ImperialisSMP is a modded nation based survival server where players build countries and try to survive while politics and war shape the world.

The server starts in a Napoleonic era vibe so it is all about revolutions big alliances and conquest. Players make treaties in councils and then sometimes break them when it helps.

There is era progression so nations can move forward through history as the server evolves. You can fight wars lead armies and take land or you can focus on diplomacy and keeping the peace.

It also has economy and trade with things like resource management and taxation. It is not cracked so you need a real Minecraft account to join.
