Abd al-Mumin vs Gwangjong of Goryeo

After the death of Ibn Tumart, Abd al-Mumin was proclaimed caliph of the Almohad movement. He consolidated the Berber tribes of the High Atlas under Almohad doctrine, establishing the foundation for a new dynasty that would challenge Almoravid rule.

Abd al-Mumin captured Marrakesh, the capital of the Almoravid Empire, after a prolonged siege. The Almoravid ruler Ishaq ibn Ali was killed, and the city became the Almohad capital, marking the end of Almoravid rule in North Africa.

Abd al-Mumin extended Almohad control across the Maghreb, conquering cities such as Fez, Tlemcen, and Algiers. He defeated local Berber dynasties and unified the region from the Atlantic to Tripolitania under a single centralized administration.

Abd al-Mumin launched a campaign into Al-Andalus, capturing cities including C

Abd al-Mumin implemented a centralized administrative system across his empire, appointing governors and judges loyal to the Almohad doctrine. He standardized taxation and military organization, creating a stable state structure that lasted for decades.

King Gwangjong issued a decree freeing thousands of slaves and commoners who had been unjustly enslaved. This reform weakened the power of the aristocratic clans, strengthened the central monarchy, and increased the tax-paying population of Goryeo.

Gwangjong introduced a Chinese-style civil service examination (gwageo) to select government officials based on merit rather than birth. This reform reduced the influence of the entrenched aristocracy and promoted a more centralized, bureaucratic state.

King Gwangjong ordered the execution or exile of numerous powerful nobles and their families, including many who had opposed his reforms. This violent purge eliminated opposition to his centralization policies but created a climate of fear and resentment among the elite.
