1st Division (Reichswehr)

The 1st Division was a unit of the Reichswehr, the armed forces of Germany during the Weimar Republic.

Creation
In the Order of 31 July 1920 for the Reduction of the Army (to comply with the upper limits on the size of the military contained in the Treaty of Versailles), it was determined that in every Wehrkreis (military district) a division would be established by 1 October 1920. The 1st Division was formed in January 1921 out of the Reichswehr's 1st and 20th Brigades, both part of the former Übergangsheer (Transition Army).

It consisted of 3 infantry regiments, the 1st, 2nd, and 3rd (Prussian) Infantry Regiments. It also included the 1st (Prussian) Artillery Regiment, an engineering battalion, a signals battalion, a transportation battalion, and a medical battalion. It was subordinated to Gruppenkommando 1.

The commander of Wehrkreis I was simultaneously the commander of the 1st Division. For the leadership of the troops, an Infanterieführer and an Artillerieführer were appointed, both subordinated to the commander of the division.

The unit ceased to exist as such after October 1934, and its subordinate units were transferred to the 11 new divisions created in that year. The 1st (Prussian) Infantry Regiment provided the personnel for the infantry regiments of the 1st Infantry Division of the newly created Wehrmacht.
