American Expeditionary Force

The American Expeditionary Force (AEF) was the U.S. military organization sent to Europe during World War I, primarily between 1917 and 1918. Led by General John J. Pershing, the AEF fought alongside Allied forces against the Central Powers. It played a crucial role in major battles like the Meuse-Argonne Offensive, contributing to the eventual defeat of Germany. The AEF was instrumental in demonstrating America's emerging military power and also laid the groundwork for future U.S. involvement in global conflicts. Its efforts marked a significant shift in the war's dynamics and in American foreign relations.
