It's a shame and they also killed the wife of Emperor Franz Josef. He was a saintly man and a Habburg. Kaiser Wilhem Der Grosse on the other hand was probably the worst ruler that Germany ever had. His incomptence made possible the war that destroyed the Austrian Empire and by the end of World II Europe.
"the Emperor Karl learned of a plan of the German High Command to use revolution as a weapon by sending Lenin and other Bolsheviks into Russia so that Russia would be turned upside-down by revolution and thus knocked out of the war. Karl strongly opposed this dismal and short-sighted plan and refused to allow the train carrying Lenin's entourage to cross the Austrian frontier. (What an infamous train-load! The Russian people needed it like they needed a shipment of bubonic plague germs.) Rebuffed, the German government sent the train through Sweden instead. Years later, the Empress Zita said her husband had refused to act in a way that would be "unfair and irresponsible" to the Russian people. Surely, here is wisdom and goodness blinded into a courageous stand against powerful Berlin.
They even established a communist state in Hungary in 1920 only 2 years after the war, the president of it I think was a Jєω named Bela Kun.
