Not at all related to my TL, but what would be the effect of no Napoleonic Wars for Russia? What would Tsar Alexander do? Would he even attempt expansion into the Ottoman Empire like he did IOTL, or would Britain intervene in such a timeline?
For specific timeline details, Napoleon doesn't become First Consul and the French Republic still exists. Western Europe is peaceful for the rest of the early 1800's.
How exactly the Republic exists AND at peace with everybody, especially Britain? The Austrians could be beaten into a prolonged peace or it can be assumed that, after the French are being kicked out of Italy in 1799-1800 some kind of a mutually acceptable arrangement is achieved. But the Brits are totally different story: French Republic can't do them enough harm to kick them out of the war. Not that the Republic was a peaceful state: the Directorate had no idea what to do with its armies in the case of peace and no clear plan for a peaceful existence. Wouldn't it be more realistic to assume that at least war with Britain is going on, at least formally but there is no continental enthusiasm for the anti-French coalitions (without Nappy, Austrians are back in Italy so there is no real reason for them to keep fighting)?
To start from the beginning, in OTL war of 1806 - 12 had been declared by the Ottomans encouraged by the Russian defeat at Austerlitz (and incited by Nappy). So, if there is no Nappy and Russia is not participating in the anti-French wars then there may be:
(a) No Ottoman war whatsoever.
(b) War happens by the Russian initiative and it is much shorter and ends much worse for the Ottomans. Scope of the Russian acquisitions is anybody's guess but I'd assume that they'd be mostly on the Caucasus. Perhaps declaring the
Septinsular Republic completely independent from the Ottomans and its expansion all the way to Crete and perhaps even inclusion of Morea, depending on how badly the Ottomans are beaten elsewhere. If there was ever a good time for the "traditional idea" of getting the Straits, that would be it with all future problems like supplying Constantinople (renamed back from Istanbul) and maintaining enough troops and fortifications in the area. Britain would not be able to do anything significant to prevent this from happening.
Then, of course, goes Sweden. In OTL
Gustav IV Adolf started war with Russia (and lost Finland) because he was unhappy with a request to abide to the conditions of Tilsit Treaty. It is anybody's guess if the war happens in that timeline, which means that Finland may remain in Sweden.
There could be war(s) with Persia (as later happened in OTL) with acquisition of Armenia and Azerbaijan (or something like that) and perhaps an earlier push toward the CA.
Strictly speaking, none of the above would be inevitable because Russia would be better off staying in peace and selling its goods to everybody. I would not expect something as significant as emancipation of the serfs (which means no earlier industrial development) but, with enough of a free time on his hands, Alexander would probably manage to ...er.... "drill army to a clockwork perfection", which he started doing as soon as Nappy was defeated in 1814.
