How do you see France progressing from there?
IMO economic policies would resemble OTL path, since many of Nappy III’s policies were actually initiated under De Cavaignac. But there would be no reconstruction of Paris at OTL scale.
Other domestic policies, I think the most significant butterfly would be an early introduction of universal state education system (IOTL it was introduced in 1880) to promote republicanism in younger generations.
Foreign policies would be very different, since Napoleon III totally dictated France’s foreign policies IOTL:
- There would be no Mexican expedition and no Second Mexican Empire (totally a Bonaparte brainchild), and thus France would have taken a more pro-Union stance on ACW.
- No occupation of Rome which pissed off Italians a lot and prevented an alliance with Italy. On the contrary, the Second Republic could shore up the Roman Republic and keep Italian republicanism alive. In the maximally optimistic scenario, France could help drive Austria out of Italy. A friendly Italy would be very valuable to France.
- I think TTL France would focus more on colonization in Africa and Asia and less on Continental Europe. Likely no French participation of Crimean War.
- Bismarck would find it harder to pick a fight because ITTL a Republican France would have very different foreign policy priorities. For example, it would care less about monarchist succession in a certain country.
