Who were the implementers of the final soliution?

The implementers of the Final Solution were primarily the Nazi regime's leadership, including Adolf Hitler, Heinrich Himmler, and Reinhard Heydrich, along with various government agencies and organizations like the SS (Schutzstaffel) and the Gestapo. They orchestrated and executed the systematic genocide of six million Jews and millions of others deemed "undesirable" throughout occupied Europe during World War II. Local collaborators and administration in occupied countries also played significant roles in the implementation of this horrific policy.
