The last years of Musil's life were dominated by Nazism and World War II: the Nazis banned his books. He saw early Nazism first-hand while he was living in Berlin from 1931 to 1933. In 1938, when Austria was annexed by Nazi Germany, Musil and his Jewish wife, Martha, left for exile in Switzerland, where he died at the age of 61. Martha wrote to Franz Theodor Csokor that he had suffered a stroke.
