The Dachau Concentration Camp was opened by Adolf Hitler's Nazi government in 1933, and served as a model for later concentration camps. Today, the camp is a memorial to the more than 32,000 people who died and the more than 200,000 who were imprisoned there during the Nazi regime. The memorial was established as a site of memory and education in 1965, 20 years after Dachau was liberated by American troops.
