The province's name literally means "area within a 500-li (200-km) radius" (gi; 畿) of the "capital" (Gyeong; 京), referring to the royal capital Hanseong (modern-day Seoul). The regional name "Gijeon" is obsolete. The 20th-century term "Sudogwon" ("Capital Region") is used today to denote the Seoul-Incheon conurbation and that part of Gyeonggi Province that forms part of the same built-up, urban area.
