Religion - United Kingdom VS United States

Abstract

England & Scotland have an established church: the Church of England (Anglican Church) and the Church of Scotland.
The process started with King Henry VIII, who created the Church of England after his split with the Pope, a few years after Martin Luther had published the Ninety-Five Theses (1517).
The King wanted his marriage annulled in order to marry his mistress, but the Pope refused so Henry passed the Act of Supremacy, which made him Supreme Head of the Church of England.
