The Constitution of the United States is the supreme law of the United States of America. The Constitution originally consisted of seven Articles. The first three Articles embody the doctrine of the separation of powers, whereby the federal government is divided into three branches: the legislature, consisting of the bicameral Congress; the executive, consisting of the President; and the judiciary, consisting of the Supreme Court and other federal courts. The fourth and sixth Articles frame the doctrine of federalism, describing the relationship between State and State, and between the several States and the federal government. The fifth Article provides the procedure for amending the Constitution. The seventh Article provides the procedure for ratifying the Constitution.
The Constitution was adopted on September 17, 1787, by the Constitutional Convention in Philadelphia, Pennsylvania, and ratified by conventions in eleven States. It went into effect on March 4, 1789.
A constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed. These rules together make up, i.e. constitute, what the entity is. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a written constitution; if they are written down in a single comprehensive document, it is said to embody a codified constitution.
