What is a key principle outlined in the Tenth Amendment?

The Tenth Amendment, ratified in 1791 as part of the Bill of Rights, emphasizes the principle of federalism by reserving powers that are not explicitly granted to the federal government by the Constitution for the states and the people. This means that any power not specifically mentioned in the Constitution as being under federal authority is assumed to fall under state jurisdiction. This principle is crucial because it protects the states' rights, allowing them to legislate and govern in various areas like education, transportation, and law enforcement, as long as they do not conflict with federal laws. By asserting the reserved powers to states, the Tenth Amendment establishes a balance of power between state and federal entities, thereby preventing an overreach by the federal government into areas of local governance.
