We have had this type of thread with US Presidents and UK Prime Ministers before, but never with German Chancellors. Let's change that!
For our first list in this thread, let's assume that there had never been events that were so major that they could have the potential to disrupt the line of succession of the German government. So, no lost world wars, no revolutions, no civil wars - at least for the first list.
One more restriction: The lists should start with Otto von Bismarck in 1871; besides that, it's open to you. Footnotes are welcome!
Alright, let's begin with the first list:
1. Otto von Bismarck (Conservative Party); 1871-1894
ADDENDUM: I know that these lists start before 1900 and should therefore possibly go into the pre-1900 subforum. But since the majority of the Chancellors in these lists will be from post-1900 dates, I decided to put it into this subforum here. If this was a misjudgement on my side, the thread could very well be moved.
