I'm looking for a manga which is similar to the early stages of Eden no Ori where there were tribes of people. Maybe historical ones. Preferably shounen, a bit of romance perhaps but if there isn't any don't matter. some Supernatural... 5d3z42

Similar genres/categories to cage of eden:
7 seeds
Drifting classroom
Animal country though that's more tribes of animals led by people....
The way of Ryu
Gringo 2061 seems to be heading in that direction, but not enough of the world has been shown for it to be definite.
51 ways to save her is pretty tribal...well, in that they form haphazard groups in the ruined city.
Sprite? maybe, though its more that they form a haphazard group and the locals form the other.

Historical:
Heaven's Door (KOIKE Keiichi) literally about a tribe in the Amazon.
Otoyomegatari about tribes in the middle east.
Majo
Shut hell
Tenma no ketsuzoku
Choukakou isn't solely tribes though.
Agrippa
Kingdom has tribes but mainly about states and cities.

Fantasy world:
Rure
God Pretender
Takeru - Opera Susanoh Sword of the Devil
Red erewhon
Magi - Labyrinth of Magic
Drifters? has various tribes, but also cities and countries.
Kazan? Its villages but it is quite similar to tribes, has that feel to it.
Jyu-oh-sei (though more a sci world)

Other:
Bokura no kiseki is in a school but the class starts forming its own groups and 'tribes' after they all find out that they were reincarnated from their previous life in a medieval castle.
