I was bored and it's been a while since I don't make any maps... So, here's the story:
In this TL there was never a significant downturn of the French navy in the First Empire (French victory at Trafalgar?), even though Britain continued to be major naval power outside Europe. By the early 1820's, both nations signed a substancial truce when the French made some concessions (economic, mostly), starting a long period of "armed peace". A cold war, which would get hotter sometimes, but that would endure all the 19th century. In this context, a "prestige war" started when the British started the construction of the Nicaragua Canal by the 1850's followed by the French answer with the Suez Canal. It was only the beginning of the 19th Megaprojects...
Algeria conquest took place for the same reasons as OTL's and its settler population is boosted by all dissidents of the Napoleonic Regime. By the 1870's one of the following Napoleons started the ambitious plan of constructing a
Canal to the Saharan Salt Lakes and create a new agricultural frontier, his plan was to make a major change all over the North African climate and start cultivation of cotton in French land to even the growth of the clothing industry.
The succeful replenishment of this new sea gave birth to new rivers and lakes all over Algerian hinterland. Then, the region would see a massive overflow of gouvernement-sponsored European immigrants occupying the traditional homeland of the natives, that started to intensily revolt as they're pushed into some less fertile areas.
As you can see in the map, Tunisia was early incorporated into French North Africa. There's also a mix of Bantustan/Princely State for the Berbers (a OTL's project of Tocqueville IIRC), which was made to divide them from the Arabs and bride their support (a falwed plan after the construction of the Inner Sea). Yet, you see that that there's some sort of Crémieux Decree in TTL, but that failed to get the Muslim's support (only about 4% of them became French).
It's 1890 and the situation in French North Africa is explosive. Land conflicts between the
colons and the
indigènes are common and the Empire even fears for the integrity of the Canal itself, establishing a strict Military Regime over the Inner Sea Area.
Here's the map, enjoy it:
