The noun phrase designates the United States Armed Forces sent to Europe during World War I. Under the command of General John J. Pershing, this entity comprised soldiers, Marines, and support personnel. An example of its function is observed in its deployment to France to combat the German Empire, marking a significant shift in American foreign policy.
The emergence of this military body was vital because it represented America’s commitment to Allied victory and significantly altered the balance of power on the Western Front. Its presence provided crucial manpower and resources, bolstering the morale and capabilities of the Allied forces, ultimately contributing to the defeat of the Central Powers. The historical context surrounding its creation involves the debate over interventionism versus isolationism, a prominent issue in American politics at the time.
