I found a brand new Minecraft Java Edition SMP that is 18+ and it is running All The Mods 10.
The world is fresh and the borders are meant to be claimed so people can build nations and empires. It feels like the server is about progression and big plans like tech and magic and huge builds.
PvP is not random chaos. Wars get declared between nations and there are raid windows so fights are organized. Battles can decide territory and resources and reputation.
A lot of the fun is the politics. Rivalries happen and alliances can form or you can stay independent and build your own peaceful corner.

UnitedFront is a survival multiplayer server where players run the world through nations and politics. People make alliances and deals then they break them too. It feels like the map changes because of what players decide.
You can create a nation or join one and help shape a government or political system. Wars can be declared and fights happen for territory and borders. The economy matters too since trade and control can turn into power.
It is made for serious competition with structured progression. The server is for 1.21+ and it has crossplay. It also says there are no map resets so your empire can last.GG.MINEWIND.NET New Server IPAtlas MC Towny Earth Power Politics
Atlas MC is a new Towny Earth server that is all about geopolitics and nations on a real life map. You pick a real city or town to start and then you expand until you control a huge area.
The server has custom plugins that change how politics feels. Towny Geopolitica lets players make vassals claim titles and try to become a great power.
There is also a system called Battle Points that tries to mix pvp players with normal players in a resource focused way. You can declare wars for land riches or renown. You can stay peaceful or fight your way up.
It is in beta right now and they say joining early will get you rewarded when the full release happens. They also say the hosting is top tier for smooth gameplay.GG.MINEWIND.NET New Server IP
