As a devout Catholic, Mary began to restore the status of Catholicism in England as soon as she came to power. She abolished the laws and systems of Edward VI and restored the old system and etiquette. Britain immediately reconciled and resumed diplomatic relations with the Holy See. Mary I also used force to suppress the White Rebellion launched by the Protestants. Those who called for the continuation of the Reformation were dismissed by Mary I as "obscene and corrupt ideas." In November 1554, Catholic Cardinal Pole, who had been in exile for a long time, returned to England, and Mary I immediately appointed him Archbishop of Canterbury. In February 1555, Mary I and Paul reinstated heretic trials and burnings. After that, they vigorously suppressed the Protestants. During the five years of Mary I's reign, more than 200 Protestants were burned to death. Even Henry VIII's crony, the former Archbishop of Canterbury, Kramer, was burned at the stake in 1556. Mary I was known as "Bloody Mary" for her harsh suppression of Protestants.
