Lelang Commandery
Korean mythology asserts that Pyongyang was founded in 1122 BC on the site of the capital of the legendary king Dangun. Wanggeom-seong, which was in the location of Pyongyang, became the capital of Gojoseon from 194 to 108 BC. It fell in the Han conquest of Gojoseon in 108 BC. Emperor Wu of Han ordered four commanderies be set up, with Lelang Commandery in the center and its capital established as "Joseon" (朝鮮縣, 조선현) at the location of Pyongyang. Several archaeological findings from the later, Eastern Han (20–220 AD) period in the Pyeongyang area seems to suggest that Han forces later launched brief incursions around these parts.
