The corps was originally formed on 15 December 1940 in Germany. At the dawn of Operation Barbarossa, on 22 June 1941, it was redesignated as the XXXXVIII Panzer Corps. The Corps was attached to Field Marshal Ewald von Kleist's Panzer Group 1, a part of Army Group South. The corps took part in the Battle of Brody early in the campaign, and later saw action at Berdichev and Kirovograd. As did all German Corps on the Eastern Front, the XXXXVIII Corps implemented the criminal Commissar Order.
