Which document outlines the framework of the U.S. government?

The U.S. Constitution serves as the foundational framework for the government of the United States. It establishes the structure of the federal government, delineating the powers and responsibilities of the three branches: the legislative, executive, and judicial. The Constitution also sets forth the system of checks and balances designed to prevent any one branch from becoming too powerful. It outlines how laws are made, how elections are conducted, and the rights of the citizens. Additionally, it includes the process for amendments, reflecting the document's ability to evolve over time while remaining a stable guiding force for governance.

In contrast, the Declaration of Independence articulates the reasons for the American colonies' separation from British rule but does not establish a framework for government. The Bill of Rights comprises the first ten amendments to the Constitution, focused primarily on protecting individual liberties rather than outlining government structure. Finally, the Articles of Confederation served as the first governing document of the United States but ultimately proved ineffective and was replaced by the Constitution due to its weaknesses in governing the nation. Thus, the U.S. Constitution is the authoritative document outlining the framework of the U.S. government.
