Nation

by TMagic20

Nation adds a nation management system for multiplayer servers, letting players form organized groups that govern territory, diplomacy and warfare.

ForgeNeoForgeClient and serverAll rights reserved1.20.1 – 1.21.1

What it does

Each nation is organized as Leader, Co-Leader, Officer and Member roles, so members can be given a defined rank. Diplomacy covers war declarations, peace treaties and formal alliance proposals, and on-screen alerts with custom sounds report war, peace and alliance changes as they happen. The main interface opens with the N key.

Nation requires Xaero's World Map to run, and it integrates with Open Parties and Claims as an optional dependency: with that mod installed, party membership syncs automatically when members join or leave a nation. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, with 1.0 for 1.20.1 and 1.0-beta for 1.21.1 as the latest builds. The mod is All rights reserved and not open source.

Key features

  1. Nation management

    Nations are created and run by players, with each member holding a rank in a fixed hierarchy.

  2. Diplomacy and conflict

    Players can declare war, propose peace and negotiate alliances through formal proposals that other nations answer.

  3. Immersive notifications

    Alerts for war, peace and alliance events appear on screen and are accompanied by custom sounds.

  4. Open Parties and Claims sync

    Built-in integration keeps nation membership in step with OPAC parties without manual updates.
