What significant policy was developed at the Wannsee Conference?

The decision made at the Wannsee Conference in January 1942 marked a pivotal moment in the history of the Holocaust, as it formalized plans for the systematic extermination of the Jewish population in Europe. This conference, attended by senior Nazi officials, discussed the implementation of what was referred to as the "Final Solution." It was here that the Nazis coordinated efforts to deport Jews to concentration camps and orchestrate mass killings.

The context of the conference is crucial; it was not merely theoretical discussions but rather a step towards the brutal execution of policies that led to the deaths of six million Jews. Understanding this event is essential for grasping the scale and intent of the Holocaust, as it highlights how administrative meetings could culminate in horrific actions against entire communities based on ethnic and religious background.

In contrast, the other options do not accurately reflect the historical significance of the conference. Economic alliances, infrastructure reorganization, and military strategies do not pertain to the core decisions made during the Wannsee Conference, which was specifically focused on the horrific plan for the genocide of the Jewish people.
