This time, unlike my last TL, I want to avoid France's dramatic population lag and confirm them as the #1 Power, more effectively neutering the UK and Russia.
The lore this time is simple. I want to prevent Napoleon's four greatest mistakes.
1. Not Dismantling Prussia.
2. The Continental System.
3. Invading Spain.
4. Invading Russia.
(POD) In 1806, Austria joins the fourth coalition. As a result, however, the allies are even more cocky and less coordinated, allowing Napoleon to still achieve all victories from the IRL 4th and 5th coalitions combined. This accomplishment greatly stresses Napoleon, whose patience snaps after Freidrich Stapps' failed assassination attempt. Napoleon dismantles Prussia (strike 1), with Austria only saved by offering Marie Louise's hand in marriage. The Franco-Russian alliance only survives because Napoleon promises to immediately assist in the Russo-Turkic War
As Prussia is destroyed, Austria petrified, and Russia allied, Napoleon's anti-British sanctions are mild, since there is less need to stop trade (strike 2). As Portugal is still an outspoken British Ally, Napoleon still occupies Portugal with Spain, but does not seize the throne, as he considers Iberia beneath him, and instead turns his gaze to the Balkans (strike 3).
The Ottomans are steamrolled by the combined Franco-Russian onslaught, pushed fully out of Europe. Soon after the war, the alliance falls apart over disagreement of control of New Byzantium and the Bosporus, starting the 5th Coalition. Alexander, high from overwhelming victory, is the aggressor, and Napoleon destroys two Russian armies before seizing Vilnius Alexander is forced to make peace. The loss of Lithuania leads to his assasination by Russia's francophobic nobility, who then force his brother and new Tsar Nicholas to join the British in a 6th coalition. This fails catastrophically, with Napoleon seizing everything west of the Dneiper and Daugava rivers to serve as a buffer for the newly created Poland. Britain finally sues for peace in 1814 at the Vienna Conference, ending the coalitions.
The map above is the draft, and I want advice on the circles in particular (or sometihng else very glaring.
1. The original Franco-Spanish treaty carved Portugal into kingdoms under Spanish influence that would revert to Spain if there was no heir. How does this look? Also, if he doesn't pick his brother, who does Napoleon choose to rule Spain in the arbitration?
2. The Balkan borders are based on Catherine the Great's Greek Plan. I figured Alexander I would love to fulfill his beloved grandma's dream, and I figured Napoleon would agree as he would want Austria to focus on the Balkans and not Italy or Germany.
3. How plausible is it that after Nicholas fails in the 6th coalition that there is a civil war and Napoleon props up a pretender in St. Petersberg?
4. Is it even possible to weaken Russia to the point where Qajar Persia can retake land from them?
I know 3 and 4 are a stretch. I want to weaken Russia as much as possible, though I know this is absurd. I am looking for advice on how to do this.
Finally, any further advice on how I can realistically weaken the UK and Russia is appreciated.
One idea for the UK is to have them join the Confederates in the Civil War to weaken the pro-French Americans. This causes massive public backlash and helps lead to the UK, not France, having a tendency for protests and riots.
