Which document outlines the rights of citizens in the United States?

The Constitution is the foundational document that outlines the framework of the U.S. government and establishes the rights of citizens. It sets forth the structure of government, including the separation of powers among the legislative, executive, and judicial branches, and articulates the relationships between the federal government and the states.

While the Constitution itself does enumerate some rights and principles, the Bill of Rights, which comprises the first ten amendments to the Constitution, specifically details individual rights and protections afforded to citizens. These amendments guarantee essential freedoms such as the right to free speech, assembly, and religion, as well as protections against unreasonable searches and seizures.

The Declaration of Independence, although a critical historical document that articulates the philosophical foundation of American liberty, does not serve to outline specific rights of citizens; rather, it asserts the colonies' intention to separate from British rule. The Articles of Confederation, the first governing document of the United States, was ultimately ineffective in outlining the rights of citizens or establishing a strong central government.

Overall, the Constitution serves as the primary legal document that establishes and protects the rights of citizens in the United States.
