"Staatsbürgerliche Vorträge" was banned by the Nazis in 1933, the same year in which Hundhammer along with fellow Bavarian People's Party (BVP) members were arrested by the Bavarian Political Police (later: Gestapo). After being arrested on 21 June 1933, Hundhammer was placed in the newly opened Dachau concentration camp on 29 June. He was released on 22 July of the same year.
