20 points explain the similarities and differences between the monarchy and constitutional monarchy

The main difference between absolute monarchy and constitutional monarchy is that in the absolute monarchy, the monarch holds the absolute powers, and in the constitutional monarchy, the head of state is a hereditary or elected monarch. Absolute monarchy is also called undemocratic monarchy because monarch has total power, whereas constitutional monarchy is called a liberal monarchy because the king or queen has limited powers since they rule along side with a parliament or another governing body. An absolute monarch is not legally bound whereas a constitutional monarch is legally bound by the constitution of his country. In constitutional monarchies the governing body makes economic and foreign affair policies as well.  In the constitutional monarchy, the prime minister of the state holds the maximum powers and political effectiveness which is the case in the UK. Absolute monarchs were initiated due to holy wars and the decline of the church, but were soon proven as innefective and that is how constitutional monarchy came to be.
