Qiniānxà Pànulàn (concept)
Qiniānxà Pànulàn, or 'Thousand Summer Rebellion', was an exceptionally devastating series of rebellions across western Kathun-Kai by both the philosopher-led Sēn'do Wa ('Esoteric' in Kathuni) peasant movement and Emperor Xu Yaon-Xu Wu's sisters, Xu Chuha and Xu Baohang who would later be referred to as the Linang bè Tāshǐng, or 'Two Angels', after being immortalized as folk-heroes.
The first seeds of rebellion were planted with the grave humiliation struck against Xu Yaon by the warlord Oarachad in the Gayhan Campaign, which caused a rapid deteoration in Xu Yaon's already shaky political standing and put his existence as reincarnation of the Dragon Empress (and first ruler of modern Kathun-Kai) Yao Ren Cai-Tiayang in doubt among the nobility and scholarly classes. While Xu Yaon desperately tried to rectify this by announcing a five year long period of festivities and feasts to celebrate 'his' victory over Oarachad, a famine caused by a poor growing season, the incompetence of the newly emplaced Governor Mai Chao in Iayan and damage to the farmlands from the Gayhan Campaign led to a terrible famine that would soon see thousands death.
With the peasantry furious that the Emperor feasted and celebrated while they starved, the long turbulent Sēn'do Wa philosophers fanned the flames and convinced the peasantry to join them in an uprising against Xu Yaon's rule, declaring that the Emperor could never be reincarnated from Yao Ren as they had preached for decades. The chaos led to an attempted palace coup by Xu Yaon's sisters along with their personal Fifth and Sixth Banners, and while it failed, they soon retreated north where they earned the loyalty of the states of Piyaon, Zhozhu and Wen who declared the sisters the true co-empresses of Kathun-Kai and joined their rebellion.
It took over twenty years for the Thousand Summer Rebellion to reach its end, bitter fighting leaving greatly damaging the west and north and the fighting only slowing when Xu Yaon was (allegedly) murdered by his personal sculptor. The two sisters attempted to then take their throne, but were betrayed by Governor Pu Yan of the State of Zhozhu, who had Xu Chuha murdered, with Xu Baohang being forced to go into hiding after being betrayed by her bribed soldiers. Xu Yaon's nephew Xu Giang, his favored and only sixteen years old, is said to have tricked the Fifth and Sixth Banners to believe that he had been declared Emperor and then marched in at their head. The panicked regents of Lóen Chaéon opened the gates to him, and he was quickly crowned. Following this, the year's harvest proved to be extremely bountiful, and this along with many public works programs calmed the turbulent peasantry and led to them naming him 'Shàlán de Lóen', or 'Kind Dragon'. The Thousand Summer Rebellion is said to have fully ended when Xu Giang offered his aunt his hand in marriage. Xu Baohong accepted, but upon entering within Lóen Chaéon, is said to have been 'murdered by a thousand servants with a thousand knives', at Xu Giang's order.
The Thousand Summer Rebellion would kill over 200000 Kathuni soldiers and citizens, and greatly changed Kathun-Kai's political organization between the general destruction and Xu Giang's reforms which attempted to head off similar events. The Rebellion would soon be followed by the Khayar Seldnii Darn, the western horselord Otached using the chaos to launch his great raid east. Most importantly to the historical record, Xu Giang's great fear at following his predecessors legacy was likely the greatest reasoning for his immediate and large response to Otached.
