Formed at the outbreak of World War I, 7th Army formed the extreme left (southern) wing of the German Armies on the Western Front. During the execution of the French Plan XVII, the 7th Army covered Alsace, successfully repulsing the French attack in the Battle of Lorraine. It then took part in the Race to the Sea, an attempt by both German and Anglo-French armies to turn each other's flank.

At the end of the war it was serving as part of Heeresgruppe Deutscher Kronprinz.^[3]

The 7th Army had the following commanders during its existence.^[5]

• Armee-Abteilung or Army Detachment in the sense of "something detached from an Army". It is not under the command of an Army so is in itself a small army.^[7]
• Armee-Gruppe or Army Group in the sense of a group within an Army and under its command, generally formed as a temporary measure for a specific task.
• Heeresgruppe or Army Group in the sense of a number of armies under one commander.
