barbarian factions can't build large cities?

I am playing a few campaigns atm, but lusotana can't build beyond minor cities. it stops at 12000 pop, doesn't go any higher. I just looked through the building tree for it, and there is nothing after minor city lvl. why is this so?

just checked, but it seems like all barbarian factions can't do it. I was gonna try to play gauls next, but how are th gauls suppose to satisfy the huge city requirements for the reform? I mean it requires large cities no?

Are you saying that you can't build large cities or that you can't get to 12000?

Barbarians can build large_city but not huge_city. The reforms only require large cities.

oooh, thx for pointing that out, I guess I was confused. I could get to 12000 pop easily, thx for the fast reply.
