I will have to hunt down the article regarding new immigration to the republic increasing, it could be this surge is from non-freed slaves and then it would stand to reason they didn't get the support of the social system. The actual emancipated are cared for but it seems everyone else fell by the wayside at least in some instances. In the case of the adonis medical articles, they are immigrants from the federation, which saw more Matari leave it for the republic after the one day war and has presumably had a net migration to the republic since.
other volunteers working in the Republic since early YC110, when 'transit camps' were set up by the government on major Minmatar planets to temporarily accommodate increasing numbers of Minmatar arriving from the Gallente Federation.
Keep in mind also that at this point the republic effectively had no government. Just the remains of what karin left and the sanmatar.
the articles you linked seem to all point not to the emancipated, it was prior to the majority of emancipated being transported by the SoE, i.e. they are normal immigrants in this case from the great wildlands or the federation. I guess this is the immigration waves post-shakor. It is a shame we never got demographics PRIOR so we could truly see how many thukker migrated.
According to the spokesman the official statuses of the Thukker, Starkmanir and Nefantar tribes have been the main stumbling blocks on the path to that goal, presenting a number of issues which Shakor had been hoping to resolve before making an announcement. Increasing political pressure and domestic strain stemming from the rising population are understood to have forced Sanmatar Shakor's hand, leading to today's parliamentary address.
All these groups are post-one day war and pre-emancipation act. I am guessing the infrastructure just was not in place and the remains of the first republic just were not up to the task.
Most of the Nefantar and Thukker, overwhelmingly most, were not slaves. The Starkmanir being included again is odd to me but I suppose it just points to the "protected status" being more of an ambition, at least until the Tribal Order got on its feet.
Also the religious persecution in the Republic I think is too downplayed by a lot of people, ..including myself. They do accept it but there have been more than one instance of violent crime and discrimination against those who keep their faith.
There is another article too somewhere about how Tribal culture and tradition is failing to launch in a way because of how much of it was destroyed, apathy among Matari, and the influence of the imperial rite and its hybrids.
Sorry, I wrote this over the entire day of and on so it is really scatterbrained. many sorries.
