The Glorious Revolution in England, which occurred in 1688, was primarily about the transition of power from King James II to William of Orange and his wife, Mary II. This political upheaval aimed to resolve ongoing tensions between the monarchy and Parliament, particularly regarding issues of religious tolerance and governance. James II, a Catholic, faced opposition from predominantly Protestant factions within Parliament and the public. The revolution established constitutional monarchy principles, emphasizing parliamentary sovereignty and limiting monarchical power. It led to the Bill of Rights in 1689, ensuring civil liberties and the separation of powers in governance.
