Which 1942 Nazi operation deported Jews from Germany and occupied Europe to ghettos and killing centers?

The 1942 Nazi operation deporting Jews from occupied Europe to ghettos and killing centers was Operation Reinhard.

Operation Reinhard was the code name for the German plan to murder the Jewish population of the General Government, the German-occupied part of Poland. It began in 1942 and was named after Reinhard Heydrich, who had been assassinated in Prague in May that year. The operation was directed by Odilo Globocnik under the authority of Heinrich Himmler.

The principal killing centers associated with the operation were Bełżec, Sobibór, and Treblinka. Victims were transported from ghettos and other occupied territories, often by train, and murdered shortly after arrival. The operation also involved the plunder of victims’ property and the dismantling of evidence.

Historians generally estimate that about 1.5 million Jews were murdered during Operation Reinhard, making it one of the central phases of the Holocaust. It should not be confused with Operation Barbarossa, the 1941 German invasion of the Soviet Union.
