Mary I of England

Mary I (February 18, 1516 – November 17, 1558) was the first queen regnant of England, reigning from 1553 until her death. Born to Henry VIII and Catherine of Aragon, Mary's path to the throne was filled with uncertainty and danger. After her father's break with Rome and establishment of the Church of England, Mary was removed from the line of succession and endured years of isolation and danger under her Protestant half-sister Elizabeth. Upon the death of the young Protestant king Edward VI, Mary ascended to the throne and immediately began efforts to restore Catholicism to England, earning her the epithet "Bloody Mary" for her persecution of Protestants during her reign. Estimates of those burned at the stake during her religious campaign vary, but the number reached at least 280. Despite her religious persecution, Mary was an able administrator and attempted to strengthen England's position internationally through marriage to Philip II of Spain. Her reign was marked by military setbacks, including the loss of Calais to the French. Mary's inability to produce an heir—despite believing she was pregnant—meant that upon her death, the crown passed to her half-sister Elizabeth I. Mary's reign remains controversial and significant in English history as a pivotal moment in religious conflict.
