King Muyeol vs Marquis Wen of Wei

Muyeol became king of Silla, beginning a period of alliance with Tang China that would lead to the unification of the Korean Peninsula.

Muyeol secured a military alliance with the Tang dynasty of China, agreeing to jointly conquer Baekje and Goguryeo. This alliance was crucial for Silla's unification efforts.

Muyeol led Silla forces, in coordination with the Tang army, to conquer Baekje. The fall of Baekje was a major step toward the unification of the Korean Peninsula under Silla.

Muyeol died before the conquest of Goguryeo was completed. His son, Munmu, succeeded him and finished the unification process.

Marquis Wen of Wei appointed the Legalist reformer Li Kui as chancellor. Li Kui implemented the 'Book of Law' (Fajing), a comprehensive legal code that became a model for later Qin law, and promoted agricultural reforms to strengthen the state's economy and military.

Marquis Wen established an academy at the Wei court, attracting Confucian scholars such as Zixia, a disciple of Confucius. This patronage helped spread Confucian teachings in Wei and contributed to the cultural flourishing of the state during his reign.

Marquis Wen appointed the military strategist Wu Qi to command Wei's armies. Wu Qi reformed the army, introduced new tactics, and led successful campaigns against Qin, capturing the Hexi region and significantly expanding Wei's territory.

Wei forces under Wu Qi defeated a Qi army at Guiling, securing Wei's dominance over the central plains. This victory established Wei as the leading state during the early Warring States period.
