Which article of the Constitution outlines the legislative branch?

The legislative branch of the United States government is established and described in Article I of the Constitution. This article outlines the structure, powers, and responsibilities of Congress, which is divided into two chambers: the Senate and the House of Representatives. Article I details the processes for making laws, the specific powers granted to Congress, and the limits on those powers. It emphasizes the role of the legislature as a representative body that reflects the will of the people, making it a cornerstone of the democratic process in the U.S.

In contrast, Article II focuses on the executive branch, outlining the powers and responsibilities of the President, while Article III establishes the judicial branch, detailing the structure and powers of the federal court system. Article IV pertains to the states and their interactions with one another and with the federal government. Thus, Article I is the definitive and necessary reference for understanding the legislative branch of the U.S. government.
