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. After its opening by Heinrich Himmler, its purpose was enlarged to include forced labor, and, eventually, the imprisonment of Jews, Romani, German and Austrian criminals, and, finally, foreign nationals from countries that Germany occupied or invaded. The 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. The main camp was liberated by U.S. forces on 29 April 1945.
