Final answer:
Mary Tudor's efforts to restore Catholicism in England ultimately failed, leading to the reaffirmation of Protestantism under Elizabeth I, who sought a moderate religious policy and reinforced Protestant influence in the country.
Step-by-step explanation:
Instead of ending Protestantism in England, Mary Tudor's actions only contributed to its growth. Mary I, strongly Catholic, sought to return England to the Catholic Church by repealing the legislation that had established the Church of England and executing hundreds of Protestants. Her reign, however, did not accomplish the desired Catholic restoration. Upon her death, her half-sister, Elizabeth I, ascended the throne and reinstated Protestantism, seeking a middle ground between the two faiths. Elizabeth's Protestant policies were moderate, requesting only outward conformity, allowing priests to marry and moving ceremonies to the vernacular. This reinforced Protestantism in England, leading to its stability and the rise of the Puritans who would influence English colonization in the New World.
