What do you unification and dictatorship have in common? Or better yet what is the connection between the two? Germany Unified over 60 years prior to Hitler's taking power and had already undergone one change of government without fragmenting. I don't understand how you connect the two, please enlighten me?
One other thing, in your linked article you claim that the 39 states of Germany were created by the Congress of Vienna, that is false, they were created by Napoleon when he consolidate his power after conquering Germany in 1805-1806.
