The 31st Division (31. Division) was a unit of the Prussian/GermanArmy.[1] It was formed on March 20, 1871, and was headquartered in Straßburg (now Strasbourg, France) until 1912, and then in Saarbrücken.[2] The division was subordinated in peacetime to the XV Army Corps (XV. Armeekorps) until 1912, and then to the XXI Army Corps (XXI. Armeekorps).[3] The division was disbanded in 1919 during the demobilization of the German Army after World War I. The division was recruited primarily in the southern part of the Rhine Province, but during World War I also drew replacements from Westphalia.

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in August 1914 at the beginning of World War I, most divisional cavalry, including brigade headquarters, was withdrawn to form cavalry divisions or split up among divisions as reconnaissance units.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 31st Division was redesignated the 31st Infantry Division. Its initial wartime organization was as follows:[7]
32. Infanterie-Brigade
8. Rheinisches Infanterie-Regiment Nr. 70
10. Lothringisches Infanterie-Regiment Nr. 174

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 (a "square division"). 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 31st Infantry Division's order of battle on January 1, 1918, was as follows:[8]
32. Infanterie-Brigade
8. Rheinisches Infanterie-Regiment Nr. 70
Infanterie-Regiment Hessen-Homburg Nr. 166
10. Lothringisches Infanterie-Regiment Nr. 174
5.Eskadron/Ulanen-Regiment Großherzog Friedrich von Baden (Rheinisches) Nr. 7
Artillerie-Kommandeur 31:
1. Unter-Elsässisches Feldartillerie-Regiment Nr. 31
Fußartillerie-Bataillon Nr. 44 (from June 22, 1918)
Stab Pionier-Bataillon Nr. 93:

Notes
^From the late 1800s, the Prussian Army was effectively the German Army, as during the period of German unification (1866-1871) the states of the German Empire entered into conventions with Prussia regarding their armies and only the Bavarian Army remained fully autonomous.
