Unveiling the 27 Pillars of American Democracy: A Concise Guide to U.S. Constitutional Amendments
Explore the evolution of American rights and governance through one-sentence summaries of each constitutional amendment.
The United States Constitution, the bedrock of American law and governance, was established on March 4, 1789. It is a living document, designed to adapt to the changing needs and values of the nation. This adaptability is achieved through amendments, formal changes to the Constitution's text. Over more than two centuries, twenty-seven amendments have been ratified, each reflecting a significant shift or clarification in American society, law, or governmental structure. The process for amending the Constitution, outlined in Article V, is rigorous, requiring proposal by a two-thirds majority in both houses of Congress or by a national convention called for by two-thirds of state legislatures, followed by ratification by three-fourths of the states. This intricate process ensures that only amendments with broad support become part of the nation's foundational law.
