A Political Force in the Upstream Area of the Geum River in the 5th and 6th Century and its Course Ju, Bo-don [Abstract] The history of Gaya which used to have little record available has been revealed significantly due to increase in archeological materials for past 20 years. As a result, it was confirmed that Daegaya which was the most powerful political force was developed into a dynasty straddled a certain area beyond simply the leading power among allied forces after the late 5th century. Clear evidences that show this fact are inscriptions of ``Great King`` and ``subordinate`` engraved on earthenware. Daegaya expanded its territory with Gogyeong as its political base to the west. All areas into Daegaya were divided according to their characteristics. There were areas under direct control, areas with local officials dispatched, areas under indirect control and the members of union. Through archeological discoveries, cultural influence of Daegaya was confirmed to be reached to the eastern Honam area beyond our previous general assumption. Currently, there are debates regarding what relations Daegaya had with these areas. For this, this author traced its characteristic through reference materials, archeological materials and all sorts of circumstances at that time. As a result, this author concluded that Daegaya had the eastern Honam area under its political control in a time of great tumult of expansion into Baekje or Geum River area. This issue should be examined and clarified more precisely in future to determine the political level of Daegaya.
