The War Powers Act was a law passed by Congress because it would limit the power of the executive branch.
This act was passed after the Vietnam War, in which Congress gave the president almost unlimited power to put troops wherever he saw fit. This was part of the Golf of Tonkin Resolution. This did not end well, as the US involvement in Vietnam was a failure.
