The basic idea is that in the period around 1750-1800, Europe becomes engulfed in a series of massive, interconnected wars. Much like our world's Napoleonic Wars, these end up drastically changing the map of Europe and the balance of powers. And rather like the Napoleonic Wars, it would pit Revolutionaries against Reactionaries; the dream of nation and freedom against the steel and gold of the old powers. Of course, that is the popular narrative, but countless other scores and feuds are addressed over the war as well. Unlike our Napoleonic Wars, it would be Germany at the forefront of the Revolutionary coalition.
