What are the three parts of the Constitution?

The United States Constitution was ratified in 1788 and enacted in 1789. It is divided into the following three parts:

I. Preamble: The Preamble is brief and serves to state the purpose of the Constitution.

II. Articles: There are seven articles which lay out basic information about how the government will function. They include the responsibilities of the legislative, executive, and judicial branches, as well as the process for amending the Constitution.

III. Amendments: There are now 27 amendments to the Constitution. The first ten amendments were added in 1791 and comprise the Bill of Rights. The Constitution was last amended in 1992 with the 27th Amendment, which stipulated that if Congress passes a law that gives itself a raise, it will not actually be implemented until after the next election cycle.

The Equal Rights Amendment was passed by Congress in 1972 but was not ratified by enough states to become law.
