Absolute monarchs historically abused their power to make themselves more money while ignoring the needs of their people.
Charles I and the English Civil War
You think I can't have an army? I'll show you!
The Interregnum and Cromwell's Rule
Behead all the Irish!
Historically, absolute monarchs abused their power to make more money for themselves while ignoring the needs of their constituents. Parliament was created to protect the rights of the people.
The Restoration and Charles II
Parliament didn't trust Charles I with an army so Charles I created one anyways and started the English Civil War.
The Glorious Revolution
After Charles I was killed for treason, Oliver Cromwell came to power and established a military dictatorship in which he killed many Catholics and Irish. The Parliament in office at the time, Rump Parliament, was overruled.
William and Mary
Charles II was asked back to power by Parliament after the disastrous rule of Cromwell, and Charles II worked well with Parliament at first because of a group of advisors that connected the King to Parliament.
Charles II's son, James II, was chased out of the monarchy because he made the Protestants fear the Catholics. The swap of power to William and Mary was bloodless.
William and Mary took over rule and gladly shared power with Parliament. Together, they enacted a Bill of Rights for England.
