The 9th Division was a unit of the Prussian/German Army. It was formed in Glogau in November 1816 as a brigade, became the 10th Division on September 5, 1818, and was renumbered the 9th Division on February 28, 1820. The division was subordinated in peacetime to the V 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 Silesia, primarily in Lower Silesia.
German divisions underwent various organizational changes after the Franco-Prussian War. The 9th Division lost all of its original infantry regiments to other divisions and received replacement regiments. The organization of the 9th Division in 1914, shortly before the outbreak of World War I, was as follows:
*5. Niederschlesisches Infanterie-Regiment Nr. 154
9. Kavallerie-Brigade
*Dragoner-Regiment von Bredow Nr. 4
*Ulanen-Regiment Prinz August von Württemberg Nr. 10
9. Feldartillerie-Brigade
*Feldartillerie-Regiment von Podbielski Nr. 5
*2. Niederschlesisches Feldartillerie-Regiment Nr. 41
Order of battle on mobilization
On mobilization in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units. Divisions received engineer companies and other support units from their higher headquarters. The 9th Division was again renamed the 9th Infantry Division. Its initial wartime organization was as follows:
17. Infanterie-Brigade:
*Infanterie-Regiment von Courbière Nr. 19
*3. Posensches Infanterie-Regiment Nr. 58

Late World War I organization
Divisions underwent many changes during the war, with regiments moving from division to division, and some being destroyed and rebuilt. During the war, most divisions became triangular - one infantry brigade with three infantry regiments rather than two infantry brigades of two regiments. An artillery commander replaced the artillery brigade headquarters, the cavalry was further reduced, the engineer contingent was increased, and a divisional signals command was created. The 9th Infantry Division's order of battle on March 11, 1918, was as follows:
18.Infanterie-Brigade:
*Grenadier-Regiment König Wilhelm I Nr. 7
*Infanterie-Regiment von Courbière Nr. 19
*5. Niederschlesisches Infanterie-Regiment Nr. 154
*Maschinengewehr-Scharfschützen-Abteilung Nr. 16
2.Eskadron/Regiment Königs-Jäger zu Pferde Nr. 1
