Anton Ludwig August von Mackensen (6 December 1849 – 8 November 1945), born August Mackensen, was a German soldier and field marshal. He commanded with success during the First World War and became one of the German Empire’s most prominent military leaders. After the Armistice, Mackensen was interned for a year. He retired from the army in 1920 and was made a Prussian state councillor in 1933 by Hermann Göring. Mackensen, a nationalist rather than a National Socialist, frequently appeared at Nazi functions wearing his imperial cavalry uniform and became a major symbol of the integration of the Second and Third Reich.
