Early Life and Background
Wang Kŏn was born on January 31, 877, in Songak (modern-day Kaesong) to Wang Ryung and Lady Han. He descended from a wealthy family of hojoks (local lords) who specialized in maritime trade with China. While later hagiographical accounts attempted to link his ancestry to the Tang dynasty emperors, modern historians identify his family as influential Goguryeo nobility who accumulated significant wealth and regional control over the Ryesong River area.
During the decline of the Silla kingdom, the northern regions became strongholds for Goguryeo refugees. This environment provided the foundation for Wang Kŏn's eventual rise to power.
Rise to Power under Kung Ye
Wang Kŏn began his military career serving under Kung Ye, a powerful rebel leader in the northwestern region. Recognizing Wang Kŏn's strategic brilliance and leadership, Kung Ye promoted him to general. Wang Kŏn gained widespread fame through successful campaigns, including a notable naval operation against Later Baekje at Keumsung (Naju) in 903.
Beyond his military success, Wang Kŏn became beloved by the public for his generosity and his efforts to assist those living in poverty under Silla rule, establishing a reputation for benevolence that would later support his claim to the throne.
The Founding of Goryeo
By 918, the rule of Kung Ye had become unstable. On the night of July 24, four high-ranking generals—Hong Yu, Pae Hyŏn-gyŏng, Sin Sung-gyŏm, and Pok Chigyŏm—conspired to overthrow Kung Ye and install Wang Kŏn as the new monarch. Following a successful coup, Wang Kŏn was crowned on July 25, 918, at Pojeong Hall in Cheorwon.
He renamed the kingdom Goryeo and, in 919, moved the capital to his hometown of Gaegyeong.

The War of the Later Three Kingdoms
The path to unification was fraught with conflict, primarily against Later Baekje. In 927, during the Battle of Gongsan, Taejo suffered a devastating defeat against the forces of Kyon Hwon. According to legend, General Sin Sung-gyŏm sacrificed himself by exchanging armor with the king, allowing Taejo to escape and hide in a cave on Apsan Mountain.
Despite this setback, Goryeo recovered. In 935, King Gyeongsun, the final monarch of Silla, recognized the inevitability of Goryeo's rise and surrendered his kingdom peacefully. Taejo accepted the surrender with grace, granting Gyeongsun the title of prince and integrating the Silla royal line into his own through marriage.
Final Victory and Unification
In 936, Taejo led his final campaign against Sin-gom of Later Baekje. Facing internal strife and military disadvantage, Sin-gom surrendered, effectively unifying the nation for the second time in history. Unlike the earlier unification by Silla in 668, Taejo's unification was more complete, as it integrated a wider array of peoples and territories.
Diplomacy and the Balhae Connection
Taejo viewed the fallen kingdom of Balhae as a "Relative Country" due to their shared Goguryeo roots. After the Khitans destroyed Balhae in 926, Taejo warmly welcomed the Balhae crown prince and the ruling class, granting them land and incorporating them into the Goryeo royal household.
This kinship fueled a deep animosity toward the Khitans. In 942, Taejo famously exiled Khitan envoys and allowed their gift camels to starve under a bridge as retribution for the destruction of Balhae. He explicitly warned his descendants in his "Ten Injunctions" to remain vigilant against the Khitans.
Legacy and Family
Taejo's unification created a single, unified state that persisted until 1948. His strategy of stability involved marrying the daughters of local leaders to secure loyalty across the peninsula. He had six queens and numerous consorts, fathering 25 sons and at least 10 daughters.
