Had a legitimate claim to the English throne, was Catholic, and was at the centre of many plots designed to overthrow Elizabeth
Mary was Henry VIII's great-granddaughter and Elizabeth's second cousin
Mary was descended from Margaret Tudor, Henry VIII's sister
Mary was married to the French king, Francis I, and inherited the Scottish crown when she was only six days old
While Mary was in France, her mother, Mary of Guise, ruled Scotland
Why Mary was important
She was Catholic, so Catholics, including members of the nobility, would be prepared to support her claim to the throne
Her claim was strengthened by the fact there were no concerns about her legitimacy, unlike Elizabeth's
Mary would always be at the centre of Catholic plots and conspiracies against Elizabeth, involving both English plotters and foreign powers
Mary leaves Scotland
1. On the death of Francis II in 1560, Mary returned to Scotland and married HenryStuart (Lord Darnley), producing an heir
2. Darnley was subsequently murdered (possibly with Mary's involvement)
3. Mary then married the Earl of Bothwell
Protestant Scottish lords rebelled against Mary, imprisoned her and forced her to abdicate (give up her throne) in favour of her son, James
Mary escaped and raised an army, but this was defeated at Langside near Glasgow
Mary subsequently fled to England, seeking her cousin Elizabeth's help against the Scottish rebels
Mary's imprisonment in England, 1568
Mary was held in England in comfort but under guard while Elizabeth decided what to do with her
The Scottish rebels demanded that Mary be handed over and tried for the murder of Darnley
Mary's arrival in England created a problem for Elizabeth, as she could encourage rebellion, but taking action against her as an anointed monarch would reduce Elizabeth's own status, power and authority
Relations between the two monarchs remained tense, as Elizabeth became increasingly concerned about the threat Mary posed to her throne
Elizabeth's options with Mary, Queen of Scots, in 1568-69
Help Mary to regain her throne
Hand Mary over to the Scottish lords
Allow Mary to go abroad
Keep Mary in England
The Casket Letters Affair
A meeting was set up at York to hear the case against Mary, where the Scottish lords brought love letters supposedly written by Mary to the Earl of Bothwell, showing she had plotted to murder Lord Darnley
Mary said she could not be tried because she was an anointed monarch, and would not offer a plea unless Elizabeth guaranteed a verdict of innocence
The conference did not reach any conclusions, so Mary remained captive in England
By not handing over Mary, Elizabeth ensured the Scottish nobility would not imprison or execute Mary, the French would be satisfied, and her subjects did not punish an anointed monarch
Mary remained a threat to Elizabeth, because any plots against her, especially those involving Catholics, would seek to replace Elizabeth with Mary
Elizabeth did not make Mary her heir, as this would upset English Protestants, including those on her Privy Council, and the prospect of a Catholic heir would result in civil war in the event of Elizabeth's death
