Siege of Budapest
Father Kun's cassock is currently on display at the House of Terror in Budapest. In his bestselling history of the Siege of Budapest, Hungarian historian Krisztián Ungváry describes Kun's crimes in detail. In the process, however, he also comments that, while Fr. Kun and his unit were massacring Jews, the Papal Nuncio to Hungary, Mgr. Angelo Rotta, was working closely with Raoul Wallenberg and other neutral diplomats and helped to save tens of thousands of Jewish lives.
