[@Lucius Cypher] That's some great research that you did but I can't help but feel that it applies much more thoroughly to our world than it does to Remnant. You are right, we're lacking on a number of critical details regarding the Faunus/Human Wars but it seems to me that the lens your looking at it through doesn't exactly reflect Remnant all that well. The Faunus Rights War is also called the Faunus Rights Revolution which indicates that it wasn't about one kingdom or all kingdoms vs the faunus in another location. While there was large scale deportation to Menagerie it seems more likely that the faunus forces would have began in the kingdoms not dissimilar to what the White Fang does in present day. Attacks of terror, deprivation of resources, all aimed at making the human administration believe that it was less work to just give the faunus' the same rights as everyone else rather than keep oppressing them.

In that vein of thought the war probably didn't consist of traditional battles but more likely strikes on both sides, the faunus aiming where it would hurt the humans the most and the humans aiming at rebel bases. I'm not saying that there wouldn't have been faunus and humans fighting on the opposite side to their species, in all likelihood their would be faunus sympathizers who got rewards for betraying their people and then either corrupt or righteous humans who would help the faunus secretly either for money or because they thought it was the right thing to do. If the treatment of the less progressive minds shown on the show is any indication faunus were considered expendable to the point that butchering them on a large scale wouldn't have made any of the humans bat an eye. This isn't necessarily all true but if even some of the lager points are then it doesn't foster an environment where anyone would care to create a relief organization that more than just humans or how a faunus could have the kind of precision medicals skills your doctor has been implied to possess. The impression I got was that faunus were little better off than the blacks in slave period America. At that point it would have been a miracle for a black person to be literate let alone have any sort of trade experience outside of physical labor.

But with an upcoming episode dealing with Blake's return to Menagerie I'm hoping more details will be included.
