Now that we're in a bit of a down time moment with the vote being settled, I wanted to talk about The Future. Specifically, on how Eretria and the Epulian League can continue to grow.
Currently, our most obvious problem is an acute shortage of cash. We're currently running consistent deficits, primarily due to constructing the Great Harbour. When we finish our naval expansion, however, we're going to be in a seriously tight place; we won't be able to afford to build any more Great Works as we don't have the spare 100 talents/year in our budget.
We need to increase our revenues.
The question is: how to do it? The obvious answer is trade. After the Great Harbour finishes we're going to automatically get two more trade routes and open ourselves up for 19 more. If we can fill all of those, that's equal to
118 talents worth of income at our current Tariff Efficiency level (assuming only Staple trade routes). If we can create some Luxury Trade Routes (e.g. Murax Dye, Amber, Glass, Perfumes, Pottery), then our revenues go up considerably; each Luxury trade route is worth roughly two thirds more than a staple route.
We can also increase our incomes by increasing our current level of taxation. Really the only way we can increase this, however, is by directly increasing Eretria's population. It's nice because we do get a roughly 3-5% boost in Taxation income each Census as population increases, but it's limited. There's not much we can do to actively
increase the growth of taxation. Given how the Metics are already straining on the tax burden we inflicted on them, it's likely taxation is going to shrink in the future. The citizens are not going to easily vote to raise taxes on themselves outside of exigent circumstances.
A third possible income source is tribute. Currently, we make 20.3 Talents from both the League and the Peuketti. With us fully subjugating the Messapii this turn, that'll rise to 30.6. This isn't something we can really raise easily; we could always make a User Motion to increase the level of tribute we demand, but that's going to cause unrest. One of our current greatest strengths is that our vassals don't want to dethrone us at the current moment. The Delian League is very much more hassle than it's worth for Athenai at the moment since they're constantly putting down rebellions. We don't want to end up in those shoes.
What we
can do, however, is subjugate the Danui. It's going to be expensive up front, but they're likely to pay about as much in Tribute as the Messapii and Peuketii: ~10.5 talents. Once they're subjugated, they'll
also give us an Overland Trade route
and access to Lake Salpai, one of the best locations for saltworks in the Mediterranean. It's hard to say how much Lake Salpai is worth, but it's important to note that many empires built themselves on the salt trade: Mali, Rome, China, Venice, etc. Lake Salpai is also a significant enough saltworks that it can be expanded and maintain relevance even with truly industrial levels of production.
This is something we'll do eventually, but at the moment, I'm a bit put off by the required initial costs of actually subjugating them. Given how we'd be able to call on the Epulian League, Peuketti, and Messapii, we wouldn't have to put forward too much troops ourselves and can defray costs that way. Just the League and our vassals alone would be an army of ~6,000 and that's significantly more than the Danui are likely to be able to muster.
Trade is easier, less risky and costly. In order to trade, however, we need to focus on the different groups we can trade with in the Adriatic and the colonies we can found. As I see it, we have five main possible trade partners: Enteoi/Histri, Northern Etruscans, Middle Illyria. Southern Illyria, Iapyges Tribes.
Breaking things down, these are the trade goods we could find in each region:
Enteoi/Histri
Imports (Staple): Agriculture products
Imports (Luxury): Pottery
Exports (Staple): Iron (several significant sources)
Exports (Luxury): Gold, Silver, Amber
Possible future trade goods: Cloth, Zinc
Northern Etruscans
Imports (Staple): Wood, Lamp oil
Imports (Luxury): Pottery, Gold, Glass, Ivory, Slaves, Perfume
Exports (Staple): Agriculture products, Timber, Pig iron
Exports (Luxury): Linen, Pottery, Manufactured goods (bronze, gold, ivory)
Possible future trade goods: Salt (from Venice's salt marshes), Zinc
Middle Illyrians (Dalmate, Darosai, Plaerai, Ardiaei, Labeates)
Imports (Staple): Agriculture products
Imports (Luxury): Pottery, Metalwork*
Exports (Staple): Slaves, Timber
Exports (Luxury): Silver
Possible future trade goods: Iron, Murex purple, Gold, Cloth
*Middle Illyria's metalworking is noted to be relatively poor compared their neighbours, both to the north and to the south. The only area they're noted not to be deficient is with weaponry.
Southern Illyrians (Parthini, Abri, Epirotes, Dassarate, Enchelae)
Imports (Staple): Agriculture products
Imports (Luxury): Pottery
Exports (Staple): Iron, Timber, Asphalt (waterproof caulk), Slaves
Exports (Luxury): Silver*
Possible future trade goods: Cloth
*Southern Illyria was a major producer of silver until about the 5th century BCE, but it's going to be making a comeback around this time in-game. Two new cities, Damastion and Daparria have been founded and are major centers for silver production.
Iapyges Tribes (Messapii, Peuketti, Dauni)
Imports (Staple): Agriculture products, all metals
Imports (Luxury): Pottery
Exports (Staple): Cattle, Agriculture products
Exports (Luxury): None
Possible future trade goods: Salt, Cheese
(Agriculture products include: wine, olive oil, grain)
Possible future trade goods require increased development, both in terms of increased trade ties, but also in terms of population and colonization.
With all of this in mind, I want to propose that we try and seek monopolies in Salt, Cloth, Glass, and Slaves.
Salt is something that is relatively hard to procure within our region and it's something everyone wants. If we can secure Lake Salpai and Venice's salt marshes, we'll have the two main production regions fully within our grasp. Given that we're already looking to establish an amber monopoly, pushing for a salt monopoly makes good sense as well. We're already going to secure an amber monopoly by establishing not!Venice, so why not seek to use their salt resources there as well.
Cloth is something I see becoming increasingly valuable as Sikelia, Hellas, Magna Gracia, and Cathage continue to urbanize. Roughly 95% of the effort of making clothing is in spinning raw wool into cloth and it's a relatively low-bulk good so it becomes a potent store of value. Clothing is useless without standardized sizing and unspun yarn is too bulky to transport; cloth is at just the right point to export.
The cloth industry formed the backbone of England and the Low Countries economy, making both regions incredibly wealthy. We can do the same thing with Illyria; most of the tribes there are still semi-settled with many still being herdsmen for cattle and sheep. They want to purchase goods from us like wine and olive oil, but don't have a good way to pay for it. By encouraging them to come down to our colonies and shear their sheep (similar to the cattle drive of the Iapyges), we can trade with them in that way. The colonies can spin the raw wool into cloth and we then export that to the urbanized regions south of us.
The Dalmate are also known for being poor metal smiths, but excellent shepherds. We can trade manufactured goods in turn for wool, hopefully boosting an internal manufacturing industry in Eretria itself. We'll need to negotiate with them, but we can colonize around Split to get the industry started.
As pointed out by
@The Sandman, the area around Brention is one of the few places in the Mediterranean that is suitable to produce good glass, along with Sikelia and Krete. By importing people with Demos Drakonia's colonialism policy, we can jump start our own industry; Venice held onto their secrets for the better part of a thousand years and it made them fantastically wealthy. Glass is one of the few things that is extremely difficult to manufacture and can't be easily replicated.
Slaves is something I want to make a monopoly only so that the Epulian League controls and restricts slavery. States that export slaves slowly rot from the inside out as each individual slaver fights with each other to get an advantage so they can be the seller and not the sold. If we want Illyria to actual begin to congeal as a region and become a large-scale trade partner, slavery is going to have to be limited.
Right now, the Greek demand for slaves is likely being fulfilled by Sikelia, but it's not a sustainable source of cheap slaves. Eventually, the Sikels and Sikani are going to be wiped out and their land taken. At that point, there's going to be no one left who can be enslaved and the current boom is going to collapse. At that point, it's going to look extremely tempting for slavers to look elsewhere to try and find somewhere they can continue their trade. If we don't lock down the Adriatic slave trade, they're going to invite themselves in. I'm much more inclined to let them try and go after (read: choke on) the native Italians for their slaving needs.
In general, if we want to make money from trade, we're in a good position to do so as soon as the Great Harbour finishes. We'll need to continue colonization and accept Demos Drakonia's immigration policy if we want to really break into trade and manufacturing as revenue sources.
With all of the above thoughts in mind on trade, I've gone looking for possible sites for new colonies. This isn't exhaustive, given the relatively small size of Greek
poleis, we could likely fit far more colonies in the Adriatic. The ones I'm proposing are the 'top of the lot' so to say. Italicized options are, I believe, first rate choices. All locations have modern names so you can find them on Google Maps if you want to look.
