Magyar Madness
But the Huns precluded Hungary (because there are plenty that would confuse the two, I'm sure), and there is likely some reasonable reason for Poland's exclusion.
1.The Axis powers were called Huns in WW1.Plus modern media seems to just lump them together and that never helps people learn the difference that Huns spoke Hunnic and Hungarians speak Finno-Uglar based langauge is just the main difference alone.Plus don't forget that Huns were Asian and Magyars just decided to settle in the "Huns" land.
If anything the Kzahks should be in the game since they shaped both Eastern Europe and the Middle East,but that won't happen since people can't even figure out who the Huns are.
2.As for Poland they are waiting for DLC just like Hungary...
EDIT culture time
Also food for thought Black Metal music from Sweden has influenced not only American metalheads,but also Brazilian metalheads and Japanese and yada yada....
Just saying that even today or in the 80s or even in the 1700s Sweden had Cultural sway in not only their backyards,but in their continent and even now globally...
