On what date was the first Sergeant Major of the Marine Corps appointed?

The appointment of the first Sergeant Major of the Marine Corps is historically significant as it marked a formal recognition of the role of senior enlisted leadership within the Marine Corps. The title was established to provide a seasoned enlisted leader to advise the commanding officer on matters pertaining to enlisted Marines, serving to enhance the professionalism and effectiveness of the force.

The correct choice reflects the date when this pivotal role was created, linking it to a time when the Corps was experiencing expansion and the need for structured leadership at all levels. It's essential to understand that this position was not presented until 1923, but the rank and role directly became recognized following developments in military structure leading up to that time.

In contrast, other dates mentioned do not correspond with the established historical context for the formation of the Sergeant Major position. Specific events in Marine Corps history, such as the establishment of the Corps or changes in its organizational structure, are reflected in those dates but do not relate to the appointment of the first Sergeant Major.
