Charles I Executed for Treason in London
Amid the English Civil War, deep divisions over royal authority, religion, and parliamentary rights pitted King Charles I against his opponents. Parliamentary forces captured the king after years of conflict and established a special High Court of Justice to try him. On January 30, 1649, Charles was taken to a scaffold outside the Banqueting House in Whitehall, London, where he delivered a brief address asserting his innocence before an executioner beheaded him with one blow. The public execution of a reigning monarch sent immediate shockwaves through Britain and Europe. It directly led to the abolition of the monarchy and the creation of the Commonwealth of England under Oliver Cromwell.
