The Glorious Revolution was a significant event in English history that took place in 1688. It involved the overthrow of King James II and the ascension of William of Orange and his wife Mary II to the throne. This revolution was largely bloodless and marked a shift in power from the monarchy to Parliament, establishing the principle of constitutional monarchy. The Glorious Revolution was driven by concerns over James II's Catholicism and his attempts to promote religious tolerance for Catholics. The event led to the Bill of Rights in 1689, which limited the powers of the monarchy and laid the foundation for a more democratic government in England.
