Jia Chong vs Qusayy ibn Kilab

Jia Chong married a daughter of Sima Zhao, strengthening his ties to the Sima clan. This marriage aligned him with the future Jin dynasty and ensured his political survival after the Cao Wei collapse. It also gave him influence over succession matters.

Jia Chong ordered the assassination of Emperor Cao Mao after the emperor led a coup against Sima Zhao. When Cao Mao attacked Sima Zhao's residence, Jia Chong's troops killed him. This act eliminated the last Cao emperor who resisted Sima control.

Jia Chong was appointed Minister of Works under the Jin dynasty, becoming one of its highest-ranking officials. He played a key role in consolidating Sima Yan's rule and was instrumental in the conquest of Wu, serving as a strategist and administrator.

Qusayy ibn Kilab gathered the scattered Quraysh clans in Mecca and established a unified tribal confederation. He organized the administration of the Kaaba and the city, creating a central authority that would control Mecca's political and religious life for centuries.

Qusayy ibn Kilab founded Dar al-Nadwa, the assembly house in Mecca where Quraysh leaders gathered to discuss political, military, and religious matters. This institution became the central council for Quraysh governance, managing alliances, declarations of war, and marriages.

Qusayy ibn Kilab secured the keys to the Kaaba and the rights to provide water and food to pilgrims. This gave his clan, the Banu Abd al-Dar, control over the most important religious and economic privileges in Mecca, solidifying his family's dominance.
