The brutality of World War 1, the mud, mutilations and futility, haunted Dix’s work. His art revealed the decadence and despair of the Weimar years. He was declared a degenerate artist by the Nazis and stripped of his position as a professor at the Dresden art school. He was even accused of plotting to kill Hitler in 1936 but later released (Duggan).
