The Imperial German Army (Deutsches Heer) was the name given to the combined land and air forces — not including the Marine-Fliegerabteilung maritime aviation formations of the Kaiserliche Marine — of the German Empire. The term Deutsches Heer is also used for the modern German Army, the land component of the Bundeswehr. The German Army was formed after the unification of Germany under Prussian leadership in 1871, and dissolved in 1919, after the defeat of the German Empire in World War I.
