Ryukyu Kingdom


The Ryukyu Kingdom was a kingdom in the Ryukyu Islands from 1429 to 1879. It was ruled as a tributary state of the Ming dynasty by the Ryukyuan monarchy, who unified Okinawa Island to end the Sanzan period, and subsequently extended the kingdom to the Amami Islands and Sakishima Islands. The Ryukyu Kingdom played a central role in the maritime trade networks of medieval East Asia and Southeast Asia despite its small size. The Ryukyu Kingdom became a vassal state of the Satsuma Domain of Japan after the invasion of Ryukyu in 1609 but retained de jure independence until it was transformed into the Ryukyu Domain by the Empire of Japan in 1872. The Ryukyu Domain was formally annexed by Japan in 1879 and reorganized as Okinawa Prefecture, and the Ryukyuan monarchy was integrated into the new Japanese nobility.

History

Origins of the Kingdom

In the 14th century small domains scattered on Okinawa Island were unified into three principalities: Hokuzan, Chūzan, and Nanzan. This was known as the Sanzan period period. Hokuzan, which constituted much of the northern half of the island, was the largest in terms of land area and military strength but was economically the weakest of the three. Nanzan constituted the southern portion of the island. Chūzan lay in the center of the island and was economically the strongest. Its political capital at Shuri, Nanzan was adjacent to the major port of Naha, and Kume-mura, the center of traditional Chinese education. These sites and Chūzan as a whole would continue to form the center of the Ryukyu Kingdom until its abolition.
Many Chinese people moved to Ryukyu to serve the government or to engage in business during this period. At the request of the Ryukyuan King, the Ming Chinese sent thirty-six Chinese families from Fujian to manage oceanic dealings in the kingdom in 1392, during the Hongwu Emperor's reign. Many Ryukyuan officials were descended from these Chinese immigrants, being born in China or having Chinese grandfathers. They assisted the Ryukyuans in advancing their technology and diplomatic relations. On 30 January 1406, the Yongle Emperor expressed horror when the Ryukyuans castrated some of their own children to become eunuchs to serve in the Ming imperial palace. Emperor Yongle said that the boys who were castrated were innocent and did not deserve castration, and he returned them to Ryukyu, and instructed the kingdom not to send eunuchs again.
These three principalities battled, and Chūzan emerged victorious. The Chūzan leaders were officially recognized by Ming dynasty China as the rightful kings over those of Nanzan and Hokuzan, thus lending great legitimacy to their claims. The ruler of Chūzan passed his throne to King Hashi; Hashi conquered Hokuzan in 1416 and Nanzan in 1429, uniting the island of Okinawa for the first time, and founded the first Shō dynasty. Hashi was granted the surname "Shō" by the Ming emperor in 1421, becoming known as Shō Hashi.
Shō Hashi adopted the Chinese hierarchical court system, built Shuri Castle and the town as his capital, and constructed Naha harbor. When in 1469 King Shō Toku, who was a grandson of Shō Hashi, died without a male heir, a palatine servant declared he was Toku's adopted son and gained Chinese investiture. This pretender, Shō En, began the Second Shō dynasty. Ryukyu's golden age occurred during the reign of Shō Shin, the second king of that dynasty, who reigned from 1478 to 1526.

Invasion of neighbouring islands and the Amami islands

In 1429, during the reign of King Shō Hashi, Ryukyu invaded Okinoerabu Island and Yoron Island. This was the first stage of Ryukyu's southward policy out of Okinawa island. In 1447, King Shō Shitatsu conquered Amami Oshima. In 1466, King Shō Toku attacked Kikai Island on two occasions. The fierce resistance of the islanders resulted in many casualties, but the island was finally placed under the control of the Kingdom of Ryukyu. King Shō Toku himself led 2,000 soldiers in large-scale operations but the cost of the war became a cause of domestic discontent. The Amami Islands became part of the Ryukyu Kingdom's territory from the Muromachi period onwards, along with the other Nansei Islands.
The Amami Islands traded with the Dazaifu, as mentioned ‘Aakumi Island’ in the Mokkan. During the Kamakura - Nanbokucho periods, Amami was under the Hojo Tokumune's property. Later Chikama-Shi was reorganised as stewards of the Satsuma Province, a territory of Shimazu clan. Chikama Tokiie Josho ind 14 April 1306 states that he gave “Kikaijima, Oshima ” etc. to his heir Sadayasu, “Erafu Island” to his second son Tsuneie, seven islands to his third son Kumayashamaru and “Tokushima” to his daughter Himekuma.
During this era, the Ryukyu kingdom expanded north and south and new territory provided a stable basis for trade in the kingdom thereafter.

Golden age of maritime trade

For nearly two hundred years the Ryukyu Kingdom would thrive as a key player in maritime trade with Southeast and East Asia. Central to the kingdom's maritime activities was the continuation of the tributary relationship with Ming dynasty China, begun by Chūzan in 1372, and enjoyed by the three Okinawan kingdoms which followed it. China provided ships for Ryukyu's maritime trade activities, allowed a limited number of Ryukyuans to study at the Imperial Academy in Beijing, and formally recognized the authority of the King of Chūzan, allowing the kingdom to trade formally at Ming ports. Ryukyuan ships, often provided by China, traded at ports throughout the region, which included, among others, China, Đại Việt, Japan, Java, Korea, Luzon, Malacca, Pattani, Palembang, Siam, and Sumatra.
Japanese products—silver, swords, fans, lacquerware, folding screens—and Chinese products—medicinal herbs, minted coins, glazed ceramics, brocades, textiles—were traded within the kingdom for Southeast Asian sappanwood, rhino horn, tin, sugar, iron, ambergris, Indian ivory, and Arabian frankincense. Altogether, 150 voyages between the kingdom and Southeast Asia on Ryukyuan ships were recorded in the Rekidai Hōan, an official record of diplomatic documents compiled by the kingdom, as having taken place between 1424 and the 1630s, with 61 of them bound for Siam, 10 for Malacca, 10 for Pattani, and 8 for Java, among others.
The Chinese policy of haijin, limiting trade with China to tributary states and those with formal authorization, along with the accompanying preferential treatment of the Ming Court towards Ryukyu, allowed the kingdom to flourish and prosper for roughly 150 years. In the late 16th century, however, the kingdom's commercial prosperity fell into decline. The rise of the wokou threat among other factors led to the gradual loss of Chinese preferential treatment; the kingdom also suffered from increased maritime competition from Portuguese traders.

Rebellion against the Shuri government Court and Centralization power

In 1493, Ryukyu and the “Japanese warships” were involved in a conflict in Amami and Ryukyu was victorious in the incident. In 1500, the Oyake Akahachi Rebellion broke out in Ishigaki Island, one of Yaeyama Islands. King Shō Shin deployed approximately 3,000 troops and 46 warships to conquer the region. In 1507, he invaded Kume Island, and in 1522, he suppressed the rebellion of Onikō in Yonaguni. In 1537 and 1571, he suppressed rebellions in the Amami region.
In 1509, as stated in stone tablet "Momourasoe-no-Kanmei", the so-called “sword hunt” was carried out, and all weapons possessed by the nobility called Samure and civilians were confiscated and stored in the royal armory under the strict control of the Shuri royal government. To suppress the rebellion of the ajis, he forced them to reside in the vicinity of Shuri Castle and effectively dismantled the military capabilities of their subordinate troops.
As Shuri royal government concentrated its forces in Naha, central region were poorly defended, where the Satsuma army landed.

Satsuma Clan's invasion and subordination

Around 1590, Toyotomi Hideyoshi asked the Ryukyu Kingdom to aid in his campaign to conquer Korea. If successful, Hideyoshi intended to then move against China. As the Ryukyu Kingdom was a tributary state of the Ming dynasty, the request was refused. The Tokugawa shogunate that emerged following Hideyoshi's fall authorized the Shimazu family—feudal lords of the Satsuma domain —to send an expeditionary force to conquer the Ryukyus. The subsequent invasion took place in 1609, but Satsuma still allowed the Ryukyu Kingdom to find itself in a period of "dual subordination" to Japan and China, wherein Ryukyuan tributary relations were maintained with both the Tokugawa shogunate and the Chinese court.
Occupation occurred fairly quickly, with some fierce fighting, and King Shō Nei was taken prisoner to Kagoshima and later to Edo. To avoid giving the Qing any reason for military action against Japan, the king was released two years later and the Ryukyu Kingdom regained a degree of autonomy. However, the Satsuma domain took back the control over some territory of the Ryukyu Kingdom, notably the Amami-Ōshima island group, which was incorporated into the Satsuma domain and remains a part of Kagoshima Prefecture, not Okinawa Prefecture.
The kingdom was described by Hayashi Shihei in Sangoku Tsūran Zusetsu, which was published in 1785.

Tributary relations

In 1655, tribute relations between Ryukyu and Qing dynasty were formally approved by the shogunate. This was seen to be justified, in part, because of the desire to avoid giving Qing any reason for military action against Japan.
Since Ming China prohibited trade with Japan, the Satsuma domain, with the blessing of the Tokugawa shogunate, used the trade relations of the kingdom to continue to maintain trade relations with China. Considering that Japan had previously severed ties with most European countries except the Dutch, such trade relations proved especially crucial to both the Tokugawa shogunate and Satsuma domain, which would use its power and influence, gained in this way, to help overthrow the shogunate in the 1860s.
The Ryukyuan king was a vassal of the Satsuma daimyō, after Shimazu's Ryukyu invasion in 1609, the Satsuma Clan established a governmental office's branch known as Zaibankaiya or Ufukaiya at Shuri in 1628, and became the base of Ryukyu domination for 250 years, until 1872. The Satsuma Domain's residents can be roughly compared to a European resident in a protectorate. However, the kingdom was not considered as part of any han : up until the formal annexation of the islands and abolition of the kingdom in 1879, the Ryukyus were not truly considered de jure part of Edo Japan. Though technically under the control of Satsuma, Ryukyu was given a great degree of autonomy, to best serve the interests of the Satsuma daimyō and those of the shogunate, in trading with China. Ryukyu was a tributary state of China, and since Japan had no formal diplomatic relations with China, it was essential that China not realize that Ryukyu was controlled by Japan. Thus, Satsuma—and the shogunate—was obliged to be mostly hands-off in terms of not visibly or forcibly occupying Ryukyu or controlling the policies and laws there. The situation benefited all three parties involved—the Ryukyu royal government, the Satsuma daimyō, and the shogunate—to make Ryukyu seem as much a distinctive and foreign country as possible. Japanese were prohibited from visiting Ryukyu without shogunal permission, and the Ryukyuans were forbidden from adopting Japanese names, clothes, or customs. They were even forbidden from divulging their knowledge of the Japanese language during their trips to Edo; the Shimazu family, daimyōs of Satsuma, gained great prestige by putting on a show of parading the King, officials, and other people of Ryukyu to and through Edo. As the only han to have a king and an entire kingdom as vassals, Satsuma gained significantly from Ryukyu's exoticness, reinforcing that it was an entirely separate kingdom.
According to statements by Qing imperial official Li Hongzhang in a meeting with Ulysses S. Grant, China had a special relationship with the island and the Ryukyu had paid tribute to China for hundreds of years, and the Chinese reserved certain trade rights for them in an amicable and beneficial relationship. Japan ordered tributary relations to end in 1875 after the tribute mission of 1874 was perceived as a show of submission to China.

Annexation by the Japanese Empire

In 1872, Emperor Meiji unilaterally declared that the kingdom was then Ryukyu Domain. At the same time, the appearance of independence was maintained for diplomatic reasons with Qing China until the Meiji government annexed the Ryukyu Kingdom when the islands were incorporated as Okinawa Prefecture on 27 March 1879. The Amami-Ōshima island group which had been integrated into Satsuma Domain became a part of Kagoshima Prefecture.
The last king of Ryukyu was forced to relocate to Tokyo, and was given a compensating kazoku rank as Marquis Shō Tai. Many royalist supporters fled to China. The king's death in 1901 diminished the historic connections with the former kingdom. With the abolition of the aristocracy after World War II, the Sho family continues to live in Tokyo.

Royal crest

The family crest of the Ryukyuan kings is called Mitsu-domoe and it is commonly used in Japan.
In Shintoism, Mitsu-domoe represents Emperor Ojin. King Shō Toku worshshipped Yahata and adapted the crest. He has also built the Asato Hachiman Shrine.
It is also said to be a balance of three forces, symbolizing the balance of Kitayama, Nakayama, and Nanzan.
