Congress, the President, and the War Powers (Fundamental Principles of Government)

This lesson will explore the implementation of the war-making power from the first declared war under the Constitution—the War of 1812—to the Iraq War. Using primary sources, students will investigate how the constitutional powers to initiate war have been exercised by the legislative and executive branches at several key moments in American history. They will also evaluate why and how the balance of authority in initiating war has changed over time, and the current balance of power.
