IV Corps (German Empire)

The IV Army Corps / IV AK (German: IV. Armee-Korps) was a corps level command of the Prussian and then the Imperial German Armies from the 19th Century to World War I.

It was established on 3 October 1815 as the General Command in the Duchy of Saxony (Generalkommando im Herzogtum Sachsen) and became the IV Army Corps on August 30, 1818. Its headquarters was in Magdeburg and its catchment area included the Prussian Province of Saxony and the adjacent Saxon Duchies (Saxe-Altenburg, Anhalt) and Principalities (Schwarzburg-Sondershausen, Schwarzburg-Rudolstadt, Reuss Elder Line and Reuss Junior Line).

In peacetime, the Corps was assigned to the VI Army Inspectorate but joined the 1st Army at the start of the First World War. It was still in existence at the end of the war in the 6th Army, Heeresgruppe Kronprinz Rupprecht on the Western Front. The Corps was disbanded with the demobilisation of the German Army after World War I.
