Between 1416 and 1429, Chūzan chieftain [[Shō Hashi]] successfully unified the principalities into the [[Ryukyuan Kingdom]] (1429–1879) with the [[castle town]] [[Shuri, Okinawa|Shuri]] as royal capital, founded the [[List of monarchs of the Ryukyu Islands#The First Shō dynasty|First Shō dynasty]], and the island continued to prosper through maritime trade, especially tributary relations with the Ming dynasty.<ref name="MasamiIto2009"/> The period of [[Shō Shin]]'s (1477–1526) rule, descendant from the [[List of monarchs of the Ryukyu Islands#The First Shō dynasty|Second Shō dynasty]], is notable for peace and relative prosperity, peak in overseas trade, as well as expansion of the kingdom's firm control to [[Kikaijima]], [[Miyako-jima]] and [[Yaeyama Islands]] (1465–1524),{{sfn|Kerr|2000|p=115}} while during [[Shō Sei]] (1526–1555) to [[Amami Ōshima]] (1537).{{sfn|Hendrickx|2007|p=42}}

After the [[Kyūshū Campaign]] (1586–1587) by [[Toyotomi Hideyoshi]], his assistant [[Kamei Korenori]], who was interested in southern trade, wanted to be rewarded with the Ryukyu Islands. A paper [[Hand fan|fan]] found during the [[Japanese invasions of Korea (1592–98)]] mentioning a title "Kamei, Lord of Ryukyu", reveals that Hideyoshi at least nominally offered the post although he had no legitimate claim upon the islands. In 1591, Kamei ventured with a force to reclaim the islands, but the [[Shimazu clan]] stopped him as they guarded their special relationship with the Ryukyu kingdom. Hideyoshi was not very concerned about the quarrel because the invasion of Korea was more important in his mind.{{sfn|Kerr|2000|pp=151–152}} As the Ming's influence weakened due to disorder in China, Japanese established posts in Southeast Asia, and the Europeans (Spanish and Portuguese) arrived, the kingdom's overseas trade began to decline.{{sfn|Hendrickx|2007|p=43}}<ref name="MasamiIto2009"/>

In the early 17th century during the [[Tokugawa shogunate]] (1603–1867), the first ''[[shōgun]]'' [[Tokugawa Ieyasu]] intended to subject the kingdom to enable intermediary trade with China, and in 1603 ordered the Ryukyuan king to pay his respect to the shogunate. As the king did not react, with the instruction of the ''shōgun'', the [[Satsuma Domain|Satsuma feudal domain]] of the Shimazu clan in [[Kyūshū]] incorporated some of kingdom's territory during the 1609 [[Invasion of Ryukyu]]. They nominally let a certain level of autonomy and independence to the kingdom due to Ming's prohibition of trade with the shogunate, but forbade them trade with other countries except China. The Amami Islands became part of Shimazu's territory, taxes were imposed, making them subordinate in the relations between Japan and China.{{sfn|Kerr|2000}}{{sfn|Hendrickx|2007|pp=43–45}}{{sfn|Loo|2014|p=3}} Until the invasion, the Shimazu clan lords for four centuries had a vague title of the "Lords of the Twelve Southern Islands" or "Southern Islands", although initially meaning the near Kyushu islands, then covering all the Ryukyu Islands. Later in the 1870s this was used as a "justification" of Japan's sovereignty.{{sfn|Kerr|2000}} From 1609 the [[Ryukyuan missions to Edo]] started which lasted until 1850.{{sfn|Hendrickx|2007|p=45}}

During the rule of kings [[Shō Shitsu]] (1648–1668) and [[Shō Tei]] (1669–1709) i.e. [[sessei]] [[Shō Shōken]] (1666–1673) were recovered the internal social and economical stability with many laws about government organisation, and affairs like sugarcane production, and tax system with emphasis on agricultural production. The production was encouraged because Satsuma's annual tax deprived Ryukyu's internal resources. Although the production of sweet potatoes and sugar industry grew, the peasants were not allowed to enlarge their fields. The agricultural reforms especially continued under king [[Shō Kei]] (1713–1752) and his [[sanshikan]] advisor [[Sai On]] (1728–1752) whose ''Nomucho'' (Directory of Agricultural Affairs) from 1743 became the basis of the agricultural administration until the 19th century.{{sfn|Hendrickx|2007|pp=46–50}} In the Sakishima Islands great part of the tax was paid in textiles made of ramie.{{sfn|Hendrickx|2007|pp=51–52}} The relations with the [[Qing dynasty]] improved after their second mission when the first Ryukyuan official students were sent to China in 1688.{{sfn|Hendrickx|2007|pp=52–53}}

In the first half of the 19th century, French politicians like [[Jean-Baptiste Cécille]] unsuccessfully tried to conclude a French trade treaty with Ryukyu,{{sfn|Smits|2004|p=228}} with only a promise by Shuri government about the admission of Christian missionaries. However, due to extreme measures in teaching, [[Bernard Jean Bettelheim]]'s propagation of [[Protestantism]] between 1846–1854 was obscured by the government.{{sfn|Hendrickx|2007|pp=52–53}}
