The United States Constitution is the supreme law of the United States. The Constitution, originally comprising seven articles, outlines the national frame of government. Its first three articles embody the doctrine of the separation of powers. Articles Four, Five and Six introduces concepts of federalism, establishing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. Article Seven describes the procedure subsequently used by the thirteen States to ratify it.
