Munmu of Silla vs Sagara

King Munmu led Silla forces, in alliance with Tang China, to conquer Goguryeo. The fall of Goguryeo's capital, Pyongyang, ended the kingdom's 700-year history and completed the unification of the Korean Peninsula under Silla control.

Munmu ordered the construction of Gameunsa Temple near Gyeongju, dedicated to the protection of the unified kingdom. The temple was built with the hope of ensuring peace and prosperity, and it became a symbol of Silla's Buddhist faith and royal authority.

After the conquest of Goguryeo, Tang China attempted to establish control over the peninsula. Munmu led Silla forces in a war to expel the Tang armies, culminating in the Battle of Maeso. This victory secured Silla's independence and unified Korea under native rule.

Munmu formally established the Unified Silla kingdom, consolidating the former territories of Baekje, Goguryeo, and Silla under a single government. This unification ended the Three Kingdoms period and initiated a new era of Korean history.

Munmu died and was cremated, with his ashes scattered in the East Sea near Gyeongju. His burial at sea was a unique act, reflecting his wish to become a dragon protecting the kingdom. This practice was unprecedented in Korean royal tradition.

Sagara is said to have fathered 60,000 sons, who later became a famous army. This event is central to the story of the descent of the Ganges, as the sons were burned to ashes by the sage Kapila.

Sagara performed the horse sacrifice (ashvamedha) to assert his sovereignty. The horse was stolen by Indra, leading to a search that resulted in the discovery of the ocean, named Sagara after him.
