text: Von Papen, an authoritarian, conservative Catholic, more than any other individual was responsible for Hitler's appointment as chancellor. To be fair, the German Catholic parties disliked Hitler but grossly miscalculated him and the conspiracy against Chancellor Kurt von Schelicher. Anxious at the possibility that Papen, from whom they were estranged, might be reinstated as chancellor and resort to extra-constitutional rule, the Catholic parties agreed to support Hitler and what they believed would be a parliamentary cabinet that would afford them a check on his power. But they got played.
  
  Every single one in the tiny group of men who determined the fate of Germany and the world believed they could control Hitler in his role as chancellor. It's chilling to contemplate.
