| At the beginning of the 13 th century,Mongolia was founded and began to invade and expand.After seven military conquests,the mongols forced Koryo to pay tribute.In order to protect the state and improve the relationship with the Mongol Yuan,the Koryo court decided to marry the Mongol Yuan dynasty.At the time of the change of the Mongolian khan position,then decided to accept Korea.With the stability of the regime and the strength of the state,the Yuan dynasty began to strengthen its control and interference in the government of Korea,and formed a special suzerain-vassal relationship.Under this special suzerain-vassal relationship,the Yuan dynasty continuously strengthened its control and domination over Korea,and was characterized by high intensity of internal interference and resource requisition.Under the strong intervention of the Yuan dynasty,the Koryo royal family was almost a puppet,which seriously infringed the national sovereignty and subjected to severe economic exploitation,leading to the continuous rise of anti-Yuan sentiment in Koryo.At the end of the Koryo dynasty,King Kongmin,with the ideal of rejuvenation,took advantage of the political turmoil and decline at the end of the Yuan dynasty to lead Koryo to carry out the political reform of regaining the royal power and strengthening the rejuvenation,in an effort to get rid of the control of the Yuan dynasty.As Koryo continued to advance along the established road,the invasion of the Red Scarf Army disrupted Koryo’s strategic steps of seeking self-renewal and independence,greatly damaged Koryo’s social economy,exhausted Koryo’s national strength,threw the political situation into chaos,and aborted its reform.Although the reform of King Kongmin was not successful,it left valuable experience and lessons.At the same time,it also makes China and Korea return to the traditional suician-vassal state relationship,which has a profound impact on the reconstruction of the geopolitical order in northeast Asia. |
