This server is called Realm of Nations SMP and it is all about countries and politics in Minecraft. When you join you can become the president of a country or just be a citizen in one that already exists.
Players can trade with each other and also battle other nations if they want. It is kind of like a big world where every group is its own nation making deals or going to war.
It looks like a good server if you like survival with more strategy and roleplay about countries instead of just normal pvp.
