Dachau was a Nazi concentration camp opened on 22 March 1933, which was initially intended to hold political prisoners. It is located on the grounds of an abandoned munitions factory northeast of the medieval town of Dachau, about 16 km (10 mi) northwest of Munich in the state of Bavaria, in southern Germany.

Dachau served as a prototype and model for the other German concentration camps that followed. Almost every community in Germany had members taken away to these camps.

Dachau camp system grew to include nearly 100 sub-camps, which were mostly work camps or Arbeitskommandos, and were located throughout southern Germany and Austria.
