A series of executions of the commissioners who signed the death warrant of Charles I of England concluded; six were hanged, drawn and quartered for treason.

The Regicides of Charles I were the men responsible for the execution of Charles I on 30 January 1649. The term generally refers to the fifty-nine commissioners who signed the execution warrant. This followed his conviction for treason by the High Court of Justice.

Charles I was King of England, Scotland, and Ireland from 27 March 1625 until his execution in 1649.

To be hanged, drawn and quartered was a method of torturous capital punishment used principally to execute men convicted of high treason in medieval and early modern Britain and Ireland. The convicted traitor was fastened by the feet to a hurdle, or wooden panel, and drawn behind a horse to the place of execution, where he was then hanged, emasculated, disembowelled, beheaded, and quartered. His remains would then often be displayed in prominent places across the country, such as London Bridge, to serve as a warning of the fate of traitors. The punishment was only ever applied to men; for reasons of public decency, women convicted of high treason were instead burned at the stake.
