The history of the Niuri spinning wheel
A mechanism which utilizes mechanical devices (particularly a wheel) for partially automating the spinning of thread appears to have been independently invented multiple times throughout history, and it's difficult to say exactly where it was developed first.
In Niur, an early predecessor of the spinning wheel, called a "disc-spindle" first appears in the archeological record around 4800 BCE, in Eastern Shard. These devices incorporated a ceramic or wooden disc around a special kind of spindle, that when angeled correctly into a simple frame or even a purpose built hole in the ground, could be used to spin thread more efficiently than earlier techniques. It was particularly useful for the spinning of mafaly fibers, as their relative brittleness (especially of the more ancient cultivars) meant it required a very slow and steady pace to avoid breakage when utilizing older spinning techniques.
In the late Classical period, disc-spindles spread out of Shard along Kaitian trading routes, and were used to a limited extent to spin native cotton and Ulu, although those spread by Kaitian traders exclusively were made from wood. The first designs that at all resemble a more modern spinning wheel appear in Kaitian texts dated to the very end of Classical period, around 1750 BCE. These early designs combined the disc-spindle and its frame, as well as altering the orientation of both, and enlarged the disc significantly. The disc still was rotated by hand, and larger devices likely required two people to operate. It was probably originally designed to spin Ulu, but it was quickly adopted and adapted by Shardian spinners for use with Mafaly.
After the Post-Classical collapse, the wheel was largely forgotten in most of Niur, with the exception of Eastern Shard, where it actually would grow to be the dominant means of spinning mafaly, completely displacing the disc-spindle. The technology would gradually develop over the next thousand years, replacing the disc with a spoked wheel, and again changing the orientation of the parts. Wheel-spun mafaly thread and cloth would become a major export for this region, and as the Martial period progressed it would become the primary source of sail cloth and thread for Eastern Niur.
The strategic importance of this resource contributed to the notoriously brutal, centuries long conquest of this region by the Nashajh, and in that process it was likely that some of the technological expertise was lost. At the same time, the conquest, coinciding with a rediscovery of old Kaitian texts that mentioned the device, allowed for the technology to disseminate throughout Niur, where it saw for the first time widespread usage, although almost exclusively for the purpose of spinning coarse thread for the manufacture of sails, primarily in military contexts.
The devastation at the close of the Martial period, and that wrought during the Niur war that followed, as well as the general decline in the size of the military caused the practice to gradually dwindle outside of the East Shardian cities, and in general the technology saw little advancement in the early Imperial Era.
It was only during the ascendency of the Yellow academy that the spinning wheel would see its next major evolution, as part of their periodic reforms the greater adoption of the spinning wheel was advocated and widely spread within Yellow academy institutions. These wheels were based on the most sophisticated East Shardian designs, and were further improved by the scholars and craftspeople within the Academy. These newer designs were rapidly adopted by the East Shardians themselves, who began to adapt the wheel to spinning other fibers outside of mafaly, and this, along with new innovations in weaving around the same time, seemed primed to make East Shard the dominant region for the manufacturing textiles for all of Niur.
However, the wealth afforded by these textiles proved only to further catalyze the wars that would destroy the East Shardian cities, as they were gradually conquered and destroyed by the independent inland peoples of Shard, forever ending Niuri control over Eastern Shard. The refugees from these war would settle throughout Niur, largely in areas where the Yellow Academy's rule had the most support. After the Yellow dynasty fell out of power, the support for these refugees would also decline, and most would assimilate to the local cultures.
The end of the Yellow dynasty also saw the disappearence of the spinning wheel throughout most of Niur. While it was still used for spinning sail cloth in part of Nirou (and more sparsely elsewhere), it would only really continue to be an actively developed technology in Nicre.
The Yellow Academy was widely supported in Nicre, even after they fell out of power, and many members of the academy fled to the safety of Nicre after its downfall, bringing along with them a great deal of accumulated knowledge. Many refugees from East Shard also relocated to Nicre, where they would bolster its craftsperson and artisan classes. The spinning wheel spread out of these communities, and it would continue to evolve in Nicre for the next several hundred years.
There for the first time spinning wheels emerged with hand cranks, and later treadles, and by the time of the Nicrean Renaissance these innovations had already transformed industry in Nicre and had begun to spread out to the rest of Niur.
Further advancements during this period, included greater degrees of automation and efficiency, and culminated in the development of machines capable of spinning multiple spools at once, and even early models of water wheel driven devices, unmatched in complexity until 18th century England.
While the technology for these machines never entirely disappeared, they required delicate and careful crafting to manufacture, and were unable to be massed produced. As Nicrean affluence declined amidst the Suri wars, little advancement was made in the development of these technologies, and this prevented them from extensively spreading beyond Nicre or even fully supplanting the more technologically simple spinning wheels even within Nicre.
Even so, by the end of the 11th century CE, the spinning wheel had become ubiquitous throughout Niur and has massively reduced the labor necessary to produce textiles, and the more technologically sophisticated machines that originated in Nicre would gradually begin to spread to the rest of Niur by around the 14th century, eventually becoming somewhat common by the beginning of the 17th century.
