Although Ferdinand too came from an old aristocratic family in the German lands, he was now the King of Bulgaria. The core interests of his branch had gradually shifted from the Austro-Hungarian Empire to Bulgaria. So no matter how desperately the Germans courted death, it had little to do with him!
