Henry was the only child and heir of King Henry V of England. He was born on 6 December 1421 at Windsor, and succeeded to the throne at the age of eight months as King of England on 31 August 1422, when his father died, and King of France on 21 October 1422 upon his grandfather Charles VI's death in agreement with the Treaty of Troyes in 1420. His mother, Catherine of Valois, was then 20 years old and, as Charles VI's daughter, was viewed with considerable suspicion and prevented from having a full role in her son's upbringing.
