Yeah, but one could say that it was dead long before the 1806 date, cuz' the Reformation and the subsequent wars effectively killed the Empire. As Voltaire would say on his time "The Holy Roman Empire is neither Holy, nor Roman, much less and Empire", or something like that. What Napoleon did was practically to make de jure the existing de facto situation.
That was funny as hell. And true. It was a cheap ripoff of the actual Roman Empire.
Yeah. An example of this was the way in which the French armies (both during Louis XIV and the Revolution) ravaged the Palatinate at will under the impotent nose of the emperors of the time.
