Over time, the Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the federal government playing a much larger role than it once did. There is a continuing debate over states' rights, which concerns the extent and nature of the states' powers and sovereignty in relation to the federal government as well as the rights of individual persons.
Congress may admit new states on an equal footing with existing ones; this last happened in 1959 with the admission of Alaska and Hawaii. The Constitution is silent on the question of whether states have the power to leave unilaterally, or secede from, the Union, but the Supreme Court has ruled[3][4] secession to be unconstitutional, a position driven in part by the outcome of the American Civil War.
