Kingdom : Civilization Expansion

by OmegaSyi

Kingdom: Civilization Expansion turns villages into growing kingdoms with rulers, armies, economies and diplomacy for NeoForge worlds.

NeoForgeClient or server, optionalAll rights reserved1.21.1 – 1.21.11

What it does

The mod transforms Minecraft villages into living civilizations. Each village can evolve into a kingdom with its own government, leaders, armies, economy and territory. Players can join a kingdom, gain reputation, command soldiers, build defenses, form alliances or conquer rival nations, while wars, sieges, trade agreements and military ranks shape how each kingdom develops over time.

Kingdom: Civilization Expansion is intended as a grand strategy layer inside Minecraft. It adds a live HUD that shows a kingdom's status, wealth, military strength, diplomacy and population, a guide book, and rebellions and civil wars that can split a realm. Dynasties age, and a ruler who dies is followed by an heir. The mod runs on NeoForge only. It works on either side, and neither needs it, so it can be installed on a client, a server or both. Files are published for 1.21.1 – 1.21.11 under All rights reserved, and the mod is not open source.

Key features

  1. Kingdom creation and succession

    Villages develop into kingdoms with rulers, and a dynasty system passes the throne to heirs as rulers age and die.

  2. Wars, sieges and diplomacy

    Kingdoms declare wars, raid territory, conquer rivals, sign peace treaties and form alliances with other realms.

  3. Recruitable soldier armies

    Soldiers can be recruited and ranked, and commanded to defend borders or attack rival territory.

  4. Economy and reputation

    Kingdom economies track wealth and trade, while reputation and influence determine how other realms respond to a player.

  5. Quests and world events

    Legendary events such as dragon invasions, plagues, famines and meteor strikes require kingdoms to respond, alongside quests tied to world progression.

Questions

Does Civilization Expansion need to be installed on the server?

No. It works on either side, and neither needs it, so installing it on a client, a server or both is enough for its features to work in that setup.

Which loader does Civilization Expansion support?

The mod is published for NeoForge only, across 11 release versions 1.21.1 – 1.21.11, with 1.2 for 1.21.11 as the latest file.

Can rulers die and be replaced?

Yes. The dynasty system lets rulers age and die, with the throne passing to heirs, which keeps political control changing over time.
