Colocolo vs Gwangjong of Goryeo

Colocolo, as an elder leader, called for the Mapuche tribes to unite under a single war leader to resist Spanish incursions. His speech at a council of chiefs helped establish the toqui system, leading to the election of Lautaro as the first toqui.

Colocolo participated in the Battle of Tucapel, where Mapuche forces under Lautaro defeated and killed Spanish governor Pedro de Valdivia. This victory was a turning point in the Arauco War, demonstrating Mapuche military capability.

After Lautaro's death, Colocolo was elected toqui to lead the Mapuche resistance. He organized military campaigns against the Spanish, continuing the war effort and maintaining the unity he had advocated for.

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.
