Answer:
The answer is the principle of federalism.
Explanation:
For a long time, the best organization for the leadership of the countries has been sought, for which different political movements have been developed, since the formation of the constitution, of the states, and the models of federalism, centralism, among others.
In some countries such as Canada, Brazil, or the United States, they are governed by the principles of federalism in their political methods, through which the entire nation is divided into states that work independently. However, despite the freedom of each state, the general laws are linked and governed under the same executive, legislative, and judicial powers.
With the incorporation of the principles of federalism into the constitution, it was determined that the nation would hold the supreme power; that is, it would be over the power of the states.
