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.
