Henry VI, aged nine months, is shown being placed in the care of the
Earl of Warwick
Henry was the only child and heir of King Henry V. He was born on 6 December 1421 at
Windsor Castle. He succeeded to the throne as
King of England at the age of nine months upon his father's death on 31 August 1422; he was the youngest person ever to succeed to the English throne. A few weeks later on 21 October 1422 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 senior
regent of the realm and was in charge of the
ongoing war in France. During Bedford's absence, the government of England was headed by Henry V's other surviving brother,
Humphrey, Duke of Gloucester, who was appointed
Lord Protector and Defender of the Realm. His duties were limited to keeping the peace and summoning Parliament. Henry V's half-uncle
Bishop of Winchester (after 1426 also
Cardinal), had an important place on the Council. After the Duke of Bedford died in 1435, the Duke of Gloucester claimed the Regency himself, but was contested in this by the other members of 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.
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
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 on 16 December 1431.
 It was not until 13 November 1437, shortly before his 16th birthday, that he obtained some measure of independent authority,
 but his growing willingness to involve himself in administration became apparent in 1434 when the place named on writs temporarily changed from
Westminster (where the
Privy Council was) to
Cirencester (where the king was).
 He finally assumed full royal powers when he came of age.
