WI Frederick III lives longer, till say 1898? His son Wilhelm dies of a heart attack or something earlier on so Frederick is succeeded by Heinrich. What would having a longer-lived Kaiser Frederick followed by a Kaiser Heinrich mean for Germany, Europe and the rest of the world? And what would be different by the time World War I comes around?
All I know about Frederick was that he was a liberal personality and all I know about Heinrich is that he was an admiral and a much better diplomat than his brother. But what that would mean exactly in the greater scheme of things, I don’t know.
