What are 8 governments that apply to us today?

I think this might be it.

The structure of state governments is determined by a state’s constitution. Each U.S. state has its own constitution. The state's constitution establishes the government structures, as well as the limitation of power by the state, and any political issue under its command.

Under the U.S. Constitution, all state governments are modeled after the federal government.

The Tenth Amendment to the United States Constitution states that “all powers not granted to the federal government are reserved for the states and the people.” All state governments consist of three branches: an executive branch –the President- a legislative branch –the Congress-  and the judicial branch, the Court.
