Unitary and Federal systems essential questions:
The US and United Kingdom have different systems of government. Explain how the UK’s national government differs from the US national government.
What type of government does every US state have? Unitary or Federal? And how does that relationship between the state and local governments compared with the state and national governments?
Thinking question: How did the United States path to independence impact the system of government that was created in 1787 (Ultimately, I’m asking why do you think we don't have a Unitary National government?)

Federalism is a mixed or compound mode of government that combines a general government (the central or "federal" government) with regional governments (provincial, state, cantonal, territorial or other sub-unit governments) in a single political system. Its distinctive feature, exemplified in the Constitution of the United States, is a relationship of parity between the two levels of government established.[1] Federalism is thus a form of government in which powers are divided between two levels of government of equal status
