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
  • Welfare/reform measures
    • Insaeng-an policy: reduced taxes for the people
    • Heuk: a poverty-relief period
  • Ten Injunctions (moral guidelines for future kings)
    • Emphasized:
      • Support for Buddhism
      • Attention to the Stone Sutra
      • Lantern Festival
      • Protecting the pagans (as phrased in the subtitles)
      • Vigilance against the Khitan

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

Central and Local Administrative Systems (Government Structure)

Central Governance Structure

  • 2 ministries + 6 departments
  • Two ministries:
    • Jungseomunhaseong (highest central office; state affairs decided here)
    • Sangseoseong
  • Additional central bodies:
    • Jungchuwon (royal secretariat)
    • Eosadae (inspection body)

    • Under them: Jumok-hyeon
    • Special areas: Hyangbu-gokso
    • Further breakdown:
      • Juyeon (officials dispatched) vs Sok-hyeon (no officials dispatched)
      • Notably, So-hyeon outnumbered Juyeon even into the Goryeo period
    • Hyang-ri governed local areas, linked to remaining hojok

Military Administration

    • Composed of Buk-gwe and Dong-gye
    • Byeongmasa dispatched to these Yanggye
    • Jins established at strategic locations

      • One army is described as an invading force vs another guarding capital/borders
  • Provincial forces:
    • Juyong Army (nine years)
    • Jujin Army (two border regions)

Education

  • Gukjagam in Gaegyeong (highest state educational institution)

    • Benefit granted to children of high-ranking officials (5th rank or higher)
    • Allows entry to government without another civil exam
    • 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)

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
  • “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)
