A constitution is a system of managing a nation's government, that usually spells out how the government is to be structured and the rules the government must follow. A constitution is usually written, but not always.
Alternatively, a constitution is the fundamental law of a nation or state which establishes the character and basic principles of the government. In the United States, both the nation and each state have constitutions. Each state's government is bound by both the limitations on its powers set forth in its state constitution and the limitations on the powers of the states set forth in the United States Constitution
