Mary I of England (1516–1558), also known as Mary Tudor, was Queen of England and Ireland from 1553 until her death. She was the first queen regnant of England and is best known for restoring Roman Catholicism and for the Marian persecution of Protestants, which earned her the nickname “Bloody Mary.”

Early life

Mary was the daughter of Henry VIII and Catherine of Aragon, born on 18 February 1516. Her status changed after Henry’s annulment from Catherine and remarriage; she was later returned to favour and restored in the line of succession.

Accession and reign

Mary became queen in 1553 after the death of her half-brother Edward VI. She was the first queen regnant of England, ruling in her own right. Her reign focused on reversing Protestant reforms, strengthening Catholic worship, and managing foreign and domestic opposition.

Religious policy

Mary restored Roman Catholicism and revived laws against heresy. Her government restored papal supremacy and Roman Catholic bishops in England. The persecution of Protestants during her reign led to the execution of hundreds of dissenters, shaping her lasting historical reputation.

Marriage and foreign policy

Mary married Philip II of Spain in 1554, creating a politically important but unpopular alliance that linked England to the Habsburg sphere. Her war with France ended in the loss of Calais.

Legacy

Mary’s reign is remembered both for religious persecution and for her role as England’s first reigning queen. Later historians have also noted administrative and naval developments during her government.
