Explore King Henry VIII’s groundbreaking act and its far-reaching consequences.

The Act of Supremacy of 1534 declared Henry VIII the supreme head of the Church of England, formally rejecting the authority of the Roman Catholic Church. Primarily a political manoeuvre to grant Henry the power to annul his marriage to Catherine of Aragon, the act made it treason to support the Pope's authority.
