Jiang Ziya vs Sima Yi

Jiang Ziya served as a key advisor to King Wen and later King Wu of Zhou. He provided strategic counsel on military campaigns, governance, and the consolidation of Zhou power against the Shang.

Jiang Ziya served as chief strategist for King Wu of Zhou at the Battle of Muye. The Zhou forces defeated the Shang dynasty army, leading to the fall of King Zhou of Shang and the establishment of the Zhou dynasty.

King Wu of Zhou enfeoffed Jiang Ziya as the Duke of Qi, granting him the territory of Qi in present-day Shandong. Jiang Ziya established the Qi state, which became a major power during the Spring and Autumn period.

Jiang Ziya implemented administrative and economic reforms in Qi, including land distribution and tax policies. He promoted agriculture, trade, and salt production, laying the foundation for Qi's prosperity.

Sima Yi led the Cao Wei forces to defeat the Shu Han army at Jieting, forcing Zhuge Liang to retreat. This victory prevented Shu from capturing the Chang'an region and secured Wei's western border.

Sima Yi successfully defended the city of Hefei against an Eastern Wu invasion led by Sun Quan. He repelled the Wu forces, maintaining Wei control over the Huai River region.

Sima Yi staged a coup against the regent Cao Shuang at the Gaoping Tombs. He seized control of the Cao Wei government, executing Cao Shuang and his faction. This event gave the Sima clan effective control over Wei.

Sima Yi died in 251 AD. His descendants later founded the Jin dynasty, fulfilling his ambition. He was posthumously honored as Emperor Xuan of Jin, though he never ruled as emperor himself.
