The formation and history of Nagdonggang river(洛東江) downstream culture

The coast of Nagdonggang river(洛東江) downstream is the place which river intersects with sea. Therefore an every kind resource was abundant and to settle down for the mankind was meeting remunerative terms. After the period of neolithic made initial nations on the various culture foundation. And each trade and redistribution of the initial nations were achieved through the main stream or tributary of the Nagdonggang river. The Nagdonggang river downstream have been compared with a delta area of a Nailgang river downstream to be the birthplace of ancient Egypt civilization. In the progress of ancient Korea history the Nagdonggang river downstream was a center role of the Gaya(伽倻) culture. And this area had the role as important point which accepted the high level ancient culture of China actively and deliver this to the inland. Also hard-fought battlefield of the Goryo(高麗) and Hubaegje(後百濟) were unfolded on the other side around the Nagdonggang river. Greater part was the southeast area of the Gyungsangdo(慶尙道). It is specificly the shore area to reach Jinju(晉州)-Busan(釜山)-Ulsan(蔚山) and Nagdonggang river middle-downstream of Yansan(梁山)-Miryang(密陽)-Chungdo(淸道). If had this area could become the victor, the importance which the Nagdonggang river's occupation at the time to quarrel of Husamgug(後三國) is very high of a strategic value. At the middle period of Goryo which the Sambyeolcho(三別抄) resisted, the Sambyeolcho army were tried to used a Nagdonggang river water traffic and diffuse the flag of anti-Gaegyoung(反開京) and anti-Mongolia (反蒙古) to the inland. That time Sambyeolcho contention was geting great hailing from the area's people. If Goryo government can not keep the Sambyeolcho contention properly, to reconciled with Mongolia were denied legitimacy and were the situation which the existence can be threatened. The mouth of Nagdonggang river coast were recognized as important spot to Sambyeolcho army and army of the Goryo government. After 14c' invasion of Japanese invaders, the Nagdonggang river downstream lost the importance role which is the starting point to carry in that time nation. And the area had the role about the alternating current with Japan only but the role could not be unfolded so that it was active. The politics economic role of mouth of Nagdonggang river coast shrank and could not get big concern from a center government. Also the area people and aboriginality force moved fast because the area came to be ruined. At period of Gaya the mouth of Nagdonggang river coast had the open personality which accept the culture and transmit with outside through the iron. But during go via Silla(新羅) and Goryo, this area could not bring the active development and change of his an area topology or culture because the area staid at far place from the center. Also this area brought about the seriousness at a foundation formation which can develope an area culture for ourselves because the domestic state was change and Japanese invaders invaded often. We can say that this area had limit to formed the downstream culture compare with Yeongnam(嶺南) area.
