as Francis I on January 1, 1515, and Claude became queen of France. She was crowned at Saint-Denis in May 1517. Claude had seven children in about eight years, including the future Henry II. She lived a quiet, pious life while Francis pursued his wars and his mistresses. Among the young women in her household was Anne Boleyn, who served her for several years. Brittany was formally united with France in 1532. Claude was crowned Queen of France at St. Denis Basilica on 10 May 1517 by Cardinal Philippe de Luxembourg (also known as Cardinal du Mans), who "anointed her in the breast and forehead". Claude died on 26 July 1524 at the Château de Blois, aged twenty-four. The exact cause of her death was disputed among sources and historians: while some alleged that she died in childbirth or after a miscarriage, others believed that she died for exhaustion after her many pregnancies or after developing bone tuberculosis (like her mother) and finally some believed that she died from syphilis caught from her husband. She was buried at St. Denis Basilica. The available biographical account does not describe a continuous final medical course. It gives no dependable sequence of treatment and last symptoms from which to reconstruct a more detailed bedside narrative.
