Joseon's king purged the scholars who checked his power — and lost his only warning system
In 1545, King Myeongjong's regent purged the Sarim scholars who challenged the throne. The purge removed the court's feedback mechanism. Factional wars began.

What it means today
Every company that fires the whistleblowers, silences the analysts, or restructures the team that raised the alarm has the Gisa Sahwa problem. The purge removes the early warning. The question is whether the organisation can afford to be blind.
What happened
The Gisa Sahwa (己卯士禍, 1545) was the third of the Joseon dynasty's literati purges. Queen Munjeong, regent for the young King Myeongjong, purged the Sarim scholars — the Neo-Confucian literati who had challenged the throne's authority and the power of the queen's clan (the Yun family).
The Sarim scholars were the court's feedback mechanism: they remonstrated with the king, challenged the ministers, and held the throne accountable to Confucian principles. The purge removed them from the court. Some were executed; others were exiled. The queen's clan consolidated power.
The purge did not end the factional conflict — it intensified it. The surviving Sarim scholars regrouped and returned to the court in subsequent reigns, seeking revenge. The factional wars between the Sarim and the Hungu (merit subjects) consumed Joseon politics for the next century. The purge that was meant to silence the scholars created a cycle of revenge that weakened the dynasty from within.
Why it happened
- The purge removed the court's feedback mechanism: the Sarim scholars were the only institution that could challenge the throne's decisions. Without them, the court had no early warning
- The purge was driven by clan politics, not policy: the Yun family used the purge to eliminate its rivals, not to reform the government. The scholars were killed because they were in the way
- The purge created a cycle of revenge: the surviving scholars returned in subsequent reigns and purged their enemies. Each purge weakened the court further, until the factional wars consumed it
The lesson
An organisation that purges the people who challenge its decisions does not silence the challenge — it removes the early warning. The Sarim scholars were the court's feedback. The purge blinded it.
Aftermath
The Gisa Sahwa was followed by three more literati purges (1545, 1547, 1589, 1591). The factional wars between the Sarim and the Hungu continued for over a century. The Joseon dynasty survived until 1897, but its capacity to govern was permanently weakened by the cycle of purges and revenge.
