Mary I reigned as Queen of England from 1553 to 1558 — the first woman to rule England in her own right. Daughter of Henry VIII and Catherine of Aragon, she restored papal authority and burned approximately 280 Protestants at the stake, earning the posthumous nickname "Bloody Mary" from Protestant writers who shaped her historical reputation.
How did Mary become queen?
When Edward VI — Henry VIII's Protestant son — died in July 1553 aged fifteen, a group of Protestant nobles attempted to place Lady Jane Grey on the throne to prevent a Catholic succession. Jane Grey ruled for only nine days before Mary, who had substantial popular support, marched on London and took power. Her successful accession demonstrated that many English people, regardless of their religious views, recognised her legitimate claim as Henry's eldest daughter. Jane Grey was imprisoned and later executed, a decision Mary delayed but eventually agreed to after a rebellion.
What changes did Mary make to religion?
Mary's primary goal was to return England to the Catholic Church and papal authority after two decades of religious upheaval — her father's break with Rome, Edward's aggressive Protestant reforms and the dissolution of the monasteries. Her steps included:
- Repealing the Protestant religious legislation of Edward VI's reign.
- Restoring papal supremacy — England once again submitted to the Pope in Rome.
- Reinstating the heresy laws, which made it a capital offence to deny Catholic doctrine.
- Beginning proceedings against leading Protestant clergy and laity.
Cardinal Reginald Pole — a cousin of Mary's — returned from exile to serve as Archbishop of Canterbury and help implement the restoration. What Mary could not recover was the monastery lands distributed to the nobility during the dissolution: those who had benefited from Reformation property sales were not willing to give them back, and Mary chose not to force the issue.
Who was burned and why does it matter for evaluating sources?
Between February 1555 and November 1558, approximately 280 people were burned at the stake for heresy — a figure substantially higher than in any comparable period in English history. Among them were:
- Thomas Cranmer (March 1556): Archbishop of Canterbury under Henry VIII and Edward VI, who had written the Anglican Book of Common Prayer. Cranmer initially recanted his Protestant beliefs under pressure, then publicly withdrew his recantation at the stake and held his right hand — with which he had signed the recantation — into the fire first.
- Hugh Latimer and Nicholas Ridley (October 1555): prominent Protestant bishops burned together in Oxford.
John Foxe's Actes and Monuments (1563) — known as Foxe's Book of Martyrs — documented these burnings in vivid and deliberately harrowing detail, with illustrations. It became one of the most widely read books in Elizabethan England and shaped Protestant memory of Mary's reign for centuries. A historian using Foxe as a source must recognise that it was a piece of Protestant propaganda, written in the reign of Protestant Elizabeth I, designed to portray Mary's victims as heroic martyrs and Mary as a tyrant — it is not a neutral record, though many of its factual details have been corroborated by other evidence.
What else happened during Mary's reign?
Mary married Philip II of Spain in July 1554 — a politically significant match that allied England with the dominant Catholic power in Europe but was deeply unpopular with many English people who feared Spanish domination. Philip was given the title "King of England" but had limited real authority, and the match produced no children. England was dragged into Philip's war against France, with the consequence that in January 1558 England lost Calais — the last English territory on the French mainland, held since 1347. Mary reportedly said that when she died, "Calais" would be found written on her heart. She died in November 1558, probably of influenza or uterine/ovarian cancer, and was succeeded by her Protestant half-sister Elizabeth.
How should we judge Mary's reign?
Historians have increasingly challenged the "Bloody Mary" stereotype, not to excuse the burnings but to complicate the picture. Mary was an intelligent, determined ruler who successfully claimed her throne against serious opposition. The burning of heretics was standard practice across Catholic and Protestant Europe: Calvin's Geneva burned Servetus; Lutherans executed Anabaptists; Henry VIII burned Protestants and Catholics alike. What made Mary's burnings distinctive was their number and concentration in a short period — and the fact that they were recorded by Protestant writers who survived to shape posterity's judgement. Elizabeth I's later execution of Catholics for treason rarely receives the same moral scrutiny. Students should ask why some acts of religious violence are remembered so prominently and others are not.
Frequently asked questions
Why is Mary called "Bloody Mary"?
The name comes from Protestant sources, especially Foxe's Book of Martyrs, and became entrenched during the reign of Elizabeth I when Protestantism was re-established. It reflects Protestant memory of Mary's burnings but is a polemical label, not a neutral historical judgement. Some historians prefer "Mary Tudor" or "Mary I" to avoid loading the name with inherited Protestant bias. The cocktail named "Bloody Mary" appears to take its name from the queen, though the drink's origins are disputed.
What does Mary's reign tell us about religious change in Tudor England?
Mary's reign shows that the Reformation in England was neither inevitable nor irreversible. Large parts of the population, clergy included, accepted or welcomed the return to Catholicism. The monasteries could not be restored — too much property had changed hands — but church practices, clergy and papal authority returned. It was only after Mary's death and Elizabeth's long Protestant reign that Protestantism became deeply embedded in English identity. This matters for understanding why historians debate whether England was ever a genuinely Protestant country before Elizabeth I.
What happened to Protestant exiles during Mary's reign?
Many prominent Protestants, knowing that their views put them at risk, fled to Protestant cities in Europe — Frankfurt, Geneva, Zurich and Strasbourg. These "Marian exiles" encountered continental Calvinism and brought more radical Protestant ideas back to England when Elizabeth I came to power. The exile community thus had a significant long-term effect on the shape of English Protestantism, making it more Calvinist than Henry VIII's original Reformation had been.
Was Philip II really King of England?
Philip II had the title "King of England" during his marriage to Mary (1554–58), but the marriage treaty restricted his authority. He could not make appointments or wage war without Mary's agreement; if Mary died childless, his title expired. Philip spent relatively little time in England and was primarily focused on his vast Spanish empire. After Mary's death he briefly considered marrying Elizabeth to maintain the English alliance, but she declined. Philip later launched the Spanish Armada against Elizabeth in 1588, making the marriage to Mary a historical irony.
