States rights can best be defined as the belief that states?

States' rights can best be defined as the belief that individual states hold certain rights and powers that the federal government cannot infringe upon. This principle emphasizes the autonomy of states in matters of governance, law, and policy, often advocating for local decision-making over federal mandates. Historically, it has been a contentious issue, particularly in contexts such as slavery, civil rights, and education. Proponents argue that states are better equipped to address the unique needs of their populations.
