The first Koreans are believed to have migrated into Korea from northern Asia around 3000 B.C. These peoples lived in villages and survived by farming and hunting.
The Koreans practiced Shamanism, which is the belief that both living and non-living things contained powerful spirits. Priests known as shamans helped the people communicate with the spirits, and helped the people understand their will.
By the 100s B.C., Korea had been conquered by China. From 109 B.C. until 220 A.D., the Koreans would be under the control of the Chinese. During this time period they would be heavily influenced by the Chinese. However, they would also manage to maintain many elements of their own culture.
