Armee-Korps) was a corps level command of the Prussian and then the Imperial German Armies from the 19th Century to World War I. VI AK originated in 1815 as the General Command for the Province of Silesia, with headquarters in Breslau.

During the Franco-Prussian War, the Corps was initially held back in Silesia against the possibility of intervention by Austria-Hungary.

The 25 peacetime Corps of the German Army (Guards, I - XXI, I - III Bavarian) had a reasonably standardised organisation.

Divisions received engineer companies and other support units from the Corps headquarters.

On mobilisation, VI Corps was assigned to the 4th Army forming part of centre of the forces for the Schlieffen Plan offensive in August 1914 on the Western Front.
