The Bill of Rights of 1689 was one of the results of the Glorious Revolution 1688-1689. It was rooted in tensions between Protestants and Catholics and also between Parliament and King James II, who was ousted in favor of his Protestant daughter Mary and William of Orange -- a joint monarchy. The document uses the concepts of liberty, legality and consent, among others.
The english who realized Glorious Revolution and produced the Bill of Rights were demanding that royal power was based not in divine rights but in consent from the Parliament.

From now on kings and queens should reign following limits legally created by the Parliament, which should always exist and be composed of elected representatives.
