The slavery system is closely related to agricultural culture. In China, the area south of the line connecting the Qinglin Mountains and the Why River receives more than １,０００ mm of annual rainfall. The north side is less than １０００mm, the south side has a rice cultivation culture, and the north side has a field cultivation culture.

Because field farming was simply inefficient, slaves were in high demand. Therefore, many slaves were used in the north. People who committed crimes were turned into slaves, and they were mass-produced by turning them into slaves in exchange for debt.

Because rice cultivation was introduced from southern China, Japan became a culture of rice cultivation, and field farming was introduced to the Korean Peninsula from northern China. Slaves were bought and sold as property as labor for field crops.

He was sold to five slaves for one cow. Rice was cultivated on the southern Korean peninsula, but it was not until the late Joseon period of the Joseon Dynasty that direct seeding was used.

Between the １５th and １７th centuries, slaves accounted for ３０-４０% of the Joseon Dynasty population. According to Ulsan household registration data from １６０９, ４７% were slaves. In １６０６, ６４% of Sancheong people in South Gyeongsang Province were slaves. The scale of slaves was ５０% in the Korean region.

The first attempt to eliminate racial discrimination internationally was a proposal made by a Japanese delegation at the Paris Conference of the League of Nations in １９１９.

This was not passed due to strong opposition from the United States. The first international effort to eliminate racial discrimination was the International Convention on the Elimination of All Forms of Racial Discrimination, published in １９６９.

Japan's slave system began in the early １０th century after the collapse of the Ritsuryo system, and the Edict to Abolish Slavery was issued in the middle of the Heian period. However, in reality, human trafficking was not eradicated, and the Edo Shogunate often issued prohibition orders in １６１２, １６１９, and １６８３, and cracked down on it severely.

Slavery was legally abolished in China by Aixinjueluo Puyi, the last emperor of the Qing Dynasty.

The Emancipation Proclamation was issued in １８６３, but it was not until the repeal of Jim Crow laws in １９６４ that racial discrimination became illegal in the United States.

On the Korean peninsula, the slave and white prison systems were legally abolished with the Gabo Reform of １８９４, but the actual situation did not change due to the failure of the Gashin Coup.

Kim Ok-gyun, who defected to Japan and was assassinated in Shanghai while aiming for Japanese-style modernization, argued that the feudal class system in Korean society was the root of inequality and the main cause of the country's corruption and decline.

Due to the annexation of Japan and South Korea and the introduction of the family register system, the need to list one's status on the family register was abolished. A surname was given to a slave who was not considered human and did not expect a surname. This allowed children to attend school.

The yangban groups opposed to the liberation of their status held violent demonstrations, but they were quickly put down by the Japanese government, which believed that educational opportunities should be provided to all regardless of their status.
