Mary I of Scotland (Hapsburg's Unite)

Mary I (December 14, 1542 - July 24, 1567 & September 5, 1582 - October 20, 1585) became Queen of Scotland on December 14, 1542, and then again on September 5, 1582 at the ages of 6 days and 40 respectively. Mary's mother was Mary of Guise, while her father was James V. Mary was the eighth Stewart to be crowned Queen of Scotland.

Mary was forced to abdicate once, though with the help of Henry IX of England she forced herself back onto the throne, though not long after she was assassinated by a group of Scottish Protestants loyal to her son, James.
