Background and rise to the throne

Upon Gogukcheon's death, his queen Lady U supported Sansang's claim and had him placed on the throne. She then became Sansang's queen. This indicates that the custom of Levirate marriage was still practiced in Goguryeo, but also demonstrated Lady U's power in court. Balgi, older brother to Sansang, led a rebel force attacking the capital, gaining military support of Chinese faction. Sansang had his younger brother Gyesu repel the attack, and Balgi committed suicide. Goguryeo was invaded by warlord Gongsun Kang in 204 after the older brother of the Goguryeo King Sansang of Goguryeo, Balgi, went to Gongsun Kang and requested 30,000 soldiers to invade Goguryeo so that Balgi could become king. Around this time, Kang established the Daifang Commandery by separating the southern half from the Lelang commandery. Although Goguryeo defeated the first invasion and killed Balgi, in 209, Kang invaded Goguryeo again seized some of its territory and weakened Goguryeo. Pressure from Liaodong forced Goguryeo to move their capital in the Hun River valley to the Yalu River valley near Hwando. In 217, he granted refuge to a thousand families from the Liaodong region.

Successor

In the eleventh lunar month of 208, the king chased a sacrificial boar to the village of Jutongchon, where he met a young woman and spent the day with her. The queen heard of this and sent royal forces, failing to kill her owing to her assertion that she conceived. The woman gave birth to a son and became a royal concubine. The son was made crown prince in 213 and later became King Dongcheon. Sansang died during 227, the 31st year of his reign, and was buried in Sansang-neung.
