Carus vs Munmu of Silla

Carus launched a campaign against the Sarmatians along the Danube frontier. He defeated them in battle and forced them to sue for peace. This victory secured the Danube border and allowed him to turn his attention to the east.

Carus was proclaimed emperor by the legions in Pannonia after the assassination of Probus. He was a respected military commander and senator. His accession marked a brief period of stability and renewed military expansion.

Carus led a major invasion of the Sassanid Persian Empire. He advanced through Mesopotamia, capturing the cities of Seleucia and Ctesiphon, the Persian capital. This campaign restored Roman prestige after years of defeats by the Persians.

Carus died suddenly during his Persian campaign, reportedly struck by lightning in his tent. Some sources suggest he was assassinated. His death ended the campaign, and his son Numerian succeeded him, but the empire soon fell into further turmoil.

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.
