Queen Elizabeth I of England, who reigned from 1558 to 1603, was known for her strict enforcement of Protestantism. As a Protestant monarch, she sought to consolidate her authority and establish a national church, the Church of England, while suppressing Catholic practices and dissent. Her reign was marked by the enforcement of the Elizabethan Religious Settlement, which aimed to create a moderate Protestantism that avoided extremes. Religious persecution occurred, particularly against Catholics, ensuring that her vision of a Protestant nation was realized. Elizabeth's policies helped to solidify Protestantism in England for generations.
