The origins of the people today known as Korean are obscure. Research on later periods is easier because all Confucian societies, including Korea, has kept voluminous records; the prehistoric beginnings, however, are still murky, and archeological evidence is limited. One need not accept the claim of five thousand years of Korean art to recognize that there are at least two thousand years of a continuous situational, historical, and artistic tradition traceable and clearly labeled Korean, as well as earlier remains indicating that peoples have inhabited the Korean peninsula for three millennia.
