The 2nd Division (2. Division) was a unit of the Prussian/German Army. It was formed in Danzig (now Gdańsk, Poland) in March 1816 as a Troop Brigade (Truppen-Brigade). It became the 2nd Division on September 5, 1818. In 1890, the headquarters of the division was relocated to Königsberg (now Kaliningrad, Russia), then the capital of East Prussia. In 1899, the headquarters was moved to Insterburg (now Chernyakhovsk, Russia), further inland and closer to the border with the Russian Empire. From the latter's formation in 1820, the division was subordinated in peacetime to the I Army Corps (I. Armeekorps). The 2nd Division was disbanded in 1919 during the demobilization of the German Army after World War I.
