Answer: Federalism
Step-by-step explanation:
Federalism was recognized as aggregate state of government, mixing a federal government with state governments in a well defined political system. Its unique feature, demonstrated in the example of contemporary federalism by the US under its Constitution(1787), is stated as a relationship of equity between two levels of state(government) entrenched. Therefore it can be referred as a state of government where there is a distribution of strength/powers between these two levels of government.
