what the constitution

The Constitution of the United States is the supreme law of the country, written in 1787 and ratified in 1788. It has been in operation since 1789 and is the world's longest surviving written charter of government. The Constitution establishes the structure of the government and the rights of the citizens. It consists of a preamble and seven articles that describe the way the government is structured and how it operates. The first three articles establish the three branches of government: the Legislative, the Executive, and the Judicial, and their powers. The Constitution also includes a system of checks and balances to prevent any one branch from becoming dominant. It is interpreted, supplemented, and implemented by a large body of federal constitutional law and has influenced the constitutions of other nations
