One thing in your essay I'd like to point out, that in no common definition Friedrich - Wilhelm II or Otto von Bismarck can be defined as fascist.

they were monarchs, and leaning to the standard absolute monarchy style of leadership whenever possible.

classical Mussolini fascism is corporatism combined with nationalism and elements of communism, mostly in whatever combination The Leader thought were appropriate.

there is no way the Junker class of Prussia would let a bunch of upstart capitalists tell them how to run their empire.
