Pyongyang , North Korea

It is likely that the area of Pyongyang belonged to Wiman Joseon, the longest-lasting part of Gojoseon, which fell in the Gojoseon–Han War in 108 BC. Emperor Wu of the Han Dynasty ordered four commanderies set up, with Lelang Commandery in the center, and its capital established as "Pingrang" (平壤), or "Pyongyang". Several archaeological findings from the Later Eastern Han (25-220) periods in the Pyongyang area seems to suggest that Han forces later launched brief incursions around the area of Pyongyang.
