Queen Elizabeth I was the daughter of King Henry VIII and his second wife, Anne Boleyn. When Elizabeth was three years old, Henry had Anne beheaded and their marriage declared invalid, thus rendering Elizabeth an illegitimate child and removing her from the line of succession (to which Parliament would later restore her). Two of Elizabeth’s half-siblings sat on the throne after Henry’s death in 1547: Edward VI, who acceded at the age of nine and died six years later; and Mary I, who operated under the belief that Elizabeth was trying to seize power from her for the entirety of her own five-year reign. When Elizabeth was crowned monarch in 1558, her lack of a husband and heir became one of the defining issues for the remainder of her rule. As the end of her life approached, she forestalled the successional crisis that might otherwise have arisen by designating King James VI of Scotland as the next in line to the throne. The rule of the Tudor dynasty ended with the death of Elizabeth.
