On this day in 1942, the Wannsee Conference in Berlin occurred. It was a meeting of 15 high-ranking Nazi government officials who created a plan to implement the Final Solution. This conference was called to organize the roles of each government agency and how they would work together to achieve those evil results.At this time, the Einsatzgruppen (mobile killing units) were already mass murdering Jews in the German-occupied Soviet Union and Serbia, but this meeting was to coordinate the mass murder of 11 million Jews. This 11 million included all Jews in German-occupied lands, as well as the United Kingdom and the neutral countries: Switzerland, Ireland, Sweden, Spain, Portugal, and European Turkey. They planned to bring the Jews who were capable of working to labor camps where they could provide free labor to the Nazis. The Nazis hoped there would be a natural reduction of the Jewish population in having to work all day; the rest of the Jews, including children and the elderly, would be sent to concentration and extermination camps. During the entire meeting the officials spoke in euphemisms, never explicitly saying that they were going to murder Jews. Their intentions were made clear when, a few months later, the first gas chamber was built in Poland and the deportation of Jews to labor and extermination camps began.
