In the Ming Dynasty, Yanbian was governed by the Jianzhou Guard-district , and in the late Qing Dynasty the area was divided into the Yanji and Hunchun subprefectures.
In the 19th century, Korean immigrants migrated en masse from the Korean peninsula to China. After the foundation of the Republic of China, a second wave arrived. The population increase was caused by the Japanese invasion of that region. The Japanese were trying to use Korean immigration to diffuse the staying power of Chinese in that region. After the end of World War II, many Koreans did not go back to Korea, even though their country had been liberated . Instead, they joined the Chinese Civil War and were mobilized by both Chinese communists and the Chinese Nationalists. When the civil war was over, the new Chinese government gave Koreans their own autonomous region in 1952. Yanbian was upgraded to an ethnic autonomous prefecture in 1955.
In 1952, the Korean migrants composed some 60% of the local population, but by 2000 their share shrank to 32%. The Chinese authorities subsidize Korean language schools and publications, but also take measures to prevent an emergence of the Korean irredentism in the area. From the late 1990s the Koreans began to be assimilated into Chinese culture with increasing speed, often switching to daily use of Chinese and choosing to attend the Chinese language schools.
The name "Yanbian" was created in the 1920s, because it stretches on the boundary of three nations. It was also in the ''Yan''ji Border-affairs Public Bureau, where ''Yanji'' means ''Luck of the Stretch''. During the Manchukuo period, it was called Kan-do Province by the Japanese. The same characters when used as hanja in are pronounced and romanized as , however, the name Kil Im Song is more frequently used by Koreans to refer to the entire larger region of North East China.
