German monarchists

Wilhelm, German Crown Prince, Crown Prince of Prussia (Friedrich Wilhelm Victor August Ernst; 6 May 1882 – 20 July 1951) was the eldest child of the last Kaiser, Wilhelm II, German Emperor, and his consort Augusta Victoria of Schleswig-Holstein, and thus a great-grandson of Queen Victoria, and distant cousin to many British Royals, such as Queen Elizabeth II. As Emperor Wilhelm's heir, he was the last Crown Prince of the German Empire and the Kingdom of Prussia, until the abolition of the monarchy.
Wilhelm became crown prince at the age of six in 1888, when his grandfather Frederick III died and his father became emperor. He was crown prince for 30 years until the fall of the empire on 9 November 1918. During World War I, he commanded the 5th Army from 1914 to 1916 and was commander of the Army Group German Crown Prince for the remainder of the war. After his return to Germany in 1923, he fought the Weimar Republic and campaigned for the reintroduction of the monarchy in Germany. After his plans to become president had been blocked by his father, Wilhelm supported Adolf Hitler's rise to power, but when Wilhelm realised that Hitler had no intention of restoring the monarchy, their relationship cooled. Wilhelm became head of the House of Hohenzollern on 4 June 1941 following the death of his father and held the position until his own death on 20 July 1951.

Franz Joseph Hermann Michael Maria von Papen, Erbsälzer zu Werl und Neuwerk (German: [ˈfʁants fɔn ˈpaːpn̩] ; 29 October 1879 – 2 May 1969) was a German conservative politician, reactionary, diplomat, Prussian nobleman and General Staff officer. He served as the chancellor of Germany in 1932, and then as the vice-chancellor under Adolf Hitler from 1933 to 1934.
Born into a wealthy family of Westphalian Catholic aristocrats, Papen served in the Prussian Army from 1898 onward and was trained as a German General Staff officer. He served as military attaché in Mexico and the United States from 1913 to 1915, while also covertly organising acts of sabotage in the United States and quietly backing and financing Mexican forces in the Mexican Revolution on behalf of German military intelligence.
After being expelled as persona non grata by the United States State Department in 1915, he served as a battalion commander on the Western Front of World War I and finished his war service in the Middle Eastern theatre as a lieutenant colonel.
Asked to become chancellor of the Weimar Republic by President Paul von Hindenburg in 1932, Papen ruled by presidential decree. He launched the Preußenschlag coup against the Social Democratic Party-led Government in the Free State of Prussia. His failure to secure a base of support in the Reichstag led to his removal by Hindenburg and replacement by General Kurt von Schleicher.
Determined to return to power, Papen, believing that Adolf Hitler could be controlled once he was in the government, pressured Hindenburg to appoint Hitler as chancellor and Papen as vice-chancellor in 1933 in a cabinet ostensibly not under Nazi Party domination. Seeing military dictatorship as the only alternative to a Nazi Party chancellor, Hindenburg consented. Papen and his allies were quickly marginalized by Hitler and he left the government after the Night of the Long Knives in 1934, during which the Nazis killed some of his allies and confidants. Subsequently, Papen served the German Foreign Office as the ambassador in Vienna from 1934 to 1938 and in Ankara from 1939 to 1944. He joined the Nazi Party in 1938.After the Second World War, Papen was indicted for Nazi war crimes in the Nuremberg trials before the International Military Tribunal but was acquitted of all charges. In 1947, a West German denazification court found Papen to have acted as the main culprit in crimes relating to the Nazi government. Papen was given a sentence of eight years' imprisonment at hard labour, but was released on appeal in 1949. Franz von Papen's memoirs were published in 1952 and 1953; he died in 1969.
