History of The Joseon Dynasty - Rise To Prominence

Rise To Prominence

By the late 14th century, the 400 year-old Goryeo Dynasty established by Wang Geon in 918 was tottering, its foundations collapsing from years of war and de facto occupation from the disintegrating Mongol Empire. The legitimacy of Goryeo itself was also becoming an increasingly disputed issue within the court, as the ruling house failed to not only govern the kingdom effectively, but was also supposedly tarnished by generations of forced intermarriage with the Yuan Dynasty and rivalry amongst the various family branches (even King U's mother was a known commoner, thus leading to rumors disputing his descent from King Gongmin). Within the kingdom, influential aristocrats, generals, and even prime ministers struggled for royal favor and domination of the court, resulting in deep division among various factors. With the ever-increasing number of raids conducted by Wokou and the invasions of the Red Turbans, those who came to dominate the royal court were the reformed-minded Sinjin aristocracy and the opposing Gwonmun aristocracy, as well as generals who could actually fight off the foreign threats; namely a talented general named Yi Seong-gye and his rival Choe Yeong.

Following the wake of the Ming Dynasty under the charismatic Zhu Yuanzhang (the Hongwu Emperor), the royal court in Goryeo split into two conflicting factions: the group led by General Yi (supporting the Ming Dynasty) and the camp led by General Choe (standing by the Yuan Dynasty). When a Ming messenger came to Goryeo in 1388 (the 14th year of King U) to demand the return of a significant portion of Goryeo’s northern territory, General Choe seized the chance to argue for the invasion of the Liaodong Peninsula (Goryeo claimed to be the successor of the ancient kingdom of Goguryeo; as such, restoring Manchuria as part of Korean territory was part of its foreign policy throughout its history). A staunchly opposed Yi was chosen to lead the invasion; however, at Wuihwa Island on the Yalu River, he revolted and swept back to Gaegyeong (modern-day Gaeseong and the capital of Goryeo), proceeding to eliminate General Choe and his followers and initiating a coup d'état, overthrowing King U in favor of his son, King Chang (1388). He later killed King U and his son after a failed restoration and forcibly placed a royal named Yo on the throne (he became King Gongyang). After indirectly enforcing his grasp on the royal court through the puppet king, Yi then proceeded to ally himself with the Sinjin aristocracy such as Jeong Do-jeon and Jo Jun. One of his first acts as the de facto generalissimo of Goryeo was to pass the Gwajeon Law, which effectively confiscated land from the land-wealthy and generally conservative Gwonmun aristocrats and redistributed it among Yi's supporters in the Sinjin camp. In 1392 (the 4th year of King Gongyang), Yi's fifth son, Yi Bang-won, after failing to win over a noteworthy aristocrat named Jeong Mong-ju, a supporter of the old dynasty, to swear allegiance to the new reign, had the noble killed by the five assassins including Jo Yeong-gyu at Seonjuk Bridge near Gaegyeong, eliminating a key figure in the opposition to Yi Seonggye's rule. That same year, Yi dethroned King Gongyang, exiled him to Wonju, and ascended the throne. The Goryeo Dynasty had come to an end after almost 500 years of rule.
