Mary Tudor was born in 1516 and reigned as Queen from 1553-1558. She was born at Greenwich Palace and was the only child of Henry VIII and Katherine of Aragon to survive childhood.
As Queen, she attempted to reverse the reformation and return England to the Catholic faith. After her death, Protestant writers called her 'Bloody Mary', owing to the number of Protestant 'heretics' she had ordered to be executed.
Elizabeth was born in 1533 and reigned as Queen from 1558-1603. Like her half sister Mary I, Elizabeth was born at Greenwich Palace in London. The only daughter of Henry VIII and his second wife, Anne Boleyn, Elizabeth was only 2 and a half years old when her mother was executed.
After Anne Boleyn's execution, Elizabeth was declared illegitimate and deprived of the title of 'princess'. However before his death in 1547, Henry VIII reinstated both his daughters in the line of succession.
Famous for being the 'virgin queen' as she never married, Elizabeth set England back on the Protestant path after Mary I's attempt to return the country to Catholicism.
Elizabeth was imprisoned in the Tower of London in 1554 by Mary I.
