Which branch declares war?

• A. Legislative
• B. Executive
• C. Judicial
• D. None

Answer: (A)

The main idea is who has the formal authority to declare war. Under the Constitution, that power belongs to the legislative branch, specifically Congress. This setup gives Congress the ability to officially declare war and to raise and fund the armed forces, creating a check on the President’s role as Commander in Chief who leads military action but cannot unilaterally declare war. In practice, presidents can deploy forces or seek authorization and treaties, but the formal act of declaring war is a congressional power. Historically, wars have been formally declared by Congress in some cases, while many modern conflicts have been authorized through other congressional steps or executive actions. So the branch that declares war is the legislative branch.
