The Constitution of the United States is the foundation of our Federal Government. It is often called the supreme or highest law of the land; no law may be passed that contradicts its principles. At the same time, it is flexible and allows for changes in the Government. The Constitution is known as a “living” document because it can be amended, although in over 200 years there have only been 27 amendments.

The Constitution is organized into three parts. The first part, the Preamble, describes the purpose of the document and Government. The second part, the seven Articles, establishes how the Government is structured and how the Constitution can be changed. The third part, the Amendments, lists changes to the Constitution; the first 10 are called the Bill of Rights.

The Founding Fathers established three main principles on which our Federal Government is based:

• Inherent rights, or rights that anyone living in America has
• Self-government, or Government by the people
• Separation of powers, or branches of Government with separate powers

After the American Revolutionary War (1775-1783), the states were functioning under the Articles of Confederation, but the Articles provided little guidance to the states. In September of 1786, there was a meeting in Annapolis, MD, where representatives from New York, New Jersey, Delaware, Virginia, and Pennsylvania met to see what they could do about trade barriers set up among the states. The system of government set up by the Articles of Confederation did not regulate trade among states and needed to be changed.
