The concept of the
Three Kingdoms of Korea refers to the three kingdoms of
Baekje (百濟),
Silla (新羅) and
Goguryeo (高句麗). The kingdom of Goguryeo is different from the Korean dynasty
Goryeo (高麗, 928–1392 AD). The Three Kingdoms period was defined as being from 57 BC to 668 AD (but there existed about 78 tribal states in the southern region of Korean peninsula and relatively big states like
Okjeo,
Buyeo, and
Dongye in its northern part and Manchuria).
