This list is WIP:
The country/region marked in bold is the main country, while other countries/regions are secondary, and less important for that country/region (for example hr:Mordvinski jezici, English: Mordvinic languages, is more important for Erzya than Russia). Bashkortostan, Don Region, Erzya, Tatarstan and will always be given advantage over Russia. Republic of Srpska (Republika Srpska) is only present for one article, hr:Filip Višnjić. He's assigned with the Republic of Srpska because he's a Serb from Bosnia and Herzegovina (Republic Srpska is the entity of Bosnian Serbs). Articles that don't have English language versions will have their names translated into English. The translated names are located next to the Croatian name.
