In modern times, the region hosts South Korea's Gyeonggi Province and Incheon Metropolitan City, and North Korea's Kaesong Industrial Region, and Changpung, and Ch'ŏrwŏn counties.

Gyeonggi originally a frontier region to Kaesong, as well as the secondary capital Namgyeong (modern-day Seoul, South Korea).

Two years later, Taejo moved the capital south to Hanseong (modern-day Seoul).

Japanese Korea, or Chōsen (Kanji: 朝鮮), was administered from Keijō (JP: 京城; Korean: 경성), and was surrounded by Keiki-dō.

The provisional republic remained a sovereign, independent state for several days, until the United States and Soviet Union devised a plan to temporary partition Korea into two occupied zones, then reunify the peninsula once it was determined that the Koreans were fit to govern themselves.
