text: Between 1933 and 1945, the Nazis glorified Frederick as a precursor to Adolf Hitler. In an attempt to legitimise the Nazi regime, Propaganda Minister Joseph Goebbels commissioned artists to render fanciful images of Frederick, Bismarck, and Hitler together to create a sense of a historical continuum amongst them. Throughout World War II, Hitler often compared himself to Frederick, and he kept a copy of Anton Graff's portrait of Frederick with him to the end in the Führerbunker in Berlin.
  After the war, the role of Prussia in German history was minimised and Frederick's reputation was downgraded in both East and West Germany, partly due to the Nazis' fascination with him and his connection with Prussian militarism. During the second half of the 20th century, political attitudes towards Frederick's image were ambivalent, particularly in communist East Germany. For example, immediately after World War II images of Prussia were removed from public spaces, including Frederick's equestrian statue on the Unter den Linden, but in 1980 his statue was re-erected. Since the end of the Cold War, Frederick's reputation has continued to grow in reunified Germany.
  In the 21st century, the view of Frederick as a capable and effective leader remains strong among military historians. However, the originality of his achievements is debated, as many were based on developments already underway. He has been studied as a model of servant leadership in management research and is held in high regard for his patronage of the arts. He has been seen as an exemplar of enlightened absolutism, though this label has been questioned in the 21st century as many enlightenment principles directly contrast with his military reputation.
