Article V of the U.S. Constitution outlines the process for amending the Constitution. This article is crucial because it establishes how the Constitution can evolve over time through formal amendments, ensuring that it remains relevant and responsive to changing societal needs. It details two methods for proposing amendments: either by a two-thirds vote in both the House of Representatives and the Senate or by a national convention called by two-thirds of state legislatures, followed by ratification from three-fourths of the states.
