The Constitution is the highest law in the United States. All other laws come from the Constitution. It says how the government works. It creates the Presidency. It creates the Congress. It creates the Supreme Court. Each state also has a constitution. The constitutions of the states are their highest law for that state — but the United States Constitution is higher.

​

The Constitution can be changed. The Constitution is changed by an "amendment." Among the amendments is a list of the rights of the people. By listing these rights, they are made special. It is illegal for the government to violate those rights. As of 2006, there are 27 amendments. Not all of them involve rights, but many do. The first ten amendments are special. They are called the Bill of Rights.
