Geopolitical Warfare is a NeoForge 1.21.1 mod for multiplayer nation-building, territorial expansion, diplomacy and fair modern warfare.
Create your own country, choose a unique 1–3 character tag, invite members and build a capital. Every country starts with protected territory, and members automatically receive their country tag in the player list.
Claims are chunk-based and must connect to existing territory. A country can only have one empty claim in progress at a time, and it takes 24 hours to complete by default. Territory limits scale with country membership, preventing one player from claiming the entire world.
Countries can declare war, make peace and capture enemy border chunks. Captures take time, defenders can contest them, and a successful conquest triggers a cooldown before the next one. Offline protection prevents countries from losing territory while none of their members are online.
Use temporary particle borders to see the limits of your country, and receive a message whenever you enter a country or the Wilderness.
Main commands:
/country create <name> <tag>
/country invite <player>
/country claim
/country borders
/country declare <country>
/country capture

/country info
All major timings and limits can be changed in the server config.
