The government of the United States is a massive and complex organization. Its purpose is to improve and protect the lives of American citizens, both at home and overseas. The federal government is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the U.S. Constitution in the Congress, the President, and the federal courts, respectively. The United States government is also a constitutional government. It operates according to a set of laws and principles that are outlined in a constitution. And, it is an example of the federal system of government. This means that the national government shares responsibilities with the state and municipal governments. The purpose of our Federal Government, as found in the Preamble of the Constitution, is to "establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our posterity."
