After German occupation, Hungary participated in the Holocaust. During the German occupation in May–June 1944, the Arrow Cross and Hungarian police deported nearly 440,000 Jews, mainly to Auschwitz. Nearly all of them were murdered. The Swedish Diplomat Raoul Wallenberg managed to save a considerable number of Hungarian Jews by giving them Swedish passports. Rezső Kasztner, one of the leaders of the Hungarian Aid and Rescue Committee, bribed senior SS officers such as Adolf Eichmann to allow some Jews to escape. The Horthy government's complicity in the Holocaust remains a point of controversy and contention.
