Sir Omega: Pretty much. The Vlachs have a history of being steady (albeit not powerful) allies. The Serbs from the Roman perspective act mainly like annoying trolls.
Stark: In hindsight, not following Nikolaios’ plan was a massive mistake on Helena’s part (I intended it to be that way). It was the last chance to stop the Ottomans from moving from ‘respectable threat’ to ‘SUPER-MAJOR threat’. Although on the other hand, the mentality that if you just raise enough tagmata you can declare yourself and become the legitimate Emperor is one that really needs to die. Ideally you could kill that and also prevent a mega-Ottoman. If you have to choose one, I’d personally go with the former even if it means a mega-Ottoman, but it’s a really tough choice and I can see why others might disagree. This will certainly be a hotly-debated question amongst Roman historians ITTL.
In regards to your question on money, here’s a copy of an answer I came up with earlier:
The Empire mints two silver coins, the miliaresion and stavraton valued in the Laskarid currency reforms at one-tenth and one-twentieth of a hyperpyron respectively. That was 300 years ago though and considering the influx of Mexican and Japanese silver (not to the extent of OTL but still there) I can see the silver coins losing some value relative to the hyperpyron, especially since maintaining a precise 10/20:1 value ratio probably wasn’t a high priority of the Roman government. So I’ll say that the value has dropped to a 12/24:1 value ratio. Going with that figure the miliaresion must have a silver content equal in value to .317 grams of gold (hyperpyron containing 3.8 grams of gold). According to Fernand Braudel in The Mediterranean and the Mediterranean World in the Age of Philip II in 1610 the average gold-silver value in Europe was 1:12. Therefore a miliaresion has .317x12 = 3.8 grams of silver.
Now assuming an annual budget of 16 million hyperpyra, that comes to 192 million miliaresions or 729.6 million grams of silver. That converts to just under 730 metric tons of silver. Based on the tables that puts the Empire somewhat behind late 17th/early 18th century France but well ahead of everyone else.
So the Roman Empire right now is comparable to France late in Louis XIV’s reign. The next major financial power would be the Triple Monarchy. I’d put their annual revenue around 450-500 metric tons of silver a year, slightly above that of Spain in 1600. The two of them are the financial superpowers of Europe; the only reason the Holy Roman Emperors avoided a major credit crunch is that they were able to squeeze the Triunes for bullion after beating them in the Rhine War.
Rui: There is a rough ministerial system already. Andronikos Sarantenos is the Roman equivalent of a British Foreign Secretary, and the Roman versions of Finance Minister and Justice Manager/Attorney General will be showing up in the next update.
As for provincial government, there’s some local autonomy. The larger cities have self-governing communes (Thessaloniki, Smyrna, Antioch) which have some taxation and legal authority over city citizens within the walls, although they do have senior Kephales looking over their shoulders. Peasant agricultural villages also have some leeway in administering internal affairs through councils of local elders provided they don’t violate Imperial law and they pay their taxes on time.
But the White Palace has absolutely no interest in devolving significate powers to the provinces. After all, if they think they can run themselves they might just get delusions of grandeur and try to break away from the Empire. Rhomania had a serious problem with that in the late 1100s and early 1200s. And democracy is very much a dirty word in government circles.
Duke of Nova Scotia: There’d be a coup justified by ‘the Emperor is bananas’ before he could get very far. A Senate which is more than just an irrelevant fancy social club…being able to vote…on legislation! Sounds like Venice…excuse me while I get my eyeball knife.
The Georgians are definitely working on rebuilding and upgrading their armies (in much the same way they reacted after getting hammered in the Orthodox War, rebuilding and then coming out swinging with a much improved army-that’s how they got most of the trans-Aras in the first place).
HanEmpire: I’d never heard of that show but now I really like it. There are a lot of Roman bureaucrats that would completely agree with this.
RogueTraderEnthusiast: The Idwaits’ main defense, besides logistical/geographic issues of course, is that their territory is mainly modern Sudan. It doesn’t yield nearly enough to justify the expense of taking it over. But if they started cozying up to the Marinids or Ottomans, they’d get put on Constantinople’s ‘must kill’ list really quick. If the Idwaits are paying attention, they know this. But if Rhomania or Ethiopia decide they want to have a go at the Idwaits, they have a ready-made casus belli. Per the treaties ending the war, the Idwait Malik-ate owes both the Empire and Ethiopia an annual tribute. Let’s just say the Malik is behind on his payments.
Emperor of Greater India: I agree. Rhomania could give the Vijayanagari all sorts of problems within cannon-range of the shore, seizing and/or sacking coastal settlements (although the Vijayanagari are building a fleet of their own so the Romans wouldn’t go unchallenged). But once they move inland beyond the range of offshore guns they have no chance. Even if somehow the Romans were able to ship every single tagma to India (which is not even remotely close to possible) and attempt a conquest of Vijayanagar, no bookie would give the Romans any better than 3 to 1 odds against.
I admit that Swati Kashmir has fallen off my radar so I’m undecided about what’s going on there.
Bengal is currently dominated by the Spanish Viceroyalty of Sutanuti, but it’s a very decentralized system with a bunch of petty Indian lords paying tribute to the Viceroy. To the west Oudh is the major power on the central Ganges and was never conquered by Iskandar although Ottoman troops did raid it. Any Vijayanagari envoy demanding tribute will have a short life expectancy. To the east Ayutthaya is a prosperous kingdom and sees a lot of business with the Triunes (it’s comparable to modern Myanmar is scope). The area in between Ayutthaya and the Viceroyalty is dominated by the Ahom although they don’t control the whole region.
The Christian Japanese have been occupied mainly with smacking down any Japanese who have a problem with Japan being Christian. It’s a full time job. But once that’s completed I view some kind of Imjin War as almost inevitable, since the Japanese Emperor will need to do something with all these soldiers running around. As for how alt-Imjin will go I can’t say, but unlike IOTL the Japanese will not have an artillery deficit vis-à-vis the Koreans. They are aware of the Wu, but from their point of view they’re too far to care about.
Arrix85: At this point the only power that could go toe-to-toe with the Vijayanagari on land is China. Only internal problems can bring them down at this point, although I will point that the Mughals were territorially at their height in 1707 and then everything proceeded to go very badly for them.
MarshalofMontival: I’m still fuzzy on timing, but I am planning on a TTL Sikh version at some point in the 1600s (and will include an alt-Ranjit Singh). On a side note, I wonder how the Anglo-Sikh Wars would’ve gone if they’d started whilst the Lion of the Punjab was still alive.
Lascaris:
Ottomans-So we are agreed, we attack India.
Rhomania-We are agreed.
Ottomans-Most excellent. [Deploys 100,000 to the Punjab. Vijayanagar counters with 250,000.] Uh, Rhomania, can you help me out here?
Rhomania-Sure thing. [Puts 9,000 men into Surat.]
Ottomans-Nine thousand, that’s it?!
Rhomania-Uh, yeah. Did you think I could put in more? Steamships won’t be a thing for at least another 150 years, dude.
Ottomans: I hate you. [Vijayanagar stabs them in the face.]
Rhomania. Mmmm, popcorn. [Munching sounds.]
AJustMonster: I concur with all of this. I’ll also add that there is no way a large Ottoman army could be sustained in India with supply lines going all the way back to Persia. So they’d have to base out of the Punjab. Any march deeper into India will have the rivers of the Punjab bisecting their supply lines. There’s all sorts of mischief the Ethiopians at Thatta could get up to.
I hope that covered everybody’s questions. Let me know if I missed any. And I must say that I’m really enjoying the detailed analysis and discussion. I’m honored.
