A tragic event that occurred at the concentration camps during World War II was the mass extermination of millions of people, primarily Jews, in what is known as the Holocaust. Nazi Germany established concentration and extermination camps, where individuals were subjected to horrific conditions, forced labor, and systematic killing. Approximately six million Jews, along with millions of others, including Romani people, disabled individuals, and political dissidents, were murdered. The Holocaust remains one of history's most significant and devastating atrocities, serving as a stark reminder of the consequences of hatred, discrimination, and totalitarianism.
