Article I, Section 10 of the U.S. Constitution

Article I, Section 10 of the U.S. Constitution restricts the powers of individual states to prevent them from engaging in certain actions that could interfere with national unity or federal authority. It prohibits states from entering into treaties, coining money, taxing imports or exports without federal approval, and maintaining armies or ships during peacetime, among other restrictions. These limitations help ensure states do not act independently in ways that could undermine the federal government or disrupt the country’s economic and security stability. Essentially, it defines boundaries for state power to maintain a balanced and functioning union.
