King Munmu

Silla forces under King Munmu (then Prince) allied with Tang China to defeat the Baekje army at Hwangsanbeol. This victory led to the fall of the Baekje kingdom, a key step toward unification.

Silla forces under King Munmu, in coordination with Tang China, defeated the Goguryeo army at the Salsu River. This victory resulted in the fall of Goguryeo, completing the unification of the Three Kingdoms under Silla.

After the fall of Goguryeo, Tang China attempted to establish control over the Korean peninsula. King Munmu led Silla forces in a war against Tang, successfully expelling Chinese forces and securing Silla's dominance over the unified territory.

King Munmu formally established the Unified Silla Kingdom after expelling Tang forces. This marked the first time the Korean peninsula was unified under a single indigenous ruler, creating a period of peace and cultural flourishing.
