Henry VI of England in accordance with the Treaty of Troyes of 1420, he became titular King of France upon his grandfather Charles VI's death. His mother, Catherine of Valois, was then 20 years old. As Charles VI's daughter, she was viewed with considerable suspicion by English nobles and was prevented from playing a full role in her son's upbringing. On 28 September 1423, the nobles swore loyalty to Henry VI. They summoned Parliament in the King's name and established a regency council to govern until the King should come of age. One of Henry V's surviving brothers, John, Duke of Bedford, was appointed
Henry VI of England the Council. From 1428, Henry's tutor was Richard de Beauchamp, Earl of Warwick, whose father had been instrumental in the opposition to Richard II's reign. Henry's half-brothers, Edmund and Jasper, the sons of his widowed mother and Owen Tudor, were later given earldoms. Edmund Tudor was the father of Henry Tudor, who later became Henry VII. In reaction to Charles VII's coronation as French King in Reims Cathedral on 17 July 1429, Henry was soon crowned King of England at Westminster Abbey on 6 November 1429, followed by his own coronation as King of France at Notre Dame de Paris
