Ah, that patrician ancestry could explain why the Praetorian Guard helped Claudius to ascend to the throne. The Praetorian Guard acted in a way that our current ‘Field’ FBI is acting today.
He was the only male left in the imperial family when Caligula was assassinated...the Guard wanted to keep their jobs and privileges so they wanted the system created by Augustus to continue. The Senate debated restoring the Republic...the Guard did not want that.
