Question

What’s the difference between unitary, confederate, and federal government?

Answer 1

A unitary system of government, or unitary state, is a state governed by a single entity. A confederate government system is a relationship (sometimes loose) between a smaller number of political units. More of an agreement than anything. Finally a federal government is a system that divides power between a strong national government and smaller local government.

All three of these are completely different things.
