Absolute Monarchy
The king had absolute power that came from God itself, this was called his divine right.
He had no powers above him, he unified the three powers of the State: executive, legislative and judiciary.
There were not citizens but subjects, they had no rights. However, nobility and clergy had some privileges.
Although the king had absolute power he was helped in his duties by secretaries and councils. He also had parliaments for relevant matters, but they were rarely called together. Absolute kings avoided them.
