During the Joseon, which was founded after the Goryeo, King Taejo of Joseon set the capital in Hanyang, while restructuring Gyeonggi's area to include Gwangju, Suwon, Yeoju, and Anseong, along with the southeast region. Since the period of King Taejong and Sejong the Great, the Gyeonggi region has been very similar to the current administrative area of Gyeonggi-do.
