Albrecht_von_Roon--Franz_Von_Papen

Albrecht Theodor Emil Graf von Roon (German pronunciation: [ˈʔalbʁɛçt fɔn ʁoːn]; 30 April 1803 – 23 February 1879) was a Prussian soldier and statesman. As Minister of War from 1859 to 1873, Roon, along with Otto von Bismarck and Helmuth von Moltke, was a dominating figure in Prussia's government during the key decade of the 1860s, when a series of successful wars against Denmark, Austria, and France led to German unification under Prussia's leadership. A moderate conservative and supporter of executive monarchy, he was an avid modernizer who worked to improve the efficiency of the army.
