This division was named rather than numbered, as were the Philippine, Panama Canal Division and Americal Divisions. It was first activated under the peacetime Square Division Table of Organization and Equipment (TO&E) on 25 February 1921 as the Hawaiian Division using assets of the World War I era 11th Infantry Division. It, the Philippine Division, and the Americal Division were the last three U.S. Army divisions to be named rather than numbered. The division retained this TO&E until 1941, when it was reorganized under a triangular division TO&E, and part of its former organization became the core of the new 24th Infantry Division and 25th Infantry Division.
