Edward VI did not kill his uncle, Thomas Seymour. Thomas Seymour was executed for treason, but it was not Edward VI who ordered his death. Edward VI was only a child at the time, and the decision to execute Thomas Seymour was made by the Regency Council, which governed England during Edward’s minority.
Thomas Seymour, the brother of Jane Seymour (Henry VIII’s third wife), was accused of plotting to overthrow the government and seize power. He was arrested, tried, and found guilty of treason. The Regency Council, led by Edward Seymour (Thomas’s brother and the Lord Protector), decided to execute him to prevent any further threats to the stability of the realm.
Edward VI, being a minor, had little to no direct involvement in the decision-making process. His role was largely ceremonial, and the real power lay with the Regency Council. Therefore, it is inaccurate to say that Edward VI killed his uncle; rather, it was the political circumstances and the actions of the Regency Council that led to Thomas Seymour’s execution.
