Passed under the Reformation Parliament of Henry VIII, this act further secured the position of Henry VIII as head of the Church of England, which had broken away from Roman rule in 1533. Following the Act in Restraint of Appeals in 1533, which gave the monarch authority to control the organisation of the church, the Act of Supremacy attributed spiritual leadership to the King, appointing him Supreme Head, a title later terminated by Queen Mary I. First fruits and tenths of all benefices are granted to the Crown, and the King is authorised to appoint suffragan bishops. Acts of Attainder are brought against Sir Thomas More and Bishop Fisher of Rochester for misprision and against the Earl of Kildare for treason.
