Final answer:
Dachau was the first concentration camp and served as a model for other Nazi concentration camps, where inmates faced forced labor, medical experiments, and mass extermination.
Step-by-step explanation:
Dachau was the first concentration camp, created by Nazi Germany in 1933. It served as a prototype for a network of camps where Jewish people and other minorities were subjected to forced labor, medical experiments, and mass extermination. Despite being a concentration camp, it did not primarily function as an extermination camp such as those like Auschwitz-Birkenau—designed with the express purpose of mass murder. Dachau became the ideal model for other concentration camps; many prisoners there were also forced into medical experiments and faced brutal conditions that often resulted in death due to disease, starvation, or execution.
