Polarization
/Chapter 8 of The Holy Roman Empire: A Short History, by Barbara Stollberg-Rilinger describes how rivalries and warfare between the Empire’s members (most importantly Frederick the Great, King of Prussia, and Maria Theresa and her son Joseph II, Habsburg rulers of Austria), philosophical trends like Enlightenment liberalism, and external events like the French Revolution fatally atrophied the Empire, turning its institutions sclerotic and captive to the ulterior interests of its own elite.
The chapter is called “Political Polarization.” Here’s Stollberg-Rilinger’s concluding paragraph:
With the deaths of Frederick II in 1786 and Joseph II in 1790, the political situation in the Holy Roman Empire became thoroughly polarized. The Austrian-Prussian dualism affected every aspect of the Imperial constitution, and its opposing gravitational pulls, combined with the cynical confessional politics of both sides, tore apart the Empire’s institutional fabric. The weaker Imperial members could not extricate themselves from this polarization and had to choose sides. The powerful Imperial members had long ceased to base their authority and legitimacy on the Empire and consequently had no interests in the Empire as such. Thus, when the continuing existence of the Empire served their particular goal, they supported it, but when it did not, they showed no qualms in attacking or abusing it. At the end of the eighteenth century, all that was needed for the ultimate collapse of the Empire was one final external push.
