Korean History

Gojoseon

People began living on the Korean Peninsula and its surrounding areas from some 700,000 years ago. The Neolithic Age began some 8,000 years ago. Relics from that period can be found in areas throughout the Korean Peninsula, mostly in coastal areas and in areas near big rivers.
The Bronze Age began around 1,500 to 2,000 B.C. in present-day Mongolia and on the peninsula.

As this civilization began to form, numerous tribes appeared in the Lioaning region of Manchuria and in northwestern Korea. These tribes were ruled by leaders, whom Dangun, the legendary founder of the Korean people, later united to establish Gojoseon (2333 B.C.). The founding date is a testament to the longevity of Korea’s history. This heritage is also a source of pride that provides Koreans the strength to persevere in times of adversity.

Three Kingdoms and Gaya

Town-states gradually united into tribal leagues with complex political structures which eventually grew into kingdoms. Among various tribal leagues, Goguryeo (37 B.C.- A.D. 668), situated along the middle course of the Amnokgang (Yalu River), was the first to mature into a kingdom.
