This is a modded Java server called Geopol Reforged and it is all about history themed gameplay. The server uses mods that match different historical time periods so it feels like you are playing in a changing world.
Players run the economy and players also create and lead nations. There are wars between nations and different warfare systems so fights actually matter. There are server wide events and the staff also builds lore for the world so stuff that happens can become part of the story.
The map is not a copy of Earth and it uses terrain generation mods so the world looks different from normal Minecraft. It is a PvP server with warfare and there is no unsanctioned griefing. That means you can fight and raid during war but you are not supposed to randomly destroy stuff for no reason.
The server is for players who are 16 or older. It is on Minecraft 1.20.1 and it has netherite gear and guns but the guns are toned back so it is not totally crazy. There is a grace period and similar protections at the start so new players can get set up before big wars begin.
The discord and the server are still in a startup phase so they are looking for admins playtesters and mods. If you like nations economy roleplay and war this server is built for that style of play.
