How to choose nation?

[nardavin]

I see everyone talking about their nation, I am not sure how to pick one. Is there some requirement to pick my nation such as what age I am in? (I'm in bronze age right now) I may have somehow accidentally chosen without realizing. Help?

you pick when upgrading to iron age
