Mary's claim to the throne and arrival in England (Edexcel GCSE History): Revision Notes
Mary, Queen of Scots: her claim to the throne and arrival in England

Mary, Queen of Scots represented one of the most significant threats to Elizabeth I's reign. Her legitimate bloodline claim to the English throne made her a focal point for Catholic opposition and international intrigue during the early years of Elizabeth's rule.
Mary's genealogical claim to the English throne
Mary Stuart possessed a strong hereditary claim to the English throne through her Tudor ancestry. She was the great-granddaughter of Henry VII, making her Elizabeth I's second cousin. This connection came through Margaret Tudor, Henry VIII's sister, who had married into the Scottish royal family.
Mary's legitimacy was particularly significant because, unlike Elizabeth, there were no questions surrounding the validity of her parents' marriage. While some Catholics questioned Elizabeth's legitimacy due to doubts about Henry VIII's marriage to Anne Boleyn, Mary's royal bloodline was uncontested.
Born in 1542, Mary became Queen of Scotland when she was just six days old. During her youth, she was sent to France where she married Francis II, briefly making her Queen of France as well as Scotland. However, Francis's death in 1560 ended this union and prompted Mary's return to Scotland.
The Catholic dimension of Mary's claim
Mary's Catholic faith transformed her from merely a rival claimant into a symbol of Catholic resistance against Protestant England. This religious aspect made her claim particularly dangerous for several reasons.
Many English Catholics, especially among the nobility, viewed Mary as their rightful queen. They saw Elizabeth as illegitimate and believed that England should return to Catholicism under Mary's rule. This created a ready-made support network for any potential uprising or invasion.
Mary's presence provided foreign Catholic powers, particularly France and Spain, with a legitimate candidate to support in their efforts to restore Catholicism to England. Her claim gave international credibility to any plots against Elizabeth's government.
Mary's troubles in Scotland and departure in 1568
Mary's personal life created the political crisis that ultimately led to her flight to England. After returning to Scotland as a widow, she married Henry Stuart, Lord Darnley, in 1565. This marriage produced a son, James, born in 1566, who would later become James VI of Scotland and James I of England.
However, Darnley's murder in 1567 created a major scandal, particularly when Mary quickly married the Earl of Bothwell, who was widely suspected of orchestrating Darnley's death. Many Scots believed Mary was complicit in her husband's murder, and this suspicion destroyed much of her support.
Key Events Leading to Mary's Downfall:
Step 1: Mary marries Lord Darnley (1565)
- Produces heir James (1566)
- Marriage becomes troubled
Step 2: Darnley is murdered (1567)
- Earl of Bothwell suspected
- Creates major scandal
Step 3: Mary marries Bothwell (1567)
- Scots believe she was complicit in murder
- Loses support of Scottish lords
Step 4: Forced abdication and military defeat
- Protestant lords rebel
- Battle of Langside (May 1568) - Mary defeated
The Protestant Scottish lords rebelled against Mary, forcing her to abdicate in favour of her infant son James. When Mary attempted to regain her throne by raising an army, she was decisively defeated at the Battle of Langside near Glasgow in May 1568.
Mary's arrival and imprisonment in England
Following her military defeat, Mary made the fateful decision to flee to England, seeking help from her cousin Elizabeth I. She arrived in England in May 1568, expecting Elizabeth's support in regaining her Scottish throne.
However, Mary's presence in England created an enormous dilemma for Elizabeth. The Scottish Queen represented both an opportunity and a threat. While Elizabeth could not simply hand Mary back to her Scottish enemies, keeping her in England posed significant risks.
Elizabeth decided to hold Mary under comfortable but secure guard while considering her options. The English government recognised that Mary's presence encouraged Catholic hopes for rebellion. Many Catholics believed they could overthrow Elizabeth and place Mary on the English throne.
Mary's imprisonment effectively removed Elizabeth's most legitimate rival while avoiding the diplomatic crisis that executing or extraditing a fellow queen would have caused. However, this solution also meant that Mary remained a focal point for Catholic conspiracies throughout the following decades.
