It is the other way round, Elizabeth 1st of England imprisoned Mary, Queen of Scots, in the Tower of London. However, to ask why she did this, is in debate, as many people could argue over that is was because Mary was plotting against Elizabeth, or the other way round.
Queen Elizabeth I (1533 - 1603) was locked up in the Tower of London in March 1554 for 8 weeks, (when she was still Princess Elizabeth) on the orders of her half sister, Mary I (1516 - 1558). Mary was suspicious of Elizabeth and thought she might be the inspiration for plots against her. When Mary I died in 1558, Elizabeth became Queen.
Imprisonment of Princess ElizabethThe Imprisonment of ElizabethThe Wyatt Rebellion implicated Elizabeth in the conspiracy. Questioned by Stephen Gardiner at Whitehall she vehemently denies any involvement in the plot to overthrow her Catholic sister Mary. Although there is no proof to the charges Mary refuses to see Elizabeth so she can plead her innocence and the decision is made to imprison Elizabeth in the Tower of London. Elizabeth is absolutely terrified and enters the Tower of London on March 18, 1554 via Traitors Gate, beneath St Thomas's Tower, believing that she will die in the fortress. She was imprisoned in the Bell Tower.
If you mean Mary I of England (Mary Tudor), she wasn't executed. She died of cancer on November 17, 1558. If you mean Mary, Queen of Scots (Mary Stewart), she was executed by her cousin Elizabeth I (Elizabeth Tudor) on February 8, 1587.
Mary Queen of Scots had been deposed and fled Scotland, going to England seeking shelter. Since she had always claimed that Elizabeth I was illegitimate and that she, Mary, was the rightful queen, Elizabeth told her she had to give up that idea if she wanted protection. Mary refused, so Elizabeth had her put in confinement. Mary was imprisoned for 19 years, but finally was implicated in plots to overthrow Elizabeth. Parliament insisted that Mary be executed, and Elizabeth complied. Whether Mary was actually guilty of plotting we will never know. Nor will we know whether Elizabeth was actually reluctant to have her executed, as it is claimed.
Mary had imrosioned her step sister in the tower because Mary was a catholic and she had heard that her half sister had consipred to over throw her.(Elizabeth was a protestant)
Queen Elizabeth I was a Queen of England. Elizabeth II is a Queen of the United Kingdom, which includes England, but also several other counties. Both are descended from King Henry VII. Henry was the grandfather of Elizabeth I and the 13th great grandfather of Elizabeth II. Elizabeth I and Elizabeth II are First cousins, 13 times removed,
Queen Elizabeth I was imprisoned in the Tower of London for at least a year because her half-sister, Mary I ( AKA Mary Queen of Scots), suspected her of helping to create and knowing in advance about a plan to steal the throne.
As Elizabeth had Mary put to death it can be assumed that their relationship was not the best. If the question refers to Elizabeth I and Mary I, then above answer is incorrect. Mary I possibly died of ovarian cancer, she was not executed. Regarding the relationship between the sisters, I guess you could say it was complicated. When Henry VIII annulled his marriage to Mary's mother (in benefit of Elizabeth's mother) Mary lost her title as princess and place in line of succession to her half-sister. Also, when the sisters were older, they had disagreements regarding religion, as Mary was a Catholic and Elizabeth a Protestant. During Mary's time as Queen, Elizabeth was suspected of conspiring against her and was imprisoned in the Tower. However, she was later released.
She was a threat to her Catholic faith. Elizabeth was more popular than Mary.
Until near the end, it was more of a house arrest. Elizabeth moved Mary to the Tower after allegations of Mary's involvement in a plot to assasinate her.
Elizabeth was put there by her sister Mary , who was Queen at the time. Mary had a very bad relationship with Elizabeth ever since she had been born. When Mary came into power she now had the ability to get rid of Elizabeth. It's a shock she was not executed but Mary died before she had the chance to have the princess killed.
Elizabeth Alexandra Mary is her full name.
