How did the constitution change American history?

The Constitution of the United States created a form of government known as federalism. The national and state governments each has specific powers and functions while also sharing some of the same powers. The Constitution made any laws passed under the Constitution, the supreme law of the land. Three separate branches were created, the legislative, executive, and judicial. Each branch had specific powers while also having the ability to check the powers of the other two branches. The national government was given the power to tax and to enforce its laws. It created a judicial system in which the Supreme Court of the United States would have the final say as to the constitutionality of laws. A system of checks and balances tied the three branches of government together under the Constitution and the legislature became a truly representative body representing the people. An important feature of the Constitution was that it could be amended to change with the times. The Articles created a confederation of independent states, not a nation. Under the Constitution, the balance of power shifted to the federal government.
