Who reestablished Catholicism in England was Mary I.
After the Protestant Reformation, led by Martin Luther, the Counter-Reformation of the Catholic Church was contemporaneous with the rise of Mary to the reign of England.
The first measure of Mary in 1554 was to re-establish Catholicism and reconcile England with the pope. At the same time, the Catholic sovereign undertook a persecution of Protestants, which earned her the epithet "Mary, the bloodthirsty."
