Ministry of War (Prussia)
The Prussian War Ministry was gradually established between 1808 and 1809 as part of a series of reforms initiated by the Military Reorganization Commission created after the disastrous Treaties of Tilsit. The War Ministry was to help bring the Army under constitutional review, and, along with the General Staff systematize the conduct of warfare. Gerhard von Scharnhorst, the most prominent and influential of the reformers, served as acting war minister from roughly 1808 until 1810 (he was also Chief of the General Staff). History. The War Ministry was established on 25 December 1808, replacing the old  military institutions. The Ministry consisted of two departments. The first department was responsible for the command and condition of the army, the second for its financial administration. At first, no War Minister was appointed due to the resistance of Frederick William III. Gerhard von Scharnhorst became head of the first department (the General War Department; "Allgemeines Kriegsdepartement") and Lieutenant Colonel Graf Lottum became head of the second department. Scharnhorst also functioned as acting War Minister, as long as no permanent appointment was made. The first department in turn consisted of three divisions. The first division represented the continuation of the  old Adjutancy-General and was also known as the "secret military cabinet". It in turn had control over the general war chancellery. The second division of the War Ministry dealt with general army matters: troop formations, replacements and turnover, housing, military exercises, and mobilization. A third division was also created: the artillery and engineering division. This in turn comprised the artillery section, which dealt with artillery equipment, rifle production, ordnance production, gunpowder factories, etc.; and the engineering section, which was responsible for maintaining the fortresses. The second department, the military economy department, had four divisions. The first division was responsible  for pay, the second for catering, the third clothing and the fourth invalids. In 1919, it formed the basis of Weimar Germany's Ministry of the Reichswehr. Location.
