Other specific themes in her work include androgyny and gender roles, and politics as well. She was in Germany during the Third Reich and had to keep a low profile as her art was labelled as degenerate by the Nazi's, who of course had a famous dislike of new art and instead favored traditional European fine arts.
As I mentioned before, she was a Dada artist; this is an art form that arose after the first world war and came to be because the artists of the time believed that a society that could create such a horrible tragedy as WWI had little to no value. Dada can also be described as anti-art. This art questioned authority and government and was obviously against war, so of course they were not fond of the Nazi party.
