World War II

Karajan's career continued to thrive at the beginning of the war. In 1939, the Berlin State Opera appointed him State Kapellmeister and conductor of concerts by the Prussian State Orchestra. He then became music director of the Staatskapelle Berlin, with which he toured Rome with extraordinary success. The next year, his contract in Aachen was discontinued. His marriage to Anita Gütermann (with one Jewish grandparent) and the prosecution of his agent Rudolf Vedder also contributed to his temporary professional decline, leaving him few engagements beyond a limited season of concerts with the Staatskapelle.

By 1944, Karajan was, by his account, losing favour with the Nazi leadership, but he conducted concerts in Berlin as late as 18 February 1945. A short time later, in the closing stages of the war, he and his wife fled Germany for Milan, relocating with the assistance of Victor de Sabata.

Karajan's increased prominence from 1933 to 1945 has led to speculation that he joined the Nazi Party solely to advance his career. Critics such as Jim Svejda have pointed out that other prominent conductors, such as Arturo Toscanini, Otto Klemperer, Erich Kleiber, and Fritz Busch, fled Germany or Italy at the time. Richard Osborne noted that among the many significant conductors who continued to work in Germany during the war years— Wilhelm Furtwängler, Carl Schuricht, Karl Böhm, Hans Knappertsbusch, Clemens Krauss and Karl Elmendorff —Karajan was one of the youngest and thus one of the least advanced in his career. He was allowed to conduct various orchestras and was free to travel, even to the Netherlands to conduct the Concertgebouw Orchestra and make recordings there in 1943. He conducted for an audience of 300 Nazi armaments officials at a conference convened by Albert Speer in Linz, Austria, on 24–25 June 1944. In September 1944, he was listed on the Gottbegnadeten list (God-gifted list of artists exempt from mobilisation).

Karajan's denazification tribunal, held in Vienna on 15 March 1946, cleared him of illegal activity during the Nazi period. The Austrian denazification examining board discharged Karajan on 18 March 1946, and he resumed conducting shortly thereafter. Years later, former West German Chancellor Helmut Schmidt said of Karajan's Nazi party membership card, "Karajan was obviously not a Nazi. He was a Mitläufer."
