Diplomacy

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Forge only.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

The Diplomacy Mod introduces a full political and negotiation system into Minecraft, allowing players and teams to interact through formal agreements instead of relying only on combat. Players can establish alliances, create peace treaties, manage territorial claims, negotiate trade deals, and structure their relationships with other groups in a more strategic and immersive way. The mod focuses on cooperation, conflict resolution, and world-building, providing servers with tools to shape nations, develop stable regions, and manage disputes through diplomacy rather than force. Perfect for SMPs, factions, and large multiplayer worlds where politics and collaboration matter.

Towny inspired me, as I had many good years playing with it on servers. However, I couldn't find a good all-in-one diplomacy system as a mod rather than a plugin, so hopefully this fills the gap!
