What was read out at the coronation of William and Mary?
A Declaration of Rights.
William and Mary did not simply inherit the throne; Parliament invited them in. So at their coronation a Declaration of Rights was read aloud, setting out the new limits on royal power. It was the opening move in a long game: from now on the monarch would rule with Parliament, not over it.
Test Trap. the Declaration of Rights (read at the coronation) is often confused with the Bill of Rights, 1689 (the law passed afterwards). Coronation = Declaration; law = Bill.
Why it matters: The test likes to ask what happened at William and Mary's coronation, and the Declaration is easily mixed up with the Bill of Rights that followed it.
Memory hook: Picture the crown going on while someone reads a list out loud: Declaration first, Bill of Rights later.
