How did the Department of War change in terms of its name and organization?Write a full paragraph that summarizes what you learned in this assignment.

Answer:

The Department of War was established in 1789 to manage the United States military and transition from state militias to an official army. In 1947, following the National Security Act, this cabinet division was reorganized and renamed the Department of Defense to oversee the nation's military actions more comprehensively. Later, in 2002, the Department of Homeland Security was created as a separate entity to focus on safety and security within the nation's borders.
