Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
It was not at all unusual for men of supreme military and political accomplishments to be granted with the highest echelons of nobility. For example, in 1871, after spending decades working to unite the German States into a single Empire, Otto von Bismarck was granted the title of Prince.
He was also later also given the title of Duke. Considering the man came from origins similar to Bruno, this was indeed a significant accomplishment. Bruno was now a Prince of Russia, a hereditary title that his family would hold in the Russian Empire so long as it lasted in this timeline.
