Tenth Amendment to the United States Constitution
The Tenth Amendment to the United States Constitution, a part of the Bill of Rights, was ratified on December 15, 1791. It expresses the principle of federalism, also known as states' rights, by stating that the federal government has only those powers delegated to it by the Constitution, and that all other powers not forbidden to the states by the Constitution are reserved to each state, or to the people.

United States Bill of Rights
The United States Bill of Rights comprises the first ten amendments to the United States Constitution. Proposed following the often bitter 1787–88 debate over the ratification of the Constitution and written to address the objections raised by Anti-Federalists, the Bill of Rights amendments add to the Constitution specific guarantees of personal freedoms and rights, clear limitations on the government's power in judicial and other proceedings, and explicit declarations that all powers not specifically granted to the federal government by the Constitution are reserved to the states or the people. The concepts codified in these amendments are built upon those in earlier documents, especially the Virginia Declaration of Rights (1776), as well as the Northwest Ordinance (1787), the English Bill of Rights (1689), and Magna Carta (1215).
