Answer:
Operation Reinhard involved the creation of the three extermination camps at Belzec, Sobibor, and Treblinka.
Explanation:
The Holocaust was one of the most heinous crimes of genocide ever done in the history of the world. This mass extermination of the Jewish people during the German Nazi regime would become a blot in the minds of millions of people and change the course of history too.
With the intention of keeping the Jews in a separate place, the Nazis under Hitler constructed numerous concentration camps. These camps not only act as shelters for "Jews" and making them work, but they also became the killing ground for those 'invalid' or no longer useful. The camps have killing chambers where people were poisoned by gas and thus, enables mass killings and removal of 'deadweight'. This plan to kill Jewish people was given the codename "Operation Reinhard", creating three killing centers namely Belzec, Sobibor, and Treblinka.
