so essentially the SDS is like a growth in the balkans lf I understand this correctly, not really similar in any way to their hellenized brothers and somewhat hostile but not worth the hazzle to stomp out.

I also have some questions about the flag designs

The SDS has the flag of the communist people‘s republic of serbia which in return had the tricolour purely because of the existance of the tsardom of russia. Does this imply that the pan-slavic tricolour, white blue red and its different combinations also can be traced back to a slavic empire of similar importance to the russians in otl?

the Rhomanian flag looks like the byzantine flag of otl except different colours, what does the Blue and white represent? I am assuming it stands for the ocean and the sky

very interesting! I really love this take on the balkans since it usually gets basterdized to „big yugoslavia“, „big serbia“ , „big croatia“ or kosovo war electric bogaloo. It‘s a pretty unique take so I love it, especially the idea that Yugoslavia is not a mix match of people that happened to be called south slavs but actually their own people and identity!

If you don‘t mind I have a few follow up questions:

Does the SDS have any claims on the Rhomanians or official standing on its existance? You mentioned that the Rhomanians were hellenised/romanised as well as that there are south slavs, I would assume that the SDS would have a „save our brothers from the hellenic menace“ mentality similar to OTL Yugoslavia wanted to remove religion as widely as possible (assuming that hellenised/romantised in this context means a more different culture but still similarities like language and traditions for example)

I assume that the Rhomanians are a tsardom either in name or an actual one due to having tsar at least partially in their name as well as generally a different ideology. Do they see each other as enemy and if so which of them is military wise the stronger opponent

What sort of leftist state in it as in is it completely stalinist, some form of titoist or as tame as a social/socialist democracy?

How much influence does the SDS have over the balkan and are there similar communist supporters in the Rhomanian and Romaion states?

I have a few questions for the balkans! For one did Yugoslavia exist in this world, I don‘t think so but instead of speculating I would like to hear an absolute answer from the most authentic source the author. Another question would be what the people/ethnicities of is SDS (commie serbia flag) are. Lastly what are the relations between the Tsarigratia and Rhomaioan as well as why the tolerate a communist country at their border
