sorry to not post in Spanish but it's probably better than I don't pretend to be able to.
It looks like that Devs (through an email from Philippe Thibaut) wants the Region Names to be historically correct in all languages. Given the scope and the amount of entries, only a community wide effort could gather the required level of knowledge to get a practical before 2020.
So could you guys please check the regions where Spanish were spoken in 1914 and post your observations to help improve the game in that regard?

Thanks for any help you could provide.
