Creating a new nation/State in editor

Hello
Recently I thought about a pretty nice idea and it requires the creation of a new nation/state in Europe and the creation of two ~ three leagues in there.
I tried to look online tutorials how to create a new nation/state, but did not really understand how.
I'd be happy if someone would help me at the issue.

Thanks a lot and have a nice day

I found a playlist of a youtube tutorials that I used, but can't remember how to do it

Hey David,

This tutorial isn't exact to your needs, and admittedly I haven't finished the series yet myself, but seems a good starting point.....

Thank you, but I think that the best idea is to build my nation on other exist nation, like Iceland, but I got a question - How are the game new players names determined?
Because I don't want "Icelandic" names in my country, I want English names..

As in Episode 1 or 2 of the vids linked above, but don't pick Icelandic players to fill your country.....

Fantasy names NFI soz mate!!
