In a constitutional monarchy, the monarch's power is limited by a constitution, which is a set of laws that define the powers and duties of the monarch and the government.

In an absolute monarchy, the monarch has absolute power, meaning that they can make and enforce laws without the consent of the people or any other governing body.

The United Kingdom, Canada, Australia, and New Zealand are all examples of constitutional monarchies.

Saudi Arabia, Oman, Qatar, and the United Arab Emirates are all examples of absolute monarchies.

Constitutional monarchies offer a number of advantages, including stability, protection of citizen rights, and the ability to make peaceful changes in government.

Constitutional monarchies can also have some disadvantages, such as the cost of maintaining the monarchy, the slow pace of change, and the difficulty of holding the monarch accountable.

Absolute monarchies do not offer any real advantages over other forms of government. They are often inefficient, unstable, and do not protect the rights of citizens.

Absolute monarchies have a number of disadvantages, including the potential for oppression and tyranny, corruption and abuse of power, and the stifling of economic growth and development.

Constitutional monarchies are more common in the world today than absolute monarchies.

It is impossible to say what the future of monarchy will be. It is possible that it will continue to exist in some form, or that it will eventually be replaced by other forms of government.
