Answer:
The answer is: Federalism.
Step-by-step explanation:
Federalism is a political doctrine that seeks for a political entity or organization to be formed by organizations -states, associations, groups, unions, etc.- that are associated by delegating some freedoms or powers of their own to another higher body, to whom sovereignty belongs -State federated or federation- and that retain a certain autonomy, since some competences belong exclusively to them.
In other words, it is a political system in which the functions of the government are distributed among a group of associated States, first, which then delegate powers to a central federal State.
The answer is: Federalism.
