Did Nietzsche refer to the disease version of God (the fact that by the days of Nietzsche, Germans had found a cure for neurological Taenia Solium) or is he referring to the political definition of God (a king or an emperor).
In the later case, was he referring to the Chinese (opium war) or the French Bourbon (French Revolution).
The only war that is concomitant to Nietzche's statement are the Opim War or the fall of Napoleon III...
I am inclined to believe in the political version as the Germans had a cure for Taenia Solium long before the XIXth century, at least as a people...
