With the seizure of power of the National Socialists in 1933 began an active period of persecution for political dissidents and Jewish fellow citizens in Germany. By November 1938 all Jewish residents of the town had been forcibly removed. Open political resistance during the war years was limited; the town priest, Josef Stelze, was placed briefly in custody, Rupert Berger, Bavarian People's Party representative and the first post-war elected Mayor of Traunstein, was for a period incarcerated in the Dachau concentration camp. In 1939 Traunstein had an estimated population of 11,500. By the end of the war 523 of that number were registered as killed as a direct result of the conflict, a further 73 registered as missing.
