Coat of arms of Kingdom of South Slavia, German vassal in the Balkans.
South Slavia was made from Kingdom of Croatia and Slavonia and Kingdom of Dalmatia which found themselves occupied by Germans during the dissolution of Austria-Hungary. Few months later Serbia (at least what was left from it) and Montenegro joined the federal kingdom.
South Slavia is divited into seven states: Croatia, Dalmatia, Slavonia, Serbia, Montenegro, Bosnia and Herzegovina.
Slavonia, Dalmatia and what remains of Croatia all as own states, but Serbia as one state? Hm. Doesn't seem very balanced, but I guess it makes sense if this Yugoslavia is in fact Croatian-dominated. Anyway, nicely made. I like this style of CoAs, with good quartering and all.
