Raoul Wallenberg was a Swedish special envoy to Hungary who devoted himself in the last few months of 1944 to save many Jews from being deported to concentration camps. Wallenberg was a businessman who could come and go between Sweden and Hungary, as Sweden was neutral in World War II. Hungary was technically an ally of Nazi Germany under the rule of Miklos Horthy, then became an uneasy ally, then became a puppet state of the Nazis in 1944, after Horthy sought peace terms with the Allies. In the summer of 1944, under the leadership of Adolf Eichmann, Nazis in Hungary deported over 400,00 Jews in just a few months. Raoul Wallenberg came in July of that year specifically to help Jews, which he did by giving them special passports in the name of Sweden. He was remarkably successful, helping thousands, Yet, for reasons that might forever remain unknown, once the Soviets took over Budapest in December 1944, he was seen as a problem and Wallenberg was never seen after visting Soviet Authorities.
