By Dec. 15, three-fourths of the states ratify the Bill of Rights, the first 10 amendments to the Constitution. The amendments are meant to secure individual liberties and to maintain the balance of power between the federal government and the states. The 10th Amendment states that powers not delegated to the federal government belong to the states. Although not specified in the 10th Amendment, the U.S. Supreme Court rules in years to come that laws affecting family relations, commerce within a state’s borders, and local law enforcement fall within state authority.
