What document outlined the rights and responsibilities of U.S. citizens?

The U.S. Constitution is the foundational document that outlines the rights and responsibilities of U.S. citizens. It establishes the framework for the federal government and enumerates the powers granted to different branches of government. The Constitution also includes provisions that protect individual rights through various amendments.

While the Bill of Rights, which comprises the first ten amendments to the Constitution, specifically enumerates certain individual rights and freedoms, the Constitution as a whole is the document that defines citizenship and lays down the broader legal framework governing all citizens, including their responsibilities, such as obeying laws and serving on juries. The other documents mentioned—like the Declaration of Independence and the Articles of Confederation—do not serve the same purpose in defining the rights and responsibilities of citizens in the structured way that the Constitution does.
