Were they created there or did they expand there? I believe that War comes regardless of expansion date. "Guys from Sol" vs "Gals from Sol" will be a Civil War. "Guys from Sol" vs "Bros from Achenar" will be a War.
I'll give you another example. Split the US in half, go to war, it's a Civil War. Don't split the US, go to war with North Korea, it's a War. Civil, in this case, usually refers to personal matters or home matters, if you will. The logic is a bit shaky, but I think that's how it works.
