Depends on what kind of government the countries of Ishgar have although they're in the medieval/steampunk era of sorts. And yes indeed, it's just Fiore vs. Alvarez. The rest are probably ignored or destroyed along the way. Bosco was one of them.

That would make a whole lot sense if Ishgar's countries are allied in trade and non-aggression pacts together. There were little info regarding about the neighboring nations next to Fiore, the main setting of the series.

Actually, there were 730 Guilds in Alakitasia that were all merged together with Alvarez alongside the former nations of the Western Continent absorbed.
