Mary Tudor, also known as Mary I of England, was born on February 18, 1516. She was the daughter of Henry VIII and his first wife, Catherine of Aragon. Mary became queen in 1553 and is often remembered for her efforts to restore Roman Catholicism in England after her father had established the Church of England. Her reign, which lasted until 1558, was marked by religious persecution, leading to the execution of many Protestants, earning her the nickname "Bloody Mary." Despite her efforts, her policies were largely unpopular, and she was succeeded by her half-sister, Elizabeth I, who reinstated Protestantism.
