US (United States) Constitution is the supreme law of the United States of America. This founding document, originally comprising seven articles, delineates the national frame of government.
Its first three articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches:
- Article I : The legislative, consisting of the bicameral Congress
- Article II : The executive, consisting of the president and subordinate officers
- Article III: The judicial, consisting of the Supreme Court and other federal courts .
Article IV, Article V and Article VI embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment.
Article VII establishes the procedure subsequently used by the 13 States to ratify it. It is regarded as the oldest written and codified national constitution in force.Download PDF of US Constitution from loc.gov using the direct download link given below.
