- The spread of Christianity challenged established Confucian beliefs and political authority.
- Donghak learning emerged as an Indigenous response to social inequality and the increasing influence of foreign ideas.

Syllabus focus
• Rise of Sedo (factional) politics and the weakening of royal authority
• Spread of Christianity
• Threat of Donghak learning
• Heungseon Daewongun’s reforms (1864–1873) and isolation policy
🏛️ Sedo Politics and Weakening Royal Authority
Meaning of Sedo politics
- Sedo politics developed when powerful families connected to the royal household gained control of government.
- Royal in-law families exercised influence over appointments, taxation and political decision-making.
- Government offices increasingly served the interests of powerful factions rather than the monarchy or the wider population.
- Weak kings found it difficult to control court factions and provincial officials.
Impact on the monarchy
- Royal authority declined as important decisions were made by dominant court families.
- Competition for government office encouraged corruption and factional conflict.
- Provincial officials frequently imposed heavy financial demands on peasants.
- Government weakness reduced the monarchy’s ability to respond effectively to economic hardship and social unrest.
- The declining authority of the monarchy created demands for stronger central government and reform.
✝️ Spread of Christianity
- Christianity spread in Korea despite government restrictions and persecution.
- Christian teachings challenged elements of the established Confucian social and political order.
- Opposition to ancestral rituals created conflict with Confucian officials.
- The religion attracted some people because it offered a spiritual community not based entirely on the established social hierarchy.
- The monarchy associated Christianity with increasing European intervention and regarded it as a threat to political independence.
- Persecution did not prevent Christianity from continuing to spread.
Political significance
- Christianity connected religious change with the wider problem of foreign influence.
- Government persecution created additional tension between Korea and Christian foreign powers.
- The failure to eliminate Christianity demonstrated the limits of royal authority.
☯️ Threat of Donghak Learning
- Donghak, meaning “Eastern Learning”, emerged as a Korean response to Western Learning and Christianity.
- It combined elements of established Korean religious and philosophical traditions.
- Donghak opposed foreign influence and criticized social injustice.
- Its ideas appealed particularly to peasants and groups dissatisfied with corrupt officials and social inequality.
- The movement’s growing popular support caused the monarchy to regard it as a political and social threat.
- The execution of its founder did not prevent Donghak learning from continuing to spread.
👑 Heungseon Daewongun’s Reforms (1864–1873)
Restoration of royal authority
- Daewongun governed as regent for the young King Gojong.
- He attempted to reduce the power of royal in-law families and court factions.
- Government administration was reorganized to strengthen central control.
- He sought to limit privileges associated with powerful Confucian institutions and the yangban elite.
- His reforms were intended to rebuild the authority of the monarchy.
Financial and social measures
- Daewongun attempted to reform taxation and make privileged groups contribute more to state finances.
- The reconstruction of the royal palace was intended to demonstrate renewed royal power.
- However, the financial and labour demands connected to reconstruction created dissatisfaction.
- Opposition from established elites limited the long-term success of his reforms.
🚪 Isolation Policy
- Daewongun attempted to protect Korea from foreign political, religious and commercial influence.
- Christianity was persecuted because it was associated with foreign intervention.
- The government resisted attempts by foreign powers to establish relations and open Korea to trade.
- Isolation was intended to preserve Korean sovereignty, culture and the established political order.
- It temporarily restricted foreign influence but did not remove growing external pressure.
- Korea’s isolation also limited its ability to respond to the military and technological power of neighbouring states.
📊 Nature of the Challenges
| Challenge | Impact on the Monarchy |
|---|---|
| Sedo politics | Powerful factions controlled government and weakened royal authority. |
| Christianity | Challenged the Confucian order and increased concerns about foreign intervention. |
| Donghak | Mobilized dissatisfaction with inequality, corruption and foreign influence. |
| Foreign pressure | Exposed the limitations of isolation and Korea’s military vulnerability. |
| Daewongun’s reforms | Temporarily strengthened central authority but generated elite and popular opposition. |
⚖️ Historical Assessment
The monarchy’s greatest internal weakness was the growth of Sedo politics because factional control reduced royal authority and encouraged corruption. Christianity and Donghak created additional challenges by questioning established religious, social and political structures.
Daewongun restored some central authority, but his policies did not resolve Korea’s deeper problems. His isolation policy temporarily resisted foreign influence but left Korea increasingly vulnerable as regional powers expanded their military and imperial ambitions.
