In the late Goryeo Dynasty, with the deepening of Yuan's interference, Goryeo had virtually fallen into the status of a son-in-law nation to the Yuan Empire. Yuan's intervention extended beyond internal affairs to cultural impositions such as the queue (byeonbal) and Mongol attire, severely undermining Goryeo's sovereignty. However, in the mid-14th century, as the Yuan Empire began its decline due to the Red Turban Rebellions and internal power struggles, Goryeo found a golden opportunity to restore its independence. King Gongmin, who ascended the throne in 1351, recognized these shifts in international politics and harbored a strong will to break free from Yuan's domination and reclaim Goryeo's sovereignty. In 1356, King Gongmin initiated full-scale anti-Yuan independent reform policies. First, he ordered the abolition of the queue and Mongol attire, which were symbols of Yuan's rule and Goryeo's subjugation, aiming to restore national pride. He also abolished the Jeongdong Haengseong Imsunso, a Yuan administrative body that interfered in Goryeo's internal affairs, thereby reducing Yuan's influence. Concurrently, he boldly purged pro-Yuan figures such as Gi Cheol, Gwon Gyeom, and No Chaek, who had enjoyed power by clinging to the Yuan Dynasty, thereby strengthening royal authority and removing obstacles to reform. In the same year, King Gongmin dispatched generals Yu In-u and Yi Seong-gye to attack Ssangseongchonggwanbu, achieving the remarkable feat of recovering territory north of Cheollyeong. This was highly significant as it meant reclaiming Goryeo's historical lands that had been under Yuan's control for over a century. King Gongmin's anti-Yuan independent reforms were a crucial attempt to restore Goryeo's sovereignty and re-establish its national identity. They marked the beginning of the end of Yuan's interference and an effort to stabilize the nation's foundation by strengthening royal authority. Although the reforms did not fully succeed due to subsequent challenges such as the rise of Shin Don, limitations of the reforms, Wokou raids, and the second Red Turban invasion, King Gongmin's independent efforts greatly influenced the emerging literati (Shin Jin Sa Dae Bu) of late Goryeo, fostering a sense of national consciousness. This played a vital role in laying the ideological and political groundwork for the later Joseon Dynasty, making its historical significance immense.
