Jeju in 1374
A tragic incident that occurred under the influence of the Yuanming period

This paper provides a literary overview of the 'Tamna Kingdom' mentioned in the historical records of neighboring countries, including the Samguk Sagi, Goryeosa, Book of the Later Han, Records of the Three Kingdoms, Book of Wei, Dongyi Jeon, Nihon Shoki, and Tang Huiyao, and examines the period from the Neolithic Age to the Goryeo Dynasty.
Among them, the author focuses on the incident in 1374 when General Choi Young, the greatest general of the time, was sent to Jeju Island with 25,605 troops on 314 ships to suppress the so-called 'Mokho Rebellion'.
The Mokho Rebellion was an incident in which the Mongols, who had been dispatched to Jeju Island by the Yuan government and had become accustomed to the island while raising horses, resisted fiercely when Goryeo was under the control of the Mongol-founded Yuan Dynasty and operated Jeju Island as an autonomous Mongol territory called Tamna General Government Office. When the Yuan Dynasty collapsed and Goryeo attempted to regain control of Jeju Island, the Mongols who had become accustomed to the island resisted.


The reason why Choi Young's 25,000-strong army went to Jeju
Become a Goryeo soldier and set sail on a ship

Considering that the population of Jeju Island at the time was around 30,000, General Choi Young's force was an enormous force.
So why was General Choi Young's military force so formidable? During the reign of King Gongmin (reigned 1351–1374), the Ming Dynasty, which had driven out the Mongol Yuan Dynasty and secured China, sent a letter directly criticizing King Gongmin of Goryeo.
The text mentions that Goryeo was unable to stop foreign invaders from invading at will, and the Ming Dynasty boasts that it captured 13 Japanese ships this time, urging Goryeo to quickly deal with them before the Japanese pirates and Jeju Island's Mokho join forces to fight back.
Emperor Zhu Yuanzhang also severely punished a Ming officer who failed to properly stop the invading Japanese pirates by beheading him, and instead captured a Japanese ship and killed it as an example, saying that the sea was calm and that the Goryeo king should do the same.
King Gongmin was angry and ordered Choi Young to prepare a plan in 1374. Choi Young was furious and built 2,000 ships to catch the Japanese pirates.
Using the 314 ships he built at this time, Choi Young suppressed the Mokho Rebellion that broke out on Jeju Island.
At that time, one horse was worth three men.
There were a total of 10,000 horses being raised in Jeju, which was enough to warrant Choi Young sending an army of 25,000.

Accordingly, the author Hwang Yun became a Goryeo Dynasty person living in Anyang who was drafted into General Choi Young's unit and decided to go to Jeju Island by boat. He went to Mokpo, took a boat, stopped by Chuja Island, and arrived at Jeju Island.
Upon arriving in Jeju, I diligently searched for traces of General Choi Young and Mokho, collecting vivid accounts of what I saw, heard, and felt. In the process, I learned that the influence Mongolia had on Jeju Island still remains even after hundreds of years.

After completing his travels, the author returns home and writes a historical novel based on what he has explored and researched.
The title is “Gapin’s Change”.
So this book is also a very unique book in the form of a book within a book.
