Croatian Kingdom in an Austrian Triple Monarchy

Ethnic map of a proposed third land inside Austria-Hungary, namely Croatia. The Kingdom of Croatia-Slavonia, Bosnia and all of Cisleithania south of the Drava and south east of Villach were united into a single South Slavic kingdom as a counterweight to Slavic nationalism and the Kingdom of Hungary.

Most data is from the actual Austrian census held in 1910, though I had to patch it up with other sources too, so don't take this map as representing any real ethnic division at the time. Minorities are favoured. (some of those pink coloured parts have less than 30% Italians, for example)

Blue - Croats
Green - Serbs
Brown - Bosniaks (called Muslims here, since the term Bosniak came later)
Orange - Slovenes
Yellow - Germans
Pink - Italians
