In 1931, he joined the
SS and 1932 in the
NSDAP. That same year, he became one of the founders of the
Bund nationalsozialistischer Bühnen- und Filmkünstler ("Union of National Socialist Stage and Movie Artists"), which was renamed
Kameradschaft der Deutschen Künstler ("Fellowship of German Artists") after
Hitler's rise to power in 1933. After some personal assignments for Adolf Hitler in 1936, Arent was appointed
Reichsbühnenbildner ("Reich Stage Designer"), a title intended primarily to underscore Arent's exemplary position as a set designer and outfitter. Occasionally, Hitler imposed his own stage designs in a kind of teacher-student relationship, a relationship that would greatly benefit Arent's career. Hitler described him as one of the greatest stage designers. Arent, whose artistic views were shared and probably influenced by Hitler, favored a realistic, often monumental style in his own sets and costumes. Nevertheless, he was ultimately unable to develop his own style, partly due to the outbreak of
World War II, and because of competition in his field of expertise. His task as a designer of street decorations during major marches also had an effect on his stage style. He was also the designer of the diplomatic uniforms for the Foreign Ministry. On 20 April 1937, he received the title of professor, like many other leading Nazi culture officials. In addition to his party responsibilities, Arent continued to work as an architect. His most famous work was the design of the Berlin House of the
German Labour Front (DAF). In the spring of 1939, Arent was appointed "Reich Commissioner for Fashion", an office that was soon terminated due to the war. == Wartime years and death ==
