Conspiracy — Germany
January 20 1942 — fifteen senior Nazi officials meet at this lakeside villa for 90 minutes to coordinate the extermination of European Jewry.
The Wannsee Conference did not order the Holocaust — that was already underway. It coordinated logistics: which agencies were responsible for which populations, what to do with mixed-heritage individuals, and how to manage the bureaucracy of continental murder. The villa is now the House of the Wannsee Conference memorial.
