The Constitution of the United States

The Constitution of the United States is the supreme law of the United States of America.[1]The Constitution, originally comprising seven articles, delineates the national frame of government. Its first three articles entrench the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislative, consisting of the bicameral Congress; the executive, consisting of the President; and the judicial, consisting of the Supreme Court and other federal courts. Articles Four, Five and Six entrench concepts of federalism, describing the rights and responsibilities of state governments and of the states in relationship to the federal government. Article Seven establishes the procedure subsequently used by the thirteen States to ratify it.

Since the Constitution was put into effect in 1789, it has been amended twenty-seven times. The first ten amendments are known collectively as the Bill of Rights. At seven articles and twenty-seven amendments, it is the shortest written constitution in force.

The Constitution is interpreted, supplemented, and implemented by a large body of constitutional law. The Constitution of the United States was the first constitution of its kind, and has influenced the constitutions of other nations.
