Edward Seymour, Lord Protector, was executed in 1552, after the Earl of Warwick, later Duke of Northumberland, took over affairs of state and Seymour was convicted of felony in plotting to bring down Warwick's regime. Northumberland did not last long; after the death of Edward VI he put his daughter in law Jane Grey on the throne. When the Privy Council had a change of heart and proclaimed Mary Tudor as queen, he lost his head.
