Maybe Polish uprising in 1863, exactly 22 January. It was only againts Russian Empire while there was crimean war. There was plans of Russian legions (Russians didn't liked Tsar that much). There could be way to play as them and send call for peace by event if you capture Minsk, Vilnus, Warsaw. And if you grather Kiev there could be a bonus for some Ukrainian legions (they too didn't liked Tsar). And for sure some National Spirit to make it possible to win (not like confederats). And make Infrastructure lvl 2. I don't think I need to say you to add more military factorys around Warsaw and make a puppet state of Russia. (We was a puppet then the revolt and we disappeard from the map again). Name of puppet state was 'Królestwo Kongresowe' transealting into 'Congress Poland' what SHOULD BE 'Congresionall Kingdom' wierd. Abaut the name if you win the uprising it can be called 'Rzeczpospolita' or just 'Commonwealth'.

These are the leaders:

PUPET LEADER
-Józef Zajączek

DICTATORS
-Marian Langiewicz (first dictator, died 2 years after uprising begun)
-Romuald Traugutt AKA Michał Czarnecki (second dictator, he was Russian general but he was mad at Tsar so he became one of the Polish rebels, he was killed when uprising failed)

GENERALS
-Zygmunt Sierakowski
-Jarosłwa Dąbrowski( he was too Paris Commune Army Leader )
-Zygmunt Padlewski( he got cool mustache!)
-Walery Wróblewski
-Józef Hauke-Bosak

Abaut the support, French was supporting us. They can send volunteers or weapons by the event. The name of party that was rulling was 'Tymczasowy Rząd Narodowy' what means 'Temporary National Goverment'. There could be too event abaut who will rule. There were 2 camps 'Biali' and 'Czerwoni'. What means 'White' and 'Red'. The Biali was trying to negotiate peace with enemys and more co-op with France. Red also liked France but they didn't belived they will help them that much (you know white flag and other memes). So they wantedd to focus on the war with Russia but ONLY Russia. they couldn't fight with Prussia and Austria beacuses they were simply too powerfull(FRANCE NEEDED). So they focused to attack Russia and deal a peace with Prussia and Austria so they won't destroy New Poland.
And at the end I can say that it was the biggest Polish uprising of all time and it failed.

Few more Ideas:
-I remember now that there were wierd polish tanks called 'Kosowóz'. These tanks was made from wood and their pilots shooted from them by the muskets, they was doing well to at close combat with pikes that they picked instead of musket while they were close. Beacuse they were made from wood they was weak armor. Maybe few Polish tanks divisions?

-There were French guys called 'Żuawi Śmierci', elite soliders who fighed on Polish side. They had cool uniforms. http://www.muzeumwp.pl/dictionary/mundur-zuawa-smierci,64,duzy.jpg

-There's some national focuses I thinked out.
Number in front means nothing but '~' means that it allows to make this next
1'Stregcht the rebelion' adds national trail that adds divison recovery speed, max. organisation, bonus manpower% (numbers are the case of balance).
2'Tax the rebelion' (historicaly we really made tax for rebelion and secretly taxed it in the streets) adds some civilan factorys and bonus for -10% (or other) to consumer goods factorys.
~3'New 'products' in Lodz' civilan fabrics in Lodz (make them be here in the begining of game like 5) will change into military fabrics (just these 5).
4'Czerwoni focus' adds manpower% (better balance with first focus) bonus called 'Metody Czerwonych'/'Metods of the Red'
~'Demands to Prussia' give event to Prussia abaut giving Poland: Poznan,Gdansk or giving them casus belli and give them bonus for divison attack 10% for 200 days called 'It's gonna be 1410 all over again.' (It's abaut the 13 years war, the war with German Knights and Poland Lithuania union they won it)
~'Demands to Austria' give event to Austria abaut giving Poland" Lwow,Stanislawow,Krakow,Zaolzie or giving casus belli and national bonus for dvison attack 10% for 200 days like in Prussia (It can seem bit unfair or too fair, but history has too something to do there. Poland-Lithuania helped Austria in their war with Ottomans, it was VERY, VERY BAD for us but we managed to win it (worse with the Sweden and Russian affairs in that time), we was helping to stop the siege of Vien, probably without Poland this sige would be lost, Ottomans in Germany and Poland in small better positon but still VERY BAD. So where's the betray? Well partisipation of Poland, that's why they got our lands LOL.
5'Biali focus' adds 0.5 (or other) bonus for the political power.
~'Negotiations with Prussia' they gets event abaut that Poland wants to BUY theirs lands back (Gdansk,Poznan) for non-agresion pact (usefull when Napoleon gonna expand with Polanish friend) and perk 'Sold Polish lands' -5% (or other) to consumer good factorys and political power 0,25 per day for like 200 days. If they say no they gain remilitarizated these ares beacuse of upset of Pols. (Ya know red can't be always picked path)
~'Negotiatons with Austria' sends them event abaut giving back Krakow,Zalozie,Stanislawow,Lwow for same non-agresion pact 'Sold Polish lands' (-5% (or other) to consumer good factorys, political power 0,25 per day for 200 days) or Remilitarizate these lands beacuse of upset of Pols.
(with remilitarization I mean it will be easier than a revolt, and it will be like fro 5 years all of them, gonna hurt with it if Napoleon gonna invite Poland)
6 Ruin Tsar authority. It will give Russia an event to get -100 saving good name of the Tsar. Get -50% recrutible population factor (nothing for them) for 100 days or -5% national unity.

The number 4 and 5 aren't abel to comply. You can pick only one. Actually there's should be partys for them and bonus for their popularity abaut these focuses and imidiatly change ideology.I heard of you want to add few partys. You know how to call them: 'Biali' and 'Czerwoni' the Biali should be leaded by Marian Langiewicz who was historical one of them. He seems like a man that kills not talk but really he was a carfull man, he died not in battle but in Austria, prison he escaped there beacuse of the bad way uprising went. After a bit of time he died there (killed probalby, no one knew or cared abaut 'ill' that he 'got' probably Tsars men) you don't need to make that in the game. Only if uprisng will go wrong, same with Romuald Traugutt/Michał Czarnecki. He was a guy! A real leader of Czerwoni's camp. He was they guy that wanted death of Tsar. He was a Russian general as I told you who standed againts Tsar.

Ok thanks

Maybe Australia, New Zeeland and cannada should be (as low developed Provinces) a part of GB
To their independence (the data and details for political focusses and ideas I could supply if interested)
Would be just a suggestion.

sorry my english is very bad.
