The German Duden lexicon defines Vergangenheitsbewältigung as "public debate within a country on a problematic period of its recent history—in Germany on National Socialism, in particular"[3][4]—where "problematic" refers to traumatic events that raise sensitive questions of collective culpability. In Germany, and originally, the term refers to embarrassment about and often remorse for Germans' complicity in the war crimes of the Wehrmacht, Holocaust, and related events of the early and mid-20th century, including World War II. In this sense, the word can refer to the psychological process of denazification.
