| rowspan="10" | The United States Constitution is the shortest in history and therefore is rather vague. When it went into effect, it enumerated many powers of the federal government and recognized some rights guaranteed to the people, however, there was ambiguity about the powers and rights that were not mentioned in the document. Many people were worried that the federal government would take all the powers not mentioned in the Constitution and infringe the people's rights that were not specified in the document. The Bill of Rights cleared up some of that ambiguity by specifying rights that could not be violated by Congress and indicated that all powers not mentioned in the Constitution belonged to the states. It was passed by Congress just six months after the Constitution went into force and was ratified two years later. The Bill of Rights helped to unify the new union of states and kept the country together for more than 60 years.
