Explanation:

states’ rights, the rights or powers retained by the regional governments of a federal union under the provisions of a federal constitution. In the United States, Switzerland, and Australia, the powers of the regional governments are those that remain after the powers of the central government have been enumerated in the constitution. In contrast, the powers at both the state or regional level and the national level of government are defined clearly by specific provisions of the constitutions of Canada and Germany.

The concept of states’ rights is closely related to that of state rights, which was invoked from the 18th century in Europe to legitimate the powers vested in sovereign national governments. Doctrines asserting states’ rights were developed in contexts in which states functioned as distinct units in a federal system of government. In the United States, for example, Americans in the 18th and 19th centuries often referred to the rights of states, implying that each state had inherent rights and sovereignty. Before and following the American Civil War (1861–65), the U.S. states—particularly the Southern states—shared the belief that each of them was sovereign and should have jurisdiction over its most important affairs. By the end of the 20th century, the term was applied more broadly to a variety of efforts aimed at reducing the powers of national governments, which had grown considerably in both size and scope.
