What is the difference between an absolute monarchy and a representative estate?

She differs in that the king with her has unlimited power. In fact, he alone leads the state. The estate-representative monarchy limits the power of the king to the existence of other authorities. If we take Kievan Rus, then for a long period there existed an early feudal monarchy, and the power of the Grand Duke was essentially not limited. So the prince concentrated judicial power in his hands, and also issued laws.
