Total rule by a king would be an absolute monarchy. In an absolute monarchy, the king or queen has all political power.
Magna Carta,
1. In an absolute monarchy only the people selected by the ruler are allowed to participate in the government. 2. In an absolute monarchy one person, the ruler, has the power to make decisions. 3. Majority rules does not exist in an absolute monarchy. Minority rule and one-person rule exist in an absolute monarchy. (I COPIED THIS FROM MY TEXTBOOK)
An absolute monarchy is the model of government that features rule by one person. In a constitutional monarchy, the monarch's powers are limited instead of absolute.
