As our nation entered the 20th Century, its new Secretary of War, Elihu Root, was reviewing the nearly disastrous military performance during the just ended War with Spain. He concluded that the War Secretariat was not equipped to effectively direct a unified war effort, and there did not exist a body of officers educated and trained to plan and solve problems from the perspective of the Army as a whole. His conclusions caused him to request and receive permission to establish a War Department staff and an Army War College. In defining the direction for the War College, Secretary Root asked three questions: What shall be taught?; How shall it be taught?; and Who shall be taught? This paper is based on a belief that those three questions are equally valid today, especially considering the dramatic change in world events. The world environment is evolving and with it senior military leadership requirements are taking on an evolution of their own. The Army War College, the ultimate educational institution for tomorrow's senior leaders, must also evolve to meet the needs of a new, different Army. Secretary Root's three questions can provide direction as the Army War College looks to the future. This study is an attempt to answer those questions with a focus on the next century. Conclusions are drawn and recommendations presented in an attempt to link the educational process at the College with the needs of the 21st century Army.
