The 4th Landwehr Division (4. Landwehr-Division) was an infantry division of the Imperial German Army during World War I. It was formed on mobilization of the German Army in August 1914 under the "Higher Landwehr Commander 4" (Höherer Landwehr-Kommandeur 4). The Landwehr was the third category of the German Army, after the regular Army and the reserves. Thus Landwehr divisions were made up of older soldiers who had passed from the reserves, and were intended primarily for occupation and security duties rather than heavy combat. The division was primarily raised in the Prussian provinces of Upper and Lower Silesia. It was disbanded in 1919 during the demobilization of the German Army after World War I.
