The United States Constitution was adopted in 1787 as a foundational governing document following the American Revolution. It established the framework for the federal government, outlining the separation of powers among the legislative, executive, and judicial branches. The Constitution addressed the shortcomings of the Articles of Confederation and emphasized the principles of federalism, checks and balances, and the protection of individual rights, which were further elucidated in the Bill of Rights. This document remains a cornerstone of American democracy, embodying the ideas of liberty, justice, and the rule of law, and has influenced numerous other nations.
