United States is the world's oldest federation. It is a constitutional republic and representative democracy, "in which majority rule is governed by minority rights protected by law." The government is regulated by a system of checks and balances defined by the Constitution, which serves as the country's supreme legal document.

In the American federalist system, citizens are usually subject to three levels of government: federal, state and local, the local government's duties are commonly split between county governments and municipalities. In almost all cases, officials of the executive and legislative branches are directly elected by citizens of the district. The constitution of the United States is in force since its inception.
