The Acts of Supremacy are two acts passed by the Parliament of England in the 16th century that established the English monarchs as the head of the Church of England. The 1534 Act declared King Henry VIII and his successors as the Supreme Head of the Church, replacing the pope. This first Act was repealed during the reign of the Catholic Queen Mary I. The 1558 Act declared Queen Elizabeth I and her successors the Supreme Governor of the Church, a title that the British monarch still holds.
