Mary Queen of Scots

As the title suggests, Mary, Queen of Scots was the ruler of Scotland between 1542 and 1567. It was a title she received by birth as her predecessor and father, James V, died only six days after her birth, reportedly due to a fever or nervous breakdown after his army lost the Battle of Solway Moss.

Mary also served as the Queen consort of France for a short period after her first marriage to Francis II, King of France. According to The School Run, she used her power to ensure Queen Elizabeth I’s downfall but was forcefully abdicated in 1967 after being accused of adultery and murder. She died 20 years later.
