On March 15, 1919, 100 years ago today, the American Legion formed (Paris). From the article:
"The Paris Caucus (March 15–17, 1919)
Having immediately received a blizzard of acceptances to attend the opening of the "Liberty League Caucus", as he had begun to refer to it, Temporary Secretary Eric Fisher Wood began to search for use of a room of sufficient size to contain the gathering. The Cirque de Paris had been retained, a large, multisided amphitheater sufficient to accommodate a crowd of about 2,000. Delegates began to assemble from all over France. The 10:00 am scheduled start was delayed due to various logistical problems, with a beginning finally made shortly after 2:45 pm.
As "Temporary Chairman" Teddy Roosevelt, Jr. had already departed for America, the session was gaveled to order by Eric Wood, who briefly recounted Roosevelt's idea and the story of the 20 AEF officers who had jointly helped to give the new organization form. In his keynote opening remarks Wood recommended to the delegates of the so-called Paris Caucus that they do three things: first, set up an apparatus to conduct a formal founding conference in the United States sometime in the winter; second, the body should draft a tentative name for the organization; and finally, the body should compose a provisional constitution to be submitted to the founding convention for its acceptance or rejection.
William G. Price Jr. was selected to preside. Convention rules were decided upon and four 15-member committees were chosen. The Committee on Name reported back that they had considered a dozen potential names, including Veterans of the Great War, Liberty League, American Comrades of the Great War, Legion of the Great War, and The American Legion, among others. This list was whittled down to five ranked choices for the consideration of the Caucus, with "The American Legion" the preferred option. It was noted in passing during the course of debate on the topic that Teddy Roosevelt, Jr. had been responsible for an earlier organization called "The American Legion" in 1914, a "preparedness" society with a claimed membership of 35,000 which had been absorbed into the Council of National Defense in 1916.
The Committee on Constitution reported with a report containing the draft of a Preamble for the organization, specifying organizational objectives. This document stated that the group
... desiring to perpetuate the principles of Justice, Freedom, and Democracy for which we have fought, to inculcate the duty and obligation of the citizen to the State; to preserve the history and incidents of our participation in the war; and to cement the ties of comradeship formed in service, do propose to found and establish an Association for the furtherance of the foregoing purposes.
The majority report of the Committee on Convention recommended that 11 am on November 11, 1919—one year to the hour after the termination of hostilities in World War I—be selected as the date and time for the convocation of a national convention. No location was specified.
The Committee on Permanent Organization recommended an organization based upon territorial units rather than those based upon military organizations, governed by an Executive Committee of 50, with half of these coming from the officer corps and the other half coming from the ranks of enlisted men."
