Which Amendment reserves powers not explicitly granted to the federal government?

The Tenth Amendment is the provision in the United States Constitution that reserves powers not explicitly granted to the federal government for the states and the people. Ratified in 1791, it serves as a crucial part of the Bill of Rights and emphasizes the principle of federalism, which delineates a clear delineation of authority between the national and state governments. By confirming that powers not delegated to the federal government by the Constitution are reserved to the states or the people, the Tenth Amendment provides a safeguard against the expansion of federal power and underscores the idea that sovereignty resides at both the national and state levels. This reflects the framers’ intention to limit the central government's authority and protect state rights, ensuring a balance in governance.
