I found a growing nation called Rio de La Plata on a server named DiplomaticaMC. It is an earth style server where people care about politics and government and it feels like joining a real country in Minecraft.
You can become a citizen in a town and build up your own business stuff. If you want more power you can become a mayor and get funding to help your town start growing.
If you like politics you can run for office or start a political movement. The server also has a unique war system and it is crossplay. People say the community is very friendly.
Build a Nation With Real Politics

I found a geopolitical roleplay server called EarthPol that uses a 1 to 326 Earth map. Players make nations and do politics and diplomacy with other groups.
There is a nation based on Louisiana and they are trying to grow it. They are building a New Orleans style town with ports and more builds.
They want more players to help found new towns in Louisiana and they can fund it with gold. It sounds like a server for people who like roleplay and building and also arguing in politics.GG.MINEWIND.NET New Server IP
