Tell me about Mary Queen of Scots.

Queen Mary I ruled Scotland from 1542 to 1567. Her father was James V. Although she was the princess of Scotland, she spent most of her childhood in France. In 1558, she married the Dauphin of France, Francis. In 1560, Francis died and left Mary as the Queen of Scotland. She remarried to Lord Darnley and had a child with him but in 1567, he was found murdered in the garden. She then married James Hepburn VI but was imprisoned after an uprising against them. After an unsuccessful attempt to regain the throne, Mary fled to her first cousin, Queen Elizabeth I. Seeing her as a threat, Elizabeth had her confined in various castles. After 18 years in custody, Mary was found guilty of plotting to assassinate the Queen in 1586 and was beheaded in 1587.
