King Munmu vs Modu Chanyu

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.

Modu Chanyu unified the nomadic tribes of the Mongolian steppe into the Xiongnu Empire after killing his father, Touman. He established a centralized military and political structure, creating a powerful confederation that rivaled Han China.

Modu Chanyu besieged Emperor Gaozu of Han at Baideng (modern Datong, Shanxi) for seven days. The Han emperor was forced to negotiate a peace treaty, agreeing to pay tribute and send a princess for marriage, establishing Xiongnu dominance over northern China.

Modu Chanyu formalized the Heqin treaty with the Han Dynasty, which included annual tribute payments, marriage alliances, and the recognition of the Xiongnu as equals. This treaty maintained peace for decades and set a precedent for Han-Xiongnu relations.

Modu Chanyu expanded Xiongnu control westward, defeating the Yuezhi and other nomadic groups. He extended Xiongnu influence over the Tarim Basin and parts of Central Asia, controlling key trade routes and establishing a vast steppe empire.
