What significant meeting took place at the Wannsee Conference in January 1942?

The Wannsee Conference, held on January 20, 1942, was crucial in the formulation of the Holocaust, specifically focusing on the systematic extermination of the Jewish population in Europe, commonly referred to as the 'final solution.' This meeting involved high-ranking Nazi officials who coordinated the logistics for the mass deportation and extermination of Jews to concentration and extermination camps. The discussions included plans for the implementation of these policies across German-occupied territories, highlighting the regime's intent to eliminate the Jewish people entirely.

The other choices reflect significant historical events but are not related to the specific agenda of the Wannsee Conference. The establishment of the Nazi Party occurred in the early 20th century, while the strategy for invading Poland was determined in 1939. A peace treaty with the Allies was not a relevant topic during the war, especially given that the meeting in question focused solely on insidious plans for genocide, not diplomacy or military strategy.
