Okay, this is basically as it says on the tin, mostly.
This is actually an idea I have been seriously contemplating devoting to a TLIAD one of these days, but for now, let's just stick to discussion: what if France had kept its monarchy(albeit with reforms), but it was Germany that had a revolution, or revolutions, of sorts, and became a republican state?
The POD, can be anytime between 1747, and 1788, the year before the French Revolution started.
