Arthur Seyss-Inquart was an Austrian Nazi. From May 1940 onwards, he was in command of the Netherlands on behalf of Germany. His words carried a lot of weight. In March 1941, he gave a speech to the Dutch section of the NSDAP (the German Nazi party). The speech was held at the Concertgebouw in Amsterdam. It was broadcast on the radio, filmed for a cinema newsreel and the text was also published in a brochure.
A few weeks earlier, the German occupying forces had violently arrested more than 400 Jews. The strikes that followed were also stopped violently. These events were still fresh in the memories of his audience. In his speech, Seyss-Inquart warned the Dutch Jews and their helpers to remember that that would not be the end of it.
