Dachau, the first Nazi concentration camp, opened in 1933, shortly after Adolf Hitler (1889-1945) became chancellor of Germany. Located in southern Germany, Dachau initially housed political prisoners; however, it eventually evolved into a death camp where countless thousands of Jews died from malnutrition, disease, and overwork or were executed.
In addition to Jews, the camp's prisoners included members of other groups Hitler considered unfit for the new Germany, including artists, intellectuals, the physically and mentally handicapped, and homosexuals. With the advent of World War II (1939-45), some able-bodied Dachau prisoners were used as slave labor to manufacture weapons and other materials for Germany's war efforts. Additionally, some Dachau detainees were subjected to brutal medical experiments by the Nazis. U.S. military forces liberated Dachau in late April 1945.
