What historical event led to the origin of Marine Corps' Mess Nights?

The origin of Marine Corps' Mess Nights can be traced back to the Fourth Marine Regiment in Shanghai, China, during the 1920s. This event is significant as it marked the establishment of a tradition in which Marines would gather for formal dining and camaraderie within their units. Mess Nights serve as an opportunity for the members of the Marine Corps to bond, share stories, and uphold traditions in a more relaxed yet respectful environment. This social structure is rooted in the discipline and camaraderie that are crucial aspects of Marine culture.

While World War I, the formation of the United States Navy, and the Battle of Iwo Jima are important events in military history, they do not specifically relate to the development of the Mess Night tradition. Instead, it was the unique experiences and circumstances of the Fourth Marine Regiment during its time in Shanghai that laid the groundwork for these gatherings within the Marine Corps.
