One community · several governments

You are represented at more than one level.

Choose a level to explore its institutions. The cards show scope, not a chain of command from the president down to your mayor.

United States

Federal government

Three branches with distinct powers

Legislative · makes laws

Congress

Both chambers ordinarily must agree on the same bill.

Executive · carries out laws

President & administration

The president does not run Congress or the courts.

Judicial · decides cases

Federal courts

Simplified court path; specialized courts and other routes also exist.

Checks work across branches.President → can veto a billCongress → can override a vetoSenate → confirms federal judgesCourts → can find laws unconstitutional
A separate government for each state

State government

Its own constitution, offices, and courts

Legislative

State legislature

Usually two chambersOften called House/Assembly and Senate

Nebraska has one chamber. State lawmakers serve in state government, separately from Congress.

Executive

Governor & state agencies

Other state officialsSome elected separately; selection varies

State responsibilities include programs such as licensing and public health; many responsibilities are shared.

Judicial

State courts

Highest state court
Appeals & trial courtsNames and structures vary

Judges may be elected or appointed under state-specific rules. State courts are not branches of the federal district courts.

An orientation, not a complete state directory. Court structures, titles, terms, and selection systems must be checked state by state.

Organized under state law

Local government

Several overlapping kinds of government

County or equivalent

County government

Board or commissionSets local policy and budgets
Executive or managerArrangement varies by place

May administer elections, records, health services, and other county responsibilities.

Municipality

City, town, or village

CouncilLocal legislative decisions
Mayor and/or managerExecutive roles vary by charter

May handle services such as local streets, zoning, and public safety. Cities are not simply departments of counties.

Special purposes

School & special districts

Boards or trusteesElected or appointed under local rules

May govern schools, water, transit, or other specific services. Boundaries can differ from city and county lines.

These are parallel examples of local arrangements, not three branches that every locality has. Your address may place you in several jurisdictions at once.

Levels and branches answer different questions.

Level: Is this federal, state, or local government? Branch: Within a government, does this institution make laws, carry them out, or decide cases?

Federal and state governments share power under the Constitution. Local authority comes from state law. Tribal nations have a distinct sovereign status; they are not a rung beneath local government. D.C. and territories also have distinct arrangements.
