C. The Ruling System Is Restructured and the Independent Culture Is Cultivated
By strengthening his authority, King Taejong restored peace in the chaotic political environment. King Sejong hoped to further develop the state under a stabilized regime. King Sejong thus encouraged academic activities, placed men of high learning and virtue in office, and applied their opinions in governing the state. He encouraged agriculture by introducing new farming technologies, revamped the tax system, institutionalized the reduction of taxes during years of bad harvest. He thus exerted tremendous efforts in stabilizing the livelihood of the populace.
Meanwhile, King Sejong became concerned that many of his people were illiterate and thus faced difficulties in their lives. He became aware that the Chinese characters were too difficult to learn and use. He thus devised and promulgated Hunminjeongeum(hangul), an indigenous alphabet for the Korean people,which made it possible for anyone to readily learn and use it. He made the historic achievement of improving the lives of the people and promoting an independent national culture.
During the reign of King Seongjong, ‘Gyeonggukdaejeon’ , a code of laws governing the state, was established, which became the basic code for the Joseon kingdom. The civil service examination was expanded, schools were fostered and governance based on Neo-Confucianism was solidified. As seen here, Joseon restructured its systems and strengthened the framework for governance.
