Finland could get a sisu style bonus to defence

Zulu should get a buff to Draftable Battalions and Offense

Norwegian Hydropower:
Bonus to Hydropower energy production.
Bonus to steel refineries and artificial fertilizers, to represent aluminium industry and heavy industry dependent on the hydropower.
If possible negative impact on urbanization, as the creation of these plants in nowhere heavily interrupted urbanization.

Serbia: The Serbian Revolution

+15% Army Defense
+20% Petite Bourgeoisie strength

+25% Law Enactment Time

The reasoning behind this is that the 1836 state of Serbia is the result of the Serbian Revolution, which liberalized Serbia and granted it great autonomy from the Ottoman Empire. The 1835 constitution of Serbia was very liberal (radical) at the time, since it abolished serfdom and instituted a constitutional princedom with voting (although Russia, Austria and the Ottomans forced Serbia to repeal that constitution and made them adopt an 1838 "Turkish Constitution", which was still pretty liberal and allowed voting, but not enough to give people under autocracies any ideas). The Army Defense bonus is the legacy of the Serbian Revolution, mainly the First Serbian Uprising part of the revolution, which represents the superb fighting capabilities of the Serbian army in face of the opponents which outnumbered them constantly (which also carries over to WW1). The Petite Bourgeoisie political strength is the representation of the people who were actually the wealthiest at the time in the Princedom: merchants. Many people in Serbia got rich off of trade, mainly salt and pork, with the leader of the First Serbian Uprising being a pork merchant himself. PB ideologies also represent the dominant sentiment of the population: reactionism (monarchism), patriotism and meritocracy. As for the law enactment time penalty, it's a representation of the absolute clusterf*uck that has been the Serbian National Assembly, which always took their sweet time to agree on literally anything, and under a very autocratic prince Milos Obrenovic was even ignored at the time. The principality was still considered an autocracy until the 1838 constitution came to power, which officially established democracy in the country.

@StivKobra Great stuff. Will add Serbia in the next update.

how about one for Texas?
pulling on the "lone star state" idea by giving them a buff in defense, migration, and oil production, along with more power to the landowners and a Diplo debuff.

@Jimmteycreeper17 Sure I can add it in the next update.
