What happened
The historical Gojoseon state grew wealthy in its final centuries on iron tools introduced from China, which lifted agricultural output, and on trade goods including iron-rich grey stoneware. Around 300 BCE the neighboring Yan state attacked and weakened Gojoseon, and by the 2nd century BCE its territory passed to Wiman Joseon, founded when a Chinese refugee named Wiman, who had been given border-defense duties by King Jun, seized power for himself sometime between 194 and 180 BCE. Wiman Joseon lasted only a few generations. In 108 BCE the Han dynasty's Emperor Wu, eager for Korea's iron and salt, sent an army of 50,000 men and a 7,000-strong naval force, captured the capital Wanggeom, and divided northern Korea into four commanderies under direct Han administration, a occupation that lasted roughly four centuries.
Why it matters
The Han conquest ended Korea's first state but did not end Korean political life: refugees from the fallen Wiman Joseon carried its culture south into the peninsula, where it fed directly into the rival statelets that consolidated into the Three Kingdoms of Goguryeo, Baekje, and Silla. The name Joseon itself would resurface in 1392 as the name of Korea's last royal dynasty.
How we know
The fall of Gojoseon and the Han commanderies are recorded in Chinese historical annals of the period and corroborated by archaeological evidence from the Lelang commandery near Pyongyang, including Han-style administrative artifacts and burial goods.
