The Imperial German Army was replaced after World War I with the volunteer "Reichswehr" of the Weimar Republic. Although the Treaty of Versailles attempted to disarm Germany, the "Reichswehr" discreetly maintained many of the traditions of the Prussian Army. The General Staff was camouflaged as a non-descript "Truppenamt" (troop office), while the War Academy was replaced with decentralized divisional schools. Hans von Seeckt, the head of the "Reichswehr", designated the new military's battalions as successors of the traditions of Prussian regiments.
