Succession · monarch of England
Why did Elizabeth I of England succeed Mary I?
Inheritance under the Third Succession Act and Henry VIII's will. Half-sister — both daughters of Henry VIII, by Catherine of Aragon and Anne Boleyn.
The short answer
Mary died childless on 17 November 1558. Elizabeth was next under the 1543 Act and Henry's will, and Mary had acknowledged her as heir shortly before her death. Mary's husband Philip II of Spain had been king consort only; his rights ended with her.
