Kinshū

Kinshū, officially the Republic of Kinshū, is a nation located in Bangju, within the cultural sphere of Sinju. Its population of 17,267,539 is spread across seventeen provinces covering its mainland area as well as its twenty islands. It is bordered by Tosanchi to the north, Basanreseri to the south, and the Eastern Sinju Sea to the west. Kinshū's capital, Sakaigawa, is located on Kazanjima, its largest island. The nation is largely rural, with most of its industrial centers located on the coast and outlying islands.

Modern-day Kinshū had been inhabited by nameless peoples since the Stone Age. Ancient Kinshūnese were a nomadic group of Fusenic peoples who migrated from Jungju and settled in the Kinshūnese Archipelago around 900 BCE. The early Kinshūnese were a maritime people focused almost exclusively on this archipelago and the coast of Kinshū, where they adopted indigenous fishing and agricultural techniques. By 60 BCE the first Kinshūnese states had developed, and they later became tributaries of Cheonje. These states were heavily influenced by Confucian and Buddhist thought. Following the fall of Cheonje in 876, Kinshū was reduced to a collection of petty kingdoms that engaged in near-constant warfare and piracy with each other and with neighboring kingdoms. Throughout the 10th and 11th centuries, the Kingdom of Iwasaki consolidated these states. By the late 12th century, a shift away from in the noble class led to the rise of a new social class, jizamurai, who banded together into leagues for mutual defense. Often followers of the teachings of Kenren, a monk, these leagues staged uprisings throughout the kingdom, eventually toppling provincial governors and instating new leaders, who were often abbots of local temples. In 1279, the monshu Kaneyo declared himself grand abbot of these provinces, breaking away from Iwasaki to form the Kingdom of Ikkokoku. The two kingdoms warred for several decades until Iwasaki was annexed.

From the outset, Ikkokoku was highly decentralized, with cities on the archipelago becoming more autonomous; it was during the 14th to 17th centuries that pirate states flourished in the region, preying on traders along the Yedal Road. Kaneyo's successor, Haruyo, adapted many of Kenren's teachings and passed numerous reforms that allowed Ikkoku to enjoy an era of relative stability, peace, and growth. By the late 19th century, the government had all but collapsed from heavy corruption and decentralization, leading to the Kinshūnese Civil War that resulted in victory for the warlord Tanesada Shigenori and the eradication of Jōdo Shinshū influences in the government. Shigenori's administration looked to Fusenese scholars and advisors for assistance, and began a rapid process of industrialization and imperialism. Kinshū's involvement in the Eulhae War gave it an economic boost, leading to it becoming a prominent regional industrial power throughout the 20th century.

Today, Kinshū is a rural nation whose economy relies on agriculture and heavy industry. It is famous for its language, which retains remarkable similarities to medieval Fusenese. The country is a member of the Council of Nations and the Sinju Union. Despite urges from the international community, Kinshū has struggled to embrace environmentally friendly business practices in the 21st century, and the nation suffers from heavy amounts of pollution.

Etymology
The kanji for Kinshū (葉秀, "beautiful celery) were first applied to the area by early Fusenic people who relied on the region's plentiful natural herb,, as a food source.

Prehistory
The earliest evidence of human activity in Kinshū dates to around 7000 BCE. Traces of stone tools found throughout Bangju indicate these early people groups migrated from present-day Wamu as far south as Shojin. While it is unclear how many of these people groups passed through Kinshū, there is archaeological evidence that suggests the aimuri culture had settled on the coast by 4,800 BCE. Small totems resembling various marine creatures and stone fishing tools have been found throughout the Kinshūnese Archipelago, suggesting these people were seafaring and established distinct clans throughout the islands. Unlike other early people groups in Bangju, the aimuri practiced marriage. In addition to the aimuri, archaeological evidence suggests that the wairigan and numaimi cultures--traditionally associated with Basanreseri also had settlements in present-day Kinshū.
