Islamic countries are a mixed bag, some have Debt Slavery, some have Slave Trade, some have banned Slavery.Omg it's so amazing that diplomacy is near, I was dying to see it!
Just one question about slaves: I see proposed mechanics very well portrays laws and functioning of slaves in the new world. How about islamic world? Slavery was very widespread there, and slaves should perhaps be mostly treated as servants in wealthy houses.
Also, will Ottomans have slavery? In vic2 they had it abolished which I think isn't entirely historically accurate, as slave trade was present in Ottoman Empire at least till 50s, and slavery was functioning somehow in fact till the collapse of empire... Which slavery law category would Ottomans get?
There will not be an internal slave trade system, at least not at launch. It is something we really do want to add in, because as you say it is an important dynamic to consider when trying to fully deconstruct the economic beneficiaries and political support for the institution of slavery. But it's one thing to represent that there is a slave trade going on through moving people around the world in response to laws and economic demand, and a whole other quagmire to actually represent people with price tags on them - in an economics-focused game - in a way that doesn't trivialize the topic. So we might go there eventually if we can find a good way to represent it, but for the moment we've accepted not being able to model this.
The way this is modeled is via subject relationships, for example via Spain and Cuba. Slavery is outlawed in Spain but permitted in Cuba, which is a colonial subject of Spain.
"Farmers" in Victoria 3 are Pops who have an expertise in growing crops, caring for cattle, and running a farm. Pops who do manual labor on a farm, harvesting and such, are either considered Laborers or Peasants. Both of those can be replaced by Slaves in countries where this is allowed.
There is systemic fallout from banning Slavery for any country in which Landowners have gotten rich off it, and any country could potentially have a civil war around this issue. The American Civil War specifically has some more aspects to it, both in terms of flavor and mechanics. But a slavery-related civil war could happen anywhere or nowhere in a given playthrough.
In brief - and to also answer all the questions about "who would be enslaved if I instituted Slavery in my nation that started without it" - this is exactly how Slaves enter your country under Slave Trade, yes. Slaves only come into existence through Debt Slavery and the natural Pop Growth of Slaves under Slave Trade. If a country has no Slaves, and pass Slave Trade, they will start importing Slaves from countries with Debt Slavery.
They will likely remain Discriminated status on account of their heritage, and they will not have accumulated the same level of Qualifications as the rest of the Pops in the country while they were Slaves. So yes, they will almost certainly continue to be substantially worse off than non-discriminated Pops for a long time, especially until such time the country reforms their Discrimination laws.
No you are right! Debt Slavery can enslave anyone regardless of Discrimination status. Discrimination matters for the importation of Slaves under Slave Trade, which tends to lead to countries with Slave Trade having large quantities of Slaves that are also Discriminated.
It will anger all IGs that would have been angered by abolishing it through normal legislative means, which may very well lead to a civil war to bring back slavery (where the country that forced them to abolish it might have to intervene to keep slavery banned).
They're exclusive.
Buildings that has enough room to purchase Slaves will first try to draw from Slave populations local to the state. If none qualify, and the country has Slave Trade, they can cause a transfer of Slave populations from a country with Debt Slavery in a region where they have an Interest, which is something we'll talk about another time.
As mentioned a bit upstreams, plenty of countries start out with Slave Trade or Debt Slavery, far from just the US and Brazil.
You're not wrong! Our statement in the DD does apply mostly to countries where a sizeable part of the population are already Slaves, and where there is plenty of Arable Land on which to expand Plantations. If you already have a large workforce and you institute Slavery, you are correct that any newly imported Slaves would just occupy those menial jobs the domestic population would prefer not to do anyway.
Update! I have been corrected on this by the QA team, because it's changed in the current build: Cuba has Slave Trade, while Spain has Legacy Slavery. The only Slave State in Spain is Puerto Rico.
We're not yet ready to talk about Overlords' influence over their subjects' Laws. We'll return to this topic in the future.
If you just try to get rid of it with no preplanning, it tends to result in civil war since the law has powerful supporters, yes. The subtle way of getting rid of it is to gradually erode slavery proponents' political strength (absolute and/or proportional) through other means, like reforming your Bureaucracy, expanding the voting franchise, and creating well-paying urban jobs to promote liberalism, until their influence has waned enough that you can push through legislation without a civil war. You can also gradually dismantle it by going through Legacy Slavery first, since several smaller political shifts over time are easier to control than one quick big shift. Finally, you can wait until the stars are aligned - for example, a powerful Abolitionist Political Movement that helps push the law through, and/or an Abolitionist Interest Group Leader that can draw on the political strength of a group typically neutral to the issue of Slavery to shift the balance of power.
Different buildings will have different Slave Pop growth yes, but not by us tying it to the building type directly. Rather, it's tied to the economy of the building - if the building is doing very well and its non-Slave workers are satisfied with their wages, the building will under certain circumstances increase the Standard of Living target for its Slaves, within a range from Starving to Impoverished. Similarly, if a building is failing economically its Slaves will be the first to suffer for it. Which means that for example, if a country relies on huge Slave-operated monoculture Sugar or Fabric production, and then a foreign country cuts an Import Trade Route for Sugar or Fabric making the prices of those goods drop, the plantations will make up for it by decreasing their Slaves' Standard of Living and thereby growth (and also increase their Radicalism to boot).
