Ni Taijo was now made king, to the great delight of the people. He sent an embassy to Nanking to notify the Ming emperor of affairs in the “outpost state,” to tender his loyal vassalage, to seek the imperial approval of his acts, and to beg his investiture as sovereign. This was graciously granted. The ancient name of Chō-sen was revived, and at the petitioner’s request conferred upon the country by the emperor, who profited by this occasion to enforce upon the Coreans his calendar and chronology—the reception of these being in itself alone tantamount to a sufficient declaration of fealty. Friendship being now fully established with the Mings, the king of Chō-sen sent a number of youths, sons of his nobles, to Nanking to study in the imperial Chinese college. The dynasty thus established is still the reigning family in Corea, though the direct line came to an end in 1864. The Coreans in their treaty with Japan, in 1876, dated the document according to the 484th year of Chō-sen, reckoning from the accession of Ni Taijo to the throne. One of the first acts of the new dynasty was to make a change in the location of the national capital. The new dynasty made choice of the city of Han Yang, situated on the Han River, about fifty miles from its mouth. The king enlarged the fortifications, enclosed the city with a wall of masonry of great extent, extending over the adjacent hills and valleys. On this wall was a rampart pierced with port-holes for archers and over the streams were built arches of stone. He organized the administrative system which, with slight modification, is still in force at the present time. The city being well situated, soon grew in extent, and hence became the seoul or capital (pronounced by the Chinese king, as in Nanking and Peking, and the Japanese kio, as in Kiōto and Tōkiō). He also re-divided the kingdom into eight dō or provinces. This division still maintains. The names, formed each of two Chinese characters joined to that of dō (circuit or province), and approximate meanings are given below. [6] With such names of bright omen, “the eight provinces” entered upon an era of peace and flourishing prosperity. The people found out that something more than a change of masters was meant by the removal of the capital to a more central situation. Vigorous reforms were carried out, and changes were made, not only in political administration, but in social life, and even in religion. In all these the influence of the China of the Ming emperors is most manifest.
