Tinto Maps #9 - 5th of July 2024 - Carpathia and the Balkans

Greetings, and welcome to another Tinto Maps! This week we will be taking a look at Carpathia and the Balkans! It will most likely be an interesting region to take a look at, with a lot of passion involved… So I’ll just make an initial friendly reminder to keep a civil discussion, as in the latest Tinto Maps, as that’s the easiest way for us to read and gather your feedback, and improve the region in a future iteration. And now, let’s start with the maps!

Countries:
Countries.png

Carpathia and the Balkans start in a very interesting situation. The Kingdom of Hungary probably stands as the most powerful country in 1337, but that only happened after the recovery of the royal power enforced by Charles I Robert of the House of Anjou, who reined in the powerful Hungarian nobility. To the south, the power that is on the rise is the Kingdom of Serbia, ruled by Stefan Uroš IV Dušan, who has set his eyes on his neighbors to expand his power. The Byzantine Empire, meanwhile, is in a difficult position, as internal struggles ended in Andronikos III being crowned sole emperor, at the cost of dividing the realm; both Serbia and Bulgaria have in the past pressed over the bordering lands, while the Ottomans have very recently conquered Nicomedia. The control over the Southern Balkans is also very fractioned, with a branch of the Anjou ruling over Albania, the Despotate of Epirus under the nominal rule of Byzantium as a vassal, Athens, Neopatria and Salona as vassals of the Aragonese Kings of Sicily, Anjou protectorates over Achaia and Naxos, and only nominal Byzantine control over Southern Morea. It’s also noticeable the presence of the Republics of Venice and Genoa, which control several outposts over the Adriatic and Aegean Seas. A final note: in previous maps, Moldavia was shown in the map, but we’ve removed it from it, and it will most likely spawn through a chain of events in the 1340s.

Dynasties:
Dynasties.png

The House of Anjou rules over Naples, Hungary, Albania, Achaia, and Cephalonia; they’re truly invested in their push for supremacy over the region. Apart from that, each country is ruled by different dynasties, except for Athens and Neopatria, ruled by the House of Aragón-Barcelona.

This week we’re posting the general map of the region, along with some more detailed maps, that can be seen if you click on the spoiler button. A starting comment is that the location density of Hungary is noticeably not very high; the reason is that it was one of the first European maps that we made, and we based it upon the historical counties. Therefore, I’m already saying in advance that this will be an area that we want to give more density when we do the review of the region; any help regarding that is welcome. Apart from that, you may notice on the more detailed maps that Crete appears in one, while not being present in the previous one; because of the zooming, the island will appear next week along with Cyprus, but I wanted to make an early sneak peek of the locations, given that is possible with this closer zoom level. Apart from that, I’m also saying in advance that we will make an important review of the Aegean Islands, so do not take them as a reference for anything, please.

Provinces:
Provinces.png

Provinces! Nothing outstanding to be commented on here; as usual, we’re open to any feedback regarding them.

Terrain:
Climate.png

Topography.png

Vegetation.png

Terrain! The climate of the region is mostly divided between Continental and Mediterranean, with some warmer and some colder regions. Regarding the topography, the Carpathian mountains are famously important and strategic, while the Balkans are a quite hilly and mountainous region, which is also greatly covered by woods and forests.

Cultures:
Cultures.png

Here comes the fun part of the DD: The cultural division of the Balkans! A few comments:
  1. Hungary is full of different minorities. Transylvania, especially, is an interesting place: there we have a mix of ‘Hungarians’, ‘Transylvanians’ (which are the Romanian-speaking inhabitants of the region), ‘Transylvanian Germans’, and ‘Szekely’ people.
  2. We have divided the Southern Slavic-speaking region into their dialectal families of Slovene, Croatian, Bosnian, and Serbian.
  3. The Southern Balkans are mostly divided among Bulgarian, Albanian, and Greek cultures.
  4. We’re also portraying plenty of other cultures, such as Dalmatians, Aromanians, Sclavenes, Arvanites, Cumans, Jasz, or Ashkenazi and Romanyoti Jews.

Religions:
Religion.png

This one is also interesting. Apart from the divide between Western Catholicism and Eastern Orthodoxy, we have the Krstjani in Bosnia, Bogomils (the pink stripes both in Bosnia and Macedonia), and Paulicians in Thrace. The Jewish populations do not pass the threshold percentage to appear on the map, but there are plenty of communities across the region.

Raw Materials:
Raw Materials.png

The materials of the region. Something very noticeable is the richness of minerals, with plenty of Iron, Copper, Tin, Lead, Gold, and Silver. Specifically, Slovakia is very rich, and you definitely want more settlers to migrate to the region, and exploit its resources. The region is also very rich in agricultural resources, as you can see.

Markets:
Markets.png

The region is mostly divided among four markets: Venice, Pest, Ragusa and Constantinople.

Country and Location population:
Population 1.png

Country and location population (which I’ve also sub-divided, and is under the Spoiler button).

And that’s all of today! I hope that you find the region interesting; we certainly think that it is. Next week we will go further south, and we will take a look at the Syrian Levant and Egypt. Cheers!

I just come here to say that I think Budjak/Bessarabia should have a Crimean Tatar culture with low population numbers (almost 0), showing Tatar presence and control in those steppes, excluding Cetatea Albă/Moncastro which should have Italians in it. This will also make it easy to colonise for Moldovian dutchy when Golden Horde is repelled.

Odd. There seems to be some contradictions between the sources.

Machine translation:
To the south, Charles Robert found Serbia, which was rapidly strengthening, to be dangerous. In 1317, he captured the castle of Macsó, and after another Serbian campaign (1319), he restored the Banate of Macsó. In 1320, he appointed Stephen Kotromanić as the Ban of Bosnia, who represented Hungarian interests in the southern regions. In 1324, Stephen also acquired the Banates of Só and Ozora, thus governing a vast territory. In 1339, Dušan Stephen, the Serbian king—whose mother was the daughter of Ladislaus Kán, Voivode of Transylvania, and whose father was Stephen Uroš III, the Serbian ruler—reoccupied the Banate of Macsó (and took possession of the Banate of Kucsó). Dušan Stephen openly pursued an anti-Hungarian policy, allying with the Bulgarian prince and Basarab, the Voivode of Wallachia.


SOUTHERN AND EASTERN CONQUESTS

During the forty years of Louis I's reign, most of the changes along Hungary's borders occurred in the south and east. In the south, a strengthened Serbia posed a challenge. The Serbian king of maternal, specifically Transylvanian Hungarian origin, Dušan Stephen, who bestowed upon himself the title of Tsar, had already occupied the Banates of Macsó and Kucsó under Charles Robert in 1339. It is likely that one of Louis' earliest foreign policy goals was to reclaim these territories located south of the Danube. In any case, these Banates were back in Hungarian hands by the end of 1342. Like his father, King Louis sought to rely on Bosnia against a strong Serbia and to counterbalance Serbia's dominance in the Balkans with a Bosnian alliance.

Well honestly, either way is fine. I hope the devs look into the question themselves too though.

That source is beyond questionable on the topic and should be discarded especially part around Dusan's "Transilvanian origin"
For Branichevo and Kuchevo were defacto incorporated into Kingdom of Serbia after death of Stefan Dragutin, King Milutin waged war against Charles Robert retaining Branichevo and Kuchevo, while Charles Robert took over Usora, Soli and Macva.

Engel Pál, Kristó Gyula or Kubinyi András, none of them are without their faults, and they can be mistaken too, but calling the collaborative work of three of the most respected near-contemporary Hungarian medievalist historians "beyond questionable" is a tad bit of a strong exclamation!

As with many things in the Balkans at this time, probably best regarded as a very flexible border that was hotly contested between the two (and knowing how often that Hungary and Serbia clashed, this seems rather supported by the evidence).

Basically the only hard border of Serbia that we know at this time is its border with the Byzantines and Ragusa. Everything else is shaky at best no matter which way you wish to cut.

I said that that the source is beyond questionable on the topic we are talking about, they make mistakes like "Dusan's Transilvanian origin" and for example Serbo-Hungarian war of 1354 is completely wrongly depicted in Kristo's work, instead of Lois attacking Dusan while Dusan was negotiating with the pope and Dusan defeating Lois in Macva, he depicted Lois forcing Dusan to withraw from Macva even tho Dusan was not in Macva when Lois invaded Serbia.

Hi,

I present my proposal for the division of Croatia and Bosnia. I have taken into account some of the suggestions of others, but there are also some of my own ideas, which I got from reading various sources. Slavonia and Syrmia have such borders that they can combine with Hungary's proposal.

Since I am not from these places, I also ask for suggestions and comments, especially for Bosnia.

The location of Ohrid looks a little confused in some maps. The lake and impassible mountain terrain make it look like there are tiny slivers which are separated from the main province and might be a separate province.

To aid the map's usability should we move the province border to run through lake Prespa? Or artificially widen the gap between the lake and the mountains?
 
Albania might even look better than our own proposals!

As it's already uploaded on this map, we might see it tomorrow/next week?

Nice improvements but it seems like the name Albania is still in use, it's not wrong but it'd make more sense to rename it to the duchy of Durazzo since the Angevins don't control anything else beside the city itself and Corfu(duke Charles and his father never used the title of king) also they may have been the officially recognized kings of Albania but there were other polities that claimed ownership of the region such as the house of Thopia(they titled themselves princes of Albania). Additionally Durazzo could be made a vassal of Naples from the start like Achea, technically they were officially indipendent, had their separate laws and since Charles father obtained the throne they distanced themsleves from Naples, but due to their weak position, blood ties to the other Angevin rulers, distance and the fact that Charles was himself a vassal of the king(he's also count of Gravina which is in Apulia) make more than enough sense to have the tag be a under Naples from the start.

Thopias claimed the title "Prince of Albania" only after the fall of the Duchy of Durazzo, if I understand correctly. They did maintain the title "Kingdom of Albania" at this date, if I'm not mistaken.
For vassalage, I'd only make them vassals of Naples if vassals of countries can have their own vassals in turn, which might not be the case; also, the County of Gravina being a vassal of Naples while also being in a Personal Union with Albania doesn't mean Albania is a vassal of Naples, in fact countries can be vassals of one country while their ruler is also a ruler of a country that isn't a vassal of that overlord

Charles di have the title of king of Albania but as far as I know he never used it, from a gameplay perspecrive I think it would be more fun to have Albania be a formable tag that one of the principalities can form if they fulfill the requirements(of course Durazzo should have cores one locatiom they used to rule), regarding the vassal thing you are right just because Charles was a vassal of Naples it doesn't mean that his domains in Albana were but again from a gameplay perspective(I don't think that Grabina should be a tag in game) and a practical/realistic one(like I said considering Charles weakening position and ties with the crown) it would make sense to have Durazzo as some kind of vassal of Naples
