Why does it exist?
Historically, the purpose of concentration camps is to "reeducate" through labor those who are resistant to the regime’s totalitarian ideology (political opponents, resistance fighters, etc.). In fact, they are places of repression providing free labor.
And today, what about it?
Several researchers and NGOs consider, for example, that the conditions of internment of hundreds of thousands of Uighurs in Xinjiang (China) present a concentrationary character.
Simply a prison. In a concentration camp, political opponents are usually locked up and have not been given a fair trial. Detainees do not enjoy the common rights of a litigant (principle of adversarial procedure, presumption of innocence, etc.).
An internment camp. In an internment camp are gathered people defined as "undesirable", placed away from the rest of society and put under surveillance.
