The claim is too sweeping as written. It is true that the post-1688/1689 settlement established a more clearly defined constitutional monarchy: the Bill of Rights made the monarch govern only with Parliament’s consent and firmly established frequent parliaments, free elections, and parliamentary privilege. But it is not accurate to say that this produced a system of government that “we all understood” in any universal or settled sense. UK Parliament’s own material describes the 1688–89 arrangements as a pragmatic agreement, while the Commons Library notes that the origins, nature, and extent of parliamentary sovereignty are complex and disputed, and that constitutional government became durable through later habit rather than because revolution had finally settled everything.
