But weren't Maori (and especially Maori warriors) too militant to be useful slaves?
Hmm, not sure. I need to look into the history of Maori slavery in more detail - it was something used to a degree even in OTL.
Of course, there were many reasons for the revolution's success (weakening of French control due to the French revolution being very important one), but still - would it be reasonably safe to import whole enslaved iwis to *Queensland?
Regardless of anything else, I doubt that whole iwis would be enslaved and imported. Raids would be more typically along the lines of capturing a number of warriors (and civilians). So whatever slaves were brought to *Queensland would probably be from a mixture of iwis, and probably in smaller numbers.
On the other hand, importing only women and children would be pretty much safe bet, but women can't work as hard as men (especially during pregnancies and breastfeeding), while children need some time to grow into first-rate field hands.
Women were worked surprisingly hard in cotton plantations in OTL, and the way in which planters used child labour made an already morally abhorrent institution so much worse. I'm not so sure about the labour division for sugar plantations, but I'd still expect all slaves to be worked hard.
That is, there are two options for our prospective *Queensland planter - to get strong adult Maori male slaves (with their women and children, most probably) who can work hard and bring handsome profits to him almost immediately, but can also kill him and his family, or to get less dangerous Maori women and children only and to be content with long wait for profits. Of course, if Maori winners would kill off warriors of a defeated Maori iwi and sell their families, this dilemma would be solved without the planter's participation.
I do need to look into this in more detail, but I'd expect that slaves would consist of a mixture, both of genders and ages, but also mixtures of different iwi, or at least different hapu.
I know about blackbirding, but wasn't it limited to Melanesia in OTL because Indonesia/Dutch Indies was reasonably well-governed by the time of Queensland's sugar industry beginnings, so that going to the Dutch colonies to buy de-facto slaves would end with prison term at best and gallows at worst? Melanesia, on the other hand, was more or less independent (and defenseless) before late 19th-early 20th century, so Australians went blackbirding that way.
Blackbirding was broader than Queensland sugar planting. I'm not sure if it started in Peru or if both were practiced simultaneously, but it was conducted across a lot of the Pacific. I'm not sure whether Indonesia was avoided because of Dutch control, or whether it was just that Melanesia was closer.
Summing up all this slave trade and Maori conquests talk, the "Third World" looks set to become a strange, brutal but interesting place by late 17th - early 18th century, or so, with:
Oh my, yes.
Maori fleets raiding all over Oceania,
Check.
European (or Maori, or even Nangu) traders participating in the two-directional trade between *Queensland and Aotearoa (sugar and rum for slaves and flax),
Check. And also, probably, trade with places further south for various Aururian spices (myrtles etc) and maybe jeree/lemon tea, to sell on to places in Asia.
European planters, in their luxurious residences, trying to maximize their profits (and risking rebellions),
Quite. Although the planters may not be exclusively European.
slaves from Asia, Melanesia and Aotearoa suffering together under lash of (probably non-European) overseers and being made by their common experience into a new race, with its own pidgin language,
Could certainly happen. Although if the overseers speak a common language, that language will probably form the main basis for the pidgin language, as happened in various places in OTL.
different European countries trying to develop colonies or protectorates of their own (and destroy rival settlements), and being forced into alliances of convenience with Aururian or Aotearoan states (even when some of their partners eat human flesh or sacrifice some of their subjects).
Why, yes. Aururia (and Aotearoa) certainly looks like it will a playground of competing European states. A bit like the Caribbean was in OTL, but with native powers still surviving. Pirates, slavers, merchants, privateers, proxy wars, the whole works.
One can imagine three Maori chieftains meeting at the home of one of them, and recalling their lives - the first chieftain having made his fortune selling Polynesian slaves to Aururia, the second one being co-sponsor of his nephew's expedition to some Melanesian archipelago, and the last of them having been captured as a child by rivals who had raided his father's fortress, then sold to some slave trader, freed by his remaining kin in the Tasman Sea and returned to his iwi to grow up and bring vengeance to his father's killers. All three of them saw wider world beyond Aotearoa, speak at least one European language, and are good shots. One of them was baptized by Spanish missionaries some time ago (mostly out of hope to get better trade terms from Spain), another one accepted Pliri faith with sincere belief, while the third one remains "heathen". Confessional differences do not harm their friendship, though.
Hmm, I think I smell a future post coming up...
To counterbalance the Europeans, if the Aururians get decent naval capabilities, they could possibly ally with the Moġuls or Southeast Asia's Independent states, which could in turn weaken the European's grasp on the Indo-Pacific. Just an idea.
It's not impossible, but there would probably need to be a change in outlook from the Asian states. They don't seem to have been particularly interested in OTL. Of course, if Aururians or their offshoots are around and trading in force, then there might be some potential there.
The thing is, the Moguls were more than able to build strong navy on their own, they had money, timber and sailors for it (they lacked naval guns and gunners, but these might be bought/hired in Europe/Ottoman Empire). However, they never built it. They were just not interested, it seems.
The Moghuls, in particular, were quite a land-based power even at their height. Open to receiving trade, but not particularly interested in going out for it. Whether anything could provoke a change in outlook, I'm not sure.
Sounds like the congixie might have some company in the interesting hybrid cultures of this TL
Heh. You never know. Although the Nuttana have to come from somewhere.
