Question: The man that made August von Mackensen a Prussian state councillor in 1933 was the last commander of what fighter wing once led by Manfred von Richthofen?
Context: The Army Group Mackensen (German: "Heeresgruppe Mackensen, HGr.  Mackensen" ) which operated in Poland between 22 April 1915 and 8 September 1915 during World War I under the command of Field Marshal August von Mackensen , was an army group of the Imperial German Army. The "Mackensen" class was the last class of battlecruisers to be built by Germany in World War I.  The design initially called for seven ships, but three of them were redesigned as the "Ersatz Yorck" class .  Of the four ships of the "Mackensen" class, "Mackensen", "Graf Spee", and "Prinz Eitel Friedrich" were launched, and "Fürst Bismarck" was not—but none were completed, after wartime shipbuilding priorities were redirected towards U-boat—and the ships were broken up in the early 1920s.  The lead ship of the class was named for August von Mackensen, a prominent military commander during the war.  In response to the "Mackensen"-class ships, the British Royal Navy laid down the Admiral-class battlecruiser s, all but one of which would eventually be cancelled; the sole survivor, HMS "Hood" , was completed after the end of the war. Manfred von Richthofen (4 February 1934 – 1 May 2014) was a German hockey player and coach.  He was also an honorary President of German's national Olympic federation.  He was the nephew of World War I German pilot Manfred von Richthofen (the "Red Baron").  His career began during the 1950s.  He retired in 2006.  Richthofen was born in Berlin, Germany. Lothar Freiherr von Richthofen (born Lothar Siegfried Freiherr von Richthofen; 27 September 1894 – 4 July 1922) was a German First World War fighter ace credited with 40 victories.  He was a younger brother of top-scoring ace Manfred von Richthofen (the "Red Baron") and a distant cousin of Luftwaffe Field Marshal Wolfram von Richthofen. Ferdinand Freiherr von Richthofen (5 May 18336 October 1905), better known in English as Baron von Richthofen, was a German traveller, geographer, and scientist.  He is noted for coining the terms "Seidenstraße" and "Seidenstraßen" = "Silk Road(s)" or "Silk Route(s)" in 1877.  He also standardized the practices of chorography and chorology.  He was an uncle of the World War I flying ace Manfred von Richthofen, best known as the "Red Baron". "Jagdgeschwader" 1 (JG 1) of World War I, was a fighter wing of the German Luftstreitkräfte, comprising four "Jastas" (fighter squadrons).  The first unit of its type formed under that classification, JG I was formed on 24 June 1917, with Manfred von Richthofen as commanding officer, by combining "Jastas" 4, 6, 10 and 11.  JG 1 became known as "The Flying Circus" or "Richthofen's Circus" because of the bright colours of its aircraft, and perhaps also because of the way the unit was transferred from one area of Allied air activity to another - moving like a travelling circus in trains, and frequently setting up in tents on improvised airfields. Anton Ludwig August von Mackensen (6 December 1849 – 8 November 1945), born August Mackensen, was a German field marshal.  He commanded with extreme success during the First World War and became one of the German Empire's most prominent and competent 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.  During the Nazi era, Mackensen remained a committed monarchist and sometimes appeared at official functions in his First World War uniform.  He was suspected of disloyalty to the Third Reich, although nothing was proven against him. Hermann Wilhelm Göring (or Goering; ] ; 12 January 1893 – 15 October 1946) was a German political and military leader as well as one of the most powerful figures in the Nazi Party (NSDAP) that ruled Germany from 1933 to 1945.  A veteran World War I fighter pilot ace, he was a recipient of the "Pour le Mérite".  He was the last commander of "Jagdgeschwader" 1, the fighter wing once led by Manfred von Richthofen. Karl Ernst Manfred Freiherr von Richthofen (24 May 1855 – 28 November 1939) was a German "General der Kavallerie" (General of the Cavalry) during World War I and recipient of the order Pour le Mérite, known informally as the Blue Max.  Richthofen was a great uncle of his more famous namesake Manfred von Richthofen, known as the Red Baron, who was his godson and named after him. Bolko von Richthofen (September 13, 1899 – March 18, 1983) was a German archaeologist and a distant relative of the family of Manfred von Richthofen, the "Red Baron".  He is sometimes confused with his distant cousin and namesake, Karl Bolko von Richthofen (1903–1971) – the youngest brother of the fighter ace.
