732년 渤海와 唐의 戰爭 과정 재검토

Abstract

For the war between Balhae and Tang Dynasty in 732, Silla is also involved and this has expanded to international war in South East Asia. This research reviewed data on the war and how it happened, processed, then made up. One of the reasons for the conflict between Balhae and Tang Dynasty is because of the issue in regards to Heuksu Magal race. In year 722, the head of the race came to Tang Dynasty to pay a tribute and Tang Dynasty granted the person with position called Jasa(刺史). In 725, one of the administrators in Tang Dynasty called Seotae suggested to install Heuksu army in the area and from year 726, the major region was considered as Heuksu administration and the minor area as regional administration. In 728, regional administrators were granted with the family name Lee and made them belong to Tang Dynasty, which has become a big threat to Balhae. As this is the case, King Wu of Balhae tried to suppress Heuksu Magal and his brother Damenyi exiled to Tang Dynasty after May 730. King Wu strongly asked for punishment of his brother but the King of Tang Dynasty refused this and even tried to punish Balhae. In regards to this, King Wu first attacked Dengzhou which will be the main war place if Tang attacked Balhae first. This is how the war started. There were four reason for Balhae to start the war. First, there was conflict between Heuksu Malgal and Damenyi between the two countries. Second, King Wu was unhappy about Tang Dynasty protecting him. Thirdly, it was the war over the kingdom between King Wu and his brother. The last reason was the international situation in the early 8th century. The war between Balhae and Tang lasted 3 years and the two countries exchanged ambassadors in 735.
