Abstract
This chapter shows that taboos erected around crimes inhibit individuals and nations' work of mourning for the victims of crimes. The work of mourning is the precondition that individuals and nations take responsibility for past crimes, show solidarity with the victims and their descendants, and make sure that such crimes are not repeated. I bring Theodor W. Adorno and Sigmund Freud in conversation to explain the connection between taboos and the failure to mourn. I further detail this connection with Antigone as an example of taboo and denied mourning. I also explain that the taboos erected around the National Socialist genocide on Roma and Sinti ("gypsies") do not allow Austrians to mourn the loss of this population. As a result, their taking responsibility for this crime remains stifled, and they fail to show solidarity with the Roma and Sinti genocide victims.
