One of the first Nazi Concentration Camps, located in the small town of Dachau, about ten miles (15 km) northwest of Munich.
The first group of so-called protective-custody prisoners, consisting mainly of Communists and Social Democrats, was brought to Dachau on March 22, 1933. On becoming commandant of the camp in June 1933, Theodor Eicke setup a scheme of organiztion with detailed regulations for camp life. Later, when Eicke was appointed inspector general for all concentration camps, these regulations were used, with local variations, elsewhere. With Dachau as his model, he developed an institution that was intended, by its very existence, to spread fear among the populace, and be an effective tool for silencing every opponent of the regime. Dachau became a useful training ground for the SS. The transformation of the terror system of National Socialism into bloody reality began in the Dachau concentration camp.
I bolded the date because I thought it was strange that Dachau was founded when Hitler was still only Chancellor. Hindenberg was still alive, Hitler was only second fiddle. I didn't know Hitler had the power to do this at that time. And didn't Hindenberg have any say in the matter? Couldn't he have protested because he was, after all, the President?
