Wiki gives us one small line that begs to be expanded. Working on getting a copy of the source, "Rhineland radicals" by Sperber.
"The economic, social and cultural dislocation of ordinary people, the economic hardship of an economy in transition, and the pressures of meteorological disasters all contributed to growing problems in Central Europe."
"The Long Nineteenth Century" by Blackburn is a general history of Germany, ending with WW1. You'll find plenty of information to get started in the book, as it is well sourced. I don't recall it being too specific in that area, but would certainly not hurt to start your search.
Additional question (if permitted by mod overlords, please delete if not): is there a good english language book on this that does not look at this purely in reference to the lead up to the world wars?
