Main Ideas / Lessons (Political History Focus)
Origins of Goryeo (Late Unified Silla → Later Three Kingdoms)
- Goryeo’s origins trace back to the late Unified Silla period, when aristocratic power struggles enabled strong local clans (hojok) to rise.
- Founders of the rival states:
- Gyeonwon (Later Baekje)
- Gungye (Later Goguryeo)
- Gungye’s rule
- Moved the capital
- Renamed the state to Taebong
- Became increasingly tyrannical
- Fall of Gungye
- Powerful Later Goguryeo clans overthrew Gungye
- They installed Wang Geon
- Wang Geon later founded Goryeo in 918
- Unification under Wang Geon
- Wars against Later Baekje
- Silla integration via surrender of King Gyeongsun, tied to developments involving defectors and internal strife
- Unity completed in 936
Wang Geon (Taejo)’s Integration Policy: Weaken hojok While Gaining Their Cooperation
Taejo pursued unification by combining inclusion with control.
- How he built his power base
- Embraced refugees from Silla and Later Baekje
- Co-opted powerful local clans (hojok) for political support
- Tools/methods
- Marriage alliances (Wang Geon married a daughter of a hojok)
- Granting royal titles to hojok to secure alliances
- Systems that controlled hojok
- Sasin-gwan system
- Appointed hojok members into local governance roles
- The principle was to impose authority and responsibility so they could not dominate unchecked
- Example cited: Kim Bu, last king of Silla
- Giin system
- Kept clan children as hostages in the capital to control clan power
- Sasin-gwan system
- Welfare/reform measures
- Insaeng-an policy: reduced taxes for the people

- Support for Buddhism
- Attention to the Stone Sutra
- Lantern Festival
- Protecting the pagans (as phrased in the subtitles)

- Emphasized:
After Taejo: Political Instability → Gwangjong Strengthens Central Rule
- After Taejo’s death, Goryeo faced chaos from intense power struggles.
- Gwangjong is presented as the key monarch who stabilized the realm.
Policies attributed to Gwangjong:
- Slave rights / slave eradication-related policy
- Freed people illegally made slaves, restoring their status as commoners
- Rationale: slavery was tied to powerful clans’ wealth and military strength—freeing people weakened those clans
- Civil service examinations (alongside purges)
- Strengthened royal authority
- Purged local/clan opponents to solidify the exam-centered system
- Bureaucratic discipline and symbolism
- Official uniforms for officials
- Declared himself Emperor
- Used reign names: Gwangdeok and Junpung
Successors: Institutionalization Under Gyeongjong and Seongjong
Gyeongjong
- Jeonsigwa system
- Compensation for officials based on rank
Seongjong
- Accepted Choe Seung-ro’s Simmu 28 Articles
- Adopted Confucianism as the governing ideology
- Stabilized society via governance restructuring
Key themes from the Simmu 28 Articles:
- Use external officials (the king cannot directly manage every household)
- Reduce large-scale Buddhist ceremonies (e.g., Lantern Festival and the Eightfold Path Festival)
Government reorganization actions:
- Established Mok districts nationwide and dispatched local officials
- Reorganized central governance according to Confucian ideals

- Jujin Army (two border regions)
Education
- Gukjagam in Gaegyeong (highest state educational institution)

- Subtitles describe it as a “gold spoon” system
Rise of Aristocratic Families → Contradiction → Political Upheavals → End of Goryeo
Early Goryeo Aristocracy
- Munbeol: multi-generation families formed after founding forces (hojok and Yukdu-pum) monopolized high offices
- They used:
- Eumseo
- Land grants (Nokbon, Gong-eumjeon)
- Exclusive elite leagues
Breakdown Among Elites: Lee Ja-gyeom and Injong
- Lee Ja-gyeom
- Took power through repeated royal marriages and court support
- King Injong attempted removal but failed
- Lee Ja-gyeom staged a rebellion with Jung-gyeong and seized power
- Injong later appeased Jung-gyeong, but removal attempts still failed
Myo-cheong Uicheondo Movement
- After suppressing the Lee Ja-mae rebellion, Injong promoted reform politics using the Seokgyeong faction (including Myo-cheong, Jeong Ji-sang)
- Myo-cheong advocated:
- A geomancy-based argument to relocate the capital to Seokgyeong
- Opposition to Jin Dynasty tributary relations
- Declaring himself emperor and annexing Jin (blocked by conservatives in the Gaegyeong faction)
- When Injong sided with Gaegyeong, Myo-cheong rebelled in Seogyeong
- Spread briefly, then was suppressed by government troops led by Kim Bu-sik (as stated)
Military Coup (Core Turning Point: Early vs. Late Goryeo)
- Military officials faced discrimination compared to civilian officials
- Their grievances culminated in the military coup
- Leaders named:
- Jeong Jung-bu, Yi Bang, etc.
- After the coup:
- Instability due to competition among military leaders and frequent changes in supreme authority
- Governance reorganized:
- The top body seized appointment power (previously held by military council)
- Established Seobang to seek advice from civilian officials
- Created Yabyeolcho (private army foundation), later used as military backbone
- Social consequences:
- Peasant rebellions across the country, including:
- Mang-i and Mang-soi rebellion at Myeonghakso (Gongju)
- Kim Sa-mi and Hyosim rebellion at Chojeon (Unmun)
- Manjeok Rebellion
- A slave under Choe Chung-won challenged social hierarchy (quoted question about separate lineage among kings, generals, ministers)
- Peasant rebellions across the country, including:
Mongol/Yuan Period and Goryeo’s Subordination
- Mongol invasions worsened conditions
- Goryeo defended itself but became subject to Yuan
Yuan actions described:
- Establishing Ssangseong Commandery in Hwaju
- Establishing Tamna Commandery of the Dongmyeong Unit in Seogyeong
- Creating Jeongdong Province for an expedition to Japan, with demands for labor/supplies
- Lowering royal/government status and allowing the Goryeo king to marry a Yuan princess
- Frequent demands for tribute and “tribute women”
Collaboration power group:
- Gwonmunsejok
- Grew by exploiting Yuan control
- Controlled the Dopyeonguisa (Council of State)
- Atrocities described:
- Forced confiscation of peasants’ land
- Enslaving them
Reform Attempts in Late Yuan Era → Anti-Yuan Independence Under Gongmin
When Yuan momentum weakened
- King Chungnyeol sought reforms:
- Reclaim territories seized by Yuan (including Dongnyeongbu and Tamnak Chonggwanbu)
- Reduce the tyranny of Yuan officials
Anti-Yuan independence and reforms under Gongmin
- King Gongmin is singled out as especially important:
- Eradicated powerful Jianmun clans
- Abolished Jeongdong Haengseong Imunseo (described as a Yuan interference institution)
- Attacked Ssangseong Chonggwanbu to recover northern territory against Ming
- Video references an exam-important map of recovered territory
- Appointed Sin Don
- Established Jeonmin Byeonjeong Dogam
- Confiscated large estates illegally acquired by powerful aristocrats
- Freed those forcibly enslaved and restored them to commoner status
Late Dynasty Shift: Scholar-Officials + Military Leadership → Joseon Foundation
- Under Gongmin’s reforms, a new force emerged:
- Sinjin Sadaebu (New Scholar-Officials), with Neo-Confucian emphasis
- Representative: Jeong Do-jeon
- Late Goryeo also saw a new military force through resistance:
- Red Turbans and the Outer Army
- Founding Joseon:
- Jeong Do-jeon (scholars) + Yi Seong-gye (military leader) cooperated
- Yi Seong-gye disobeyed the king and seized power via Weihwado Retreat
- This led to Goryeo’s 500-year collapse, culminating in Joseon
Methodology / Ordered Instructional Elements (Exam-Focused)
How to Organize the Later Three Kingdoms Unification (Exam Emphasis)
- Start with founding events:
- Later Baekje founded by Gyeonwon
- Later Goguryeo founded by Gungye
- Explain Later Goguryeo’s internal collapse:
- Tyrannical rule by Gungye → powerful clans drive him out → enthrone Wang Geon
- Trace unification step-by-step:
- Wang Geon battles Later Baekje
- Address the dispute leading to Gyeonwon’s overthrow by his son (per subtitle)
- Use Silla integration:
- Yi defecting to Goryeo leads to King Gyeongsun surrender → Silla is incorporated first
- Finish with conquest:
- Wang Geon defeats remaining Later Baekje forces
- Completion in 936
- Memory associations:
- Wang Geon = Taejo Gohwangje
- Unification process described as “recurring on exams”
How Goryeo’s State-Building Was Framed (Repeatable “Policy Logic”)
- “Co-opt hojok, then control them”
- Co-optation:
- Marriage alliance
- Titles
- Control:
- Sasin-gwan + Giin
- Co-optation:
- “Centralize power”
- Slave-related policy to weaken clan economic/military bases
- Civil service exams + purges to reduce opposition
- Bureaucratic discipline (uniforms) and ideological governance (Confucianism)
