The 7th Division was a unit of the Prussian/German Army. It was formed in Magdeburg in November 1816 as a brigade and became a division on September 5, 1818. The division was subordinated in peacetime to the IV Army Corps. The division was disbanded in 1919 during the demobilization of the German Army after World War I. The division was recruited primarily in the Province of Saxony, also known as Prussian Saxony.
German divisions underwent various organizational changes after the Franco-Prussian War. The 7th Division exchanged its regiment from the Duchy of Anhalt for the Hanoverian 165th Infantry Regiment, broadening its recruiting area The organization of the division in 1914, shortly before the outbreak of World War I, was as follows:
13. Infanterie Brigade
* Infanterie-Regiment Fürst Leopold von Anhalt-Dessau Nr. 26
* Feldartillerie-Regiment Prinz-Regent Luitpold von Bayern Nr. 4
* Altmärkisches Feldartillerie-Regiment Nr. 40
