Edward Seymour, Duke of Somerset, is beheaded for treason. On the death of Henry VIII in 1547, he had seized power for himself and designated himself Lord Protector of young king Edward VI. However, his rule was toppled by a council-led coup d'etat in October 1549 after a serious popular rebellion, and he had been in the Tower of London ever since.
