I. THE BEGINNING OF THE HISTORY OF KOREA
The history of Korea stretches back through the Paleolithic, Neolithic, Bronze and Iron Ages.
The ancestors of the Korean people lived on the Korean peninsula and in Manchuria.
The people of the Stone Age lived by hunting and fishing and began to develop primitive forms of agriculture. The people of the Bronze Age began to farm rice, and as they became engaged in full-scale farming, they developed a new society.
Kojoson, Korea's first nation-state, developed into a central force within East. In addition to Kojoson, many other nations existed on the Korean peninsula and in Manchuria during the Iron Age. By using iron farm implements, productivity and military strength increased, accelerating social development.
