How Joseon began: a Confucian state
In 1392 the general Yi Seong-gye took the throne and ended the older Goryeo kingdom. He chose Hanyang (today's Seoul) as capital in 1394. Thinkers such as Jeong Do-jeon gave the new kingdom its ideas: Neo-Confucianism. This means a ruler should be moral, officials should be educated, families should respect elders, and good government should look after the people.
Joseon also borrowed the Chinese Ming order: it sent envoys to the Ming court and kept peace with its neighbours. King Sejong (1418-1450) is famous for science, music and the Korean alphabet Hangul (announced in 1446).
How Joseon was governed: ministries, watchdogs and exams
The king was at the top, but he was not free to do anything. A State Council of senior ministers advised him. Six Ministries did daily work: Personnel (officers), Taxation, Rites (ceremony and education), Military, Punishment (law) and Public Works.
Three Offices were like watchdogs. They could criticise officials, and even the king, and they looked after the royal library and advice. This was a way to check power.
To become an officer one had to pass the gwageo, a hard written exam on Confucian books. Society had four broad layers: yangban (scholar-officials), jungin (middle people such as doctors and translators), commoners (mostly farmers) and low-status people (cheonmin). In practice most exam-takers came from yangban families, so the system was fairer than birth alone but not equal.
Hungu, Sarim and the factions
The first officials who helped found the kingdom and their families are called Hungu (meritorious officials). They held land and high posts. The Sarim were Neo-Confucian scholars who lived in the countryside, ran village academies called seowon, and said that rulers and officials must follow moral rules strictly.
Between 1498 and 1545 four purges removed many Sarim from office. But their schools stayed, and under King Seonjo (1567-1608) they took control of the court. Soon they argued among themselves, and in 1575 split into Easterners (Dongin) and Westerners (Seoin). Later they divided further. Factional fighting became a long habit of Joseon politics.
Japanese and Manchu invasions: effects on Korea and East Asia
In 1592 Japanese armies under Toyotomi Hideyoshi crossed the sea and attacked. This is the Imjin War (1592-1598). Joseon had few ready soldiers at first. Admiral Yi Sun-sin won sea battles with strong ships (including the turtle ship), village volunteers called righteous armies (uibyeong) fought back, and Ming China sent soldiers to help.
Later, in 1627 and 1636, Manchu armies from the north attacked Joseon. Joseon had to accept the Manchu (soon the Qing) as superior in 1637.
Effects: farmland, towns, books and tax records were destroyed, and many people died or fled. Outside Korea, the war weakened the Ming, helped the Qing rise in 1644, and ended the Toyotomi rule in Japan. A long period of peace followed for Joseon, Qing China and Edo Japan.
Repair and change in late Joseon: tax reform, commerce and Silhak
After the wars the state needed money. The Daedongbeop began in 1608 and spread over about a hundred years. Instead of villages sending many different local goods, farmers paid one tax by the size of their land, in rice, cloth or coin. This was fairer and made trade easier.
Farming improved (rice transplanting, new tools) and commerce grew: markets in towns, merchants, and copper coins (from 1678). Some farmers and traders became rich.
Silhak means "practical learning". Scholars such as Yu Hyeong-won (land reform), Park Ji-won (trade and tools) and Jeong Yak-yong (government reform) asked for useful ideas instead of only old books.
Kings Yeongjo (1724-1776) tried to cool factional quarrels and cut the military cloth tax in half in 1750. Jeongjo (1776-1800) opened the Gyujanggak library, welcomed scholars and built Hwaseong fortress.
Sedo politics and peasant uprisings
After Jeongjo died in 1800, several kings came to the throne as children or were weak. A few in-law families (such as the Andong Kim clan) ruled in their name. This is called sedo politics. Officials bought their posts and then collected extra from farmers through the three tax systems (land, grain loans and military cloth).
Anger turned into action: the Hong Gyeong-rae uprising (1811), the Imsul uprisings (1862) and the Donghak movement (founded 1860 by Choe Je-u; a big peasant war in 1894). Foreign ships and demands also pressed Korea in the 1800s. The dynasty ended in 1910.
Try it: build your own Joseon timeline
Take a long strip of paper (or use the slider in the 3D). Mark 1392 at the left end and 1910 at the right. Put in these dates: 1392, 1446, 1575, 1592, 1608, 1636, 1750, 1811, 1862, 1894. Colour 1392-1592 blue, 1592-1636 red, 1636-1800 green and 1800-1910 orange. Predict: which colour is the longest? Then measure and check. Finally, for each red or orange date write one cause and one effect.
Key formulas and definitions
- Joseon: 1392 to 1910 = 518 years
- Capital: Hanyang (Seoul), from 1394
- Government: king + State Council + Six Ministries + Three Offices (checks) + gwageo exam
- Social layers: yangban, jungin, commoners, cheonmin
- Hungu = founding-era officials; Sarim = village Neo-Confucian scholars; seowon = their academies
- Imjin War = 1592-1598 (Japan); Manchu invasions = 1627 and 1636
- Daedongbeop = one land tax in rice, cloth or coin (from 1608)
- Silhak = practical learning; sedo politics = rule by in-law families after 1800
Worked examples
1. How many years did Joseon last? Which period is longer: before or after the Imjin War?
1910 - 1392 = 518 years. Before the war: 1592 - 1392 = 200 years. After: 1910 - 1592 = 318 years. So the period after the Imjin War is longer.
2. Explain how the Three Offices and the gwageo showed Confucian ideas.
Confucian thought says rulers must be moral and officials must be learned. The Three Offices could criticise the king and officials, so power was checked. The gwageo tested knowledge of Confucian books, so officers were chosen for learning. Both aim at good, moral government.
3. Why did the Daedongbeop make tax fairer?
Earlier, villages had to send many different local goods, and officials and middlemen took extra. The Daedongbeop asked for one tax by the size of land in rice, cloth or coin. People with more land paid more, small farmers paid less, and there was less room for cheating.
4. Make a cause-and-effect chain linking sedo politics to the 1862 Imsul uprisings.
Child king -> in-law family rules -> posts are sold -> officials collect extra tax from farmers -> farmers are in debt and angry -> Imsul uprisings in 1862.
Common mistakes
- Thinking the Sarim and Hungu were two countries or two religions. Both were officials and scholars inside Joseon; they argued about power and morals.
- Mixing up the two invasions. 1592 is Japan (Imjin War, from the sea); 1627 and 1636 are the Manchu (from the north).
- Saying Joseon was ruled by the king alone. The ministries and the three watchdog offices limited his power.
- Saying Silhak was a school of art. It means practical learning about land, trade, tools and government.
