Within a monarchy, the royal family holds the power. Typically, the king and or queen.
The difference between absolute monarchy and constitutional monarchy is that in the absolute monarchy, the monarch holds the supreme or absolute powers, whereas in the constitutional monarchy, the head of state is a hereditary or elected monarch
Constitutional Monarchy.
In an absolute monarchy, only the monarch has power, so everyone other than the monarch has no power. In a constitutional monarchy, who is deprived of power depends entirely on the constitution in question.
The main difference between absolute monarchy and constitutional monarchy is that in an absolute monarchy, the monarch has absolute control and power, whereas, in a constitutional monarchy, the power of the monarch is limited by the constitution. Monarchy is a form of governance in which a single person acts as the head of state.
In a constitutional monarchy, like in England, the monarch does not have much power at all, because there is a constitution. In an absolute monarchy, they have absolute power. In a constitutional monarchy, the power of the monarch is limited by some set of rules or document (e.g. a constitution), which sets out the powers given to the monarch. Other powers are given to other groups, commonly judges and a legislature. How much power is given to each group and the monarch varies widely, and is entirely up to the constitution of the country in question. In an absolute monarchy, the monarch is presumed to be God-(or other deity)-ordained, and rules with no limits on their power.
Because the monarch has no real power and is just a figurehead.
In an absolute monarchy, there is no limit on the power of the ruler. A constitutional monarchy imposes certain limits on the ruler's power. In the UK, the monarch's role is largely ceremonial.
Constitutional monarchy is a kind of democratic government where the non-party political head of state is the monarch. The monarch makes the rules and holds formal reserve power while the government takes place in the monarch's name.
A absolute monarchy means the monarch acts as the sole power of authority for the state. In a constitutional monarchy, the monarch acts as head of state, but is bound by a set of rules or constitution which limit their power in some way. Constitutional monarchies often have a parlimentary system, and sometimes (but not always) the monarch plays largely a ceremonial role. Constitutional monarchies have also co-existed in facist states.
In a constitutional monarchy, there is a division of power between the reigning monarch and an elected legislative body. The power of the monarchy is inherited through direct bloodline descent from the previous monarch. The power of the legislative body is derived from popular elections and the power is transferred from one elected official to the next. Both the monarch and the elected officials are granted power during a ceremony in which they take solemn vows relevant to their responsibilities.
In an absolute monarchy, the king has complete power over society. In a constitutional monarchy, the king only has as much power as the constitution grants him. In some places, like Morocco, the constitutional monarch is very powerful, but not quite absolute. In some places like Britain, the constitutional monarch is so weak that it is practically an irrelevancy.
