37 B.C to 668 A.D
Korea began as Three Seperate Kingdoms
The three kingdoms in Korea were named Goguryeo, Baekje, and Silla.
The Three Kingdoms period in Korea began in the 4th century when three rival states - Goguryeo, Baekje, and Silla - emerged on the Korean Peninsula. They vied for power and territory until Silla ultimately unified the peninsula in the 7th century. Factors such as geography, internal strife, and competition for resources contributed to the formation of the Three Kingdoms.
It should still be "Tale of the Three Kingdoms" It is Chinese, but it was translated to Korean so long ago, it almost seems Korean. Don't be fooled the three kingdoms are not the Korean three kingdoms.
Buddhism and Confucianism
Confucianism and Buddhism
One of the main kingdoms of Korea that did not develop after colonization by the Chinese Han was the Unified Silla kingdom. The other three main kingdoms that emerged during this period were Goguryeo, Baekje, and Gaya.
The Three Kingdoms of Korea (Goguryeo, Baekje and Silla) existed from 57 AD until Silla's triumph over Goguryeo in 668. This marked the transition to the North and South States period of Unified Silla in the South and Balhae in the North.
Buddhism and Confucianism
The two belief systems adopted by the three kingdoms in 4th century AD Korea were Buddhism and Daoism. Both belief systems influenced Korean culture, philosophy, and art during this period.
