Wiman Joseon (194–108 BC) was part of the Gojoseon
period of ancient Korean history
. It began with Wiman
's seizure of the throne from Gojoseon
's King Jun
and ended with the death of King Ugeo
who was a grandson of Wiman. Apart from archaeological data, the main source on this period of Korean history comes from chapter 115 of Sima Qian
's ''Shiji'' (Records of the Grand Historian
). Wiman was asylum-seeker in Gojoseon, originally a military leader from the Kingdom of Yan
under the Han dynasty
According to Sima Qian
, Wiman was a general from the Yan state
of northeastern China after the collapse of China's Qin dynasty
, who submitted to Gojoseon's King Jun
. Jun accepted and appointed Wiman commander of the western border region of Gojoseon, which probably corresponds to the west of the present-day Liaoning
. Despite the generosity that King Jun had demonstrated, Wiman revolted and destroyed Gojoseon. In 194 BC, he established Wiman Joseon and decided to locate his capital in Wanggeom-seong
(왕검성, 王險城). Many Korean historians believe that the exact location of Wanggeom-seong was Yodong (요동) in Liaodong China.
In this period, Wiman Joseon expanded to control a vast territory and became strong economically by controlling trade between the Han Dynasty and the peoples of Manchuria
. Emperor Wu of Han
thought that Wiman Joseon increasingly threatened Han China, and Wiman Joseon would ally with the Xiongnu
Wiman's grandson, King Ugeo
(우거,右渠), allowed many exiles from Han dynasty
of China to live in Wiman Joseon. The number of Han grew, however, and King Ugeo prevented the Jin state
from communicating with the Han dynasty. As a result, in 109 BC, Wudi of China
invaded Wiman Joseon near the Luan River. After failing several times to defeat Wiman Joseon's armies, Han Wudi tried to convince the princes of Wiman Joseon to kill King Ugeo. The conspiracy failed and it led to the destruction of the Gojoseon kingdom. After the war, Wudi of Han dynasty sentenced two generals to death for failing to defeat Wiman Joseon.
After a year of battle, Wanggeom-seong was captured and Wiman Joseon was destroyed. Han dynasty established the Four Commanderies of Han
in the captured areas, which corresponds to the current area of Liaodong peninsula
and the northwestern Korean peninsula. The Commanderies eventually fell to the rising Goguryeo in 4th century AD.
Several nations were formed in its place. Among them was the Nangnang Nation. The Nangnang Nation must be differentiated from the Lelang
