The Catholic Mary Stuart became Queen of Scots at just six days old. She was betrothed to the son of Henry VIII, the future Edward VI, in order to secure peace between England and Scotland. However, her Catholic supporters protested and the match was broken. Mary was later married to the Dauphin Francis and through this match became Queen of France. On his death, Mary returned to Scotland and married Lord Darnley which resulted in the birth of a son, James. A series of Roman Catholic plots against Elizabeth I finally persuaded the Protestant English Queen to order Mary’s execution in 1587. As Elizabeth died childless, Mary’s son James became King James I of England and VI of Scotland.
