The Proto–Three Kingdoms period (or Samhan period) refers to the proto-historical period in the Korean Peninsula , after the fall of Gojoseon and before the maturation of Goguryeo , Baekje , and Silla into full-fledged kingdoms.

Goguryeo 's traditional founding date is 37 BC, but it was mentioned in Chinese records as early as 75 BC. China installed four commanderies in former Gojoseon territory, but three of them fell quickly to Korean resistance. Goguryeo gradually conquered and absorbed all its neighbors, and destroyed

Yang Pu's army of 50,000 sailed from Qi (present-day Shandong Province ) across the Bohai Sea towards Gojoseon, while Xun Zhi marched by land through Liaodong and headed towards Wanggeom , the capital of Gojoseon. One of Yang's commanders by the name of Duo took command of
60-515: A beaten pattern. Archaeological finds of the period are mainly from Nakrang and Goguryo in the north and Samhan in the south. Bronze and iron were used and iron made at shell midden sites on the southern coast. Artifacts typical of the Korean Bronze Dagger culture, some Han Chinese culture, and Northern Steppe cultures have been found together on archaeological sites in this region, indicating independent and extensive interactions by
80-446: A fine he was allowed to become a commoner. King Jun of Gojoseon Jun was the last king of Gija Joseon . He was succeeded by Wiman (Wei Man), whose usurpation of the throne began the dynasty of Wiman Joseon of Gojoseon . Wiman entered Gojoseon as a refugee, and submitted to King Jun.

100-476: A large number of troops and lead them ahead as a vanguard force. He suffered a disastrous defeat. As a result, Yang Pu had only 7,000 men with him when they reached the capital of Gojoseon, Wanggeom-seong . Seeing how small the enemy army was, King Ugeo marched out, defeating and routing Yang Pu's army. Yang Pu spent the next ten days rounding up the remnants of his army, which had fled into the nearby mountains. Meanwhile Xun Zhi failed to break Gojoseon's army west of
120-586: The Yalu River . When Emperor Wu received news of these defeats, he wished to reestablish peaceful relations between Han and Gojoseon.

On the return trip, She He killed Wi Jang (衛長降), an assistant who had been sent to escort him home. This angered King Ugeo, who sent troops into Han territory to kill She He. The direct pretext for war thus came when King Ugeo had
160-491: The Han envoy executed, which angered Emperor Wu considerably. The initiation of war may also have been brought by the desire to remove the possibility that Gojoseon would ally with the Xiongnu against the Han . Another reason may also have been the deteriorating relations between Han and Gojoseon, because Wiman Joseon had prevented trade between Han and polities such as Jinbeon (진번, 眞番). In 109 BCE, Emperor Wu launched

Examples of artifacts originating from

After a sudden attack by Xun Zhi, the high minister of Gojoseon secretly sent envoys to discuss terms of surrender with Yang Pu, however no final agreement
340-426: Was absorbed into the later Gaya confederacy , which in turn was annexed by Silla. Because of this continuity, most historians consider the Three Kingdoms to begin around the fall of Gojoseon, but the three did not dominate the peninsula as kingdoms until around 300. Important features of this period include the widespread production of iron artifacts for daily use and the introduction of grey earthenware pottery with
