The U.S. Constitution: America's Supreme Law

Grade 5 · Social Studies · Study Guide

Find out how and why the Founders wrote the Constitution and what makes it the most important document in American government.

The United States Constitution is the supreme law of the land. It was written in 1787 at the Constitutional Convention in Philadelphia, Pennsylvania, and went into effect in 1789. The Founders wrote it to replace the Articles of Confederation, which had created a national government so weak it could barely function — it couldn't collect taxes or force states to follow national laws.

The Constitution created three separate branches of government to prevent any one person or group from having too much power. This is called the separation of powers. The Legislative Branch (Congress) makes the laws. It has two parts — the Senate and the House of Representatives — which together form a bicameral legislature. The Executive Branch (the President) carries out the laws. The Judicial Branch (the Supreme Court and federal courts) interprets the laws and decides if they follow the Constitution. A system of checks and balances makes sure each branch can limit the power of the others.

Many Americans worried the Constitution gave the national government too much power over individual rights. So in 1791, the first ten amendments — called the Bill of Rights — were added. These protect freedoms like freedom of speech, religion, and the press (1st Amendment), the right to bear arms (2nd Amendment), and protection against unreasonable searches (4th Amendment). The Constitution can be changed through a process called amendment, and 27 amendments have been added in total. The framers designed it to be a living document that could grow with the nation.
