What article of the Constitution establishes the executive branch?

The second article of the Constitution specifically establishes the executive branch of the federal government. It outlines the structure, powers, and responsibilities of the President of the United States, along with the Vice President and the Cabinet. The article begins by stating that the executive power is vested in a President, who must be a natural-born citizen and at least 35 years old. This foundational framework sets the stage for how the executive branch operates, including the President's role in enforcing laws, conducting foreign policy, and serving as the Commander in Chief of the armed forces.

In contrast, the first article of the Constitution establishes the legislative branch, detailing the roles and powers of Congress. The third article delineates the judicial branch and the system of federal courts. The fourth article deals with the states' powers and their interactions with the federal government. Thus, the correct answer, focusing solely on the executive branch, is found in Article II.
