Who was the primary leader who took power of germany and what was the name of his political party?

The primary leader of Germany was the Fuhrer Adolf Hitler who led the Nazi party.

Hitler I think.. I'm not sure but he was in charge of the Holocaust and the deaths of 6 million Jews. He committed suicide later on because he saw Mussolini getting publicly executed and he didn't want to deal with that so he committed suicide. I think he shot himself but I am not 100% sure. Hope this helps!!
