What are the main differences between unitary, confederal, and federal systems of government? How is this different from the distinctions we make among democratic, monarchical, autocratic, and oligarchic systems of government?

A unitary government is composed of a very strong central government which holds the authority and makes decision for weaker smaller states.

A federal government is a system that divides up power between a strong central government, weaker states and smaller local governments, while a confederal system involves a group of states that unite under one "weak" central government with its states having more powers.

These forms of government systems are different from the systems mentioned below due to the fact that it deals with the way and manner a state's resources is being divided. Therefore, who gets what and who contributes what. They are majorly about resource control and not the manner or style of government in itself,
