The Act of Settlement is an Act of the Parliament of England that settled the succession to the English and Irish crowns to only Protestants, which passed in 1701. More specifically, anyone who became a Roman Catholic, or who married one, became disqualified to inherit the throne. This had the effect of deposing the remaining descendants of Charles I, other than his Protestant granddaughter Anne, as the next Protestant in line to the throne was Sophia of Hanover. Born into the House of Wittelsbach, she was a granddaughter of James VI and I from his most junior surviving line, with the crowns descending only to her non-Catholic heirs. Sophia died shortly before the death of Queen Anne, and Sophia's son succeeded to the throne as King George I, starting the Hanoverian dynasty in Britain.

The Parliament of England was the legislature of the Kingdom of England from the 13th century until 1707 when it was replaced by the Parliament of Great Britain. Parliament evolved from the great council of bishops and peers that advised the English monarch. Great councils were first called Parliaments during the reign of Henry III. By this time, the king required Parliament's consent to levy taxation.
