Act of Supremacy 1558

The Act of Supremacy (1 Eliz 1 c 1), also referred to as the Act of Supremacy 1558, is an Act of the Parliament of England, passed under the auspices of Queen Elizabeth I of England. It replaced the original Act of Supremacy 1534 issued by Elizabeth's father, Henry VIII, which arrogated ecclesiastical authority to the monarchy, and which had been repealed by Mary I of England. Along with the Act of Uniformity 1558 it made up what is generally referred to as the Elizabethan Religious Settlement. (The Acts were actually passed in 1559, but Parliamentary convention was to date Acts according to the year in which Parliament began to sit, rather than the date of Royal Assent.)

The whole Act, so far as unrepealed, except section 8, was repealed by section 1 of, and Part II of the Schedule to, the Statute Law (Repeals) Act 1969.

This Act was partly in force in Great Britain at the end of 2010.
