What were concentration camps?

Concentration camps were a system of forced labor camps and detention centers established by the Nazi regime in Germany during World War II. They were used to imprison and systematically murder millions of Jews, as well as other minority groups and political dissidents deemed undesirable by the Nazi government. In these camps, prisoners were subjected to inhumane living conditions, forced labor, and extreme brutality, resulting in the deaths of millions of people through starvation, disease, and mass executions. The most infamous of these camps was Auschwitz, where approximately 1.1 million people were killed.
