HOI4: Romania Balkan Dominance guide as a King's Day Special!

Let the party begin! It's King's day today in the Netherlands (or it was on april 27). And since I did the Dutch Queen last year, this year I'll do that partying addict King Carol of Romania. He wants the entire Balkans in his party. And after that? Come and see!
All DLC's were used for this video, historical focuses are on.
The portrait of Carol (minus the party hat) is made by George from Reddit
The music is from Age of Wonders
