Mary I of England, also known as Mary Tudor, was the daughter of Henry VIII and Catherine of Aragon. She became queen in 1553 and ruled until her death in 1558. Mary is best known for her attempt to restore Roman Catholicism in England after her father had established the Church of England. During her reign, she earned the nickname "Bloody Mary" due to her persecution of Protestant reformers. Her efforts to reverse the Protestant Reformation led to the execution of many dissenters. After her death, her half-sister, Elizabeth I, ascended the throne, further solidifying Protestantism in England.
