Eight Provinces of Korea

During most of the Joseon dynasty, Korea was divided into eight provinces. The eight provinces' boundaries remained unchanged for about 480 years from 1413 to 1895, and formed a geographic paradigm that is still reflected today in the Korean Peninsula's administrative divisions, dialects, and regional distinctions. The names of all eight provinces are still preserved today, in one form or another. These eight historical provinces form both North and South Korea, and are not to be confused with the modern provinces that make up North Korea or South Korea.
