who was the first woman monarch of england
List of English monarchs Edward VI named Lady Jane Grey as his heir in his will, overruling the order of succession laid down by Parliament in the Third Succession Act. Four days after his death on 6 July 1553, Jane was proclaimed queenâ€”the first of three Tudor women to be proclaimed queen regnant. Nine days after the proclamation, on 19 July, the Privy Council switched allegiance and proclaimed Edward VI's Catholic half-sister Mary queen. Jane was executed for treason in 1554, aged 16.
