935-1637 CE
The Koreans of the Goryeo and early Joseon periods built one of the most technologically advanced civilizations in medieval East Asia, producing the world's first movable metal type, the Tripitaka Koreana woodblocks, and the hwach'a rocket launcher while fending off Mongol, Japanese, and Manchu invasions.
The Goryeo dynasty unified the Korean peninsula after the collapse of Silla in 935 and gave Korea its English name. For nearly five centuries Goryeo governed a kingdom that combined Buddhist devotion with Confucian administration and produced some of the finest ceramics and printed texts in the medieval world. When internal decay and Mongol pressure brought Goryeo down, the Joseon dynasty that replaced it in 1392 reoriented the state toward Neo-Confucian principles and built a society of remarkable scholarly intensity.
Through both dynasties the Koreans occupied a position between great powers, absorbing influences from China while maintaining a distinct identity, trading with Japan while guarding against its raids, and enduring invasions that tested the limits of national survival. The peninsula's geography, mountains in the interior and sea on three sides, helped. Korean stubbornness helped more.
Korea's landscape is mountainous, with arable land concentrated in the western and southern coastal plains. Rice paddies dominated the lowlands, barley and millet grew on the higher ground, and the surrounding seas provided fish, seaweed, and salt. The agricultural calendar governed rural life: spring planting, summer tending, autumn harvest, winter survival. A farmer guiding an ox-drawn plow through a flooded paddy near Jeonju in April worked land that his family had probably cultivated for generations, paying rent in grain to a landlord who might never visit.
Cities were administrative centers rather than commercial hubs. Kaesong under Goryeo and Hanyang under Joseon served as capitals where the court, the bureaucracy, and the aristocracy concentrated. Markets existed but were regulated. Craftsmen produced celadon pottery of extraordinary quality, its jade-green glaze and inlaid designs representing a technical achievement that Chinese potters acknowledged with envy. A celadon cup with inlaid cranes in a Goryeo court official's hand was both a drinking vessel and a statement of civilizational confidence.
Korea's military history is defined by defensive wars against neighbors with larger armies. The Mongol invasions of the thirteenth century devastated the peninsula over decades of resistance. The court retreated to Ganghwa Island, where the sea channel protected it from Mongol cavalry, and ordered the carving of the Tripitaka Koreana, over eighty thousand woodblocks of Buddhist scripture, as a spiritual appeal for divine protection. The blocks survive today in pristine condition at Haeinsa temple, each one hand-carved with a precision that suggests the carvers believed their work would save the nation.
The Japanese invasions of 1592-1598 tested Korea again. Admiral Yi Sun-sin's turtle ships, armored vessels with spiked roofs and dragon-head prows, destroyed Japanese supply fleets and turned the naval war decisively in Korea's favor. On land, guerrilla resistance and Ming Chinese reinforcements eventually drove the Japanese out. The hwach'a, a wheeled launcher that fired hundreds of rocket-propelled arrows in a single volley, was among the weapons Korean defenders deployed. The peninsula survived, but the devastation was immense.
Goryeo was a Buddhist state. Monasteries held vast estates, monks advised kings, and Buddhist ceremonies marked every significant event in the court calendar. The transition to Joseon brought a deliberate shift toward Neo-Confucianism as the governing ideology. Buddhism was suppressed, monasteries lost their lands, and the scholar-official class, the yangban, became the dominant social group. A yangban household valued scholarship above all: a father drilling his son on the Four Books and Five Classics in preparation for the civil service examination was investing in the family's future status and livelihood.
King Sejong's creation of the hangul alphabet in 1443 was an act of deliberate democratization. The existing writing system used Chinese characters, which took years of study to master and effectively restricted literacy to the yangban. Hangul was designed to be learnable in a day, so that even a peasant woman could read royal proclamations and write a letter. The yangban resisted it precisely because it worked. A servant reading a notice posted on a village wall in hangul script was doing something that had been impossible a generation earlier.
Korea's cultural relationship with China was deep but not subservient. Korean scholars studied Chinese texts, Korean potters refined Chinese techniques, and Korean political institutions followed Chinese models, but the results were distinctly Korean. The celadon tradition surpassed its Chinese origins. Korean Neo-Confucianism developed its own philosophical debates. The Tripitaka Koreana was the most complete and accurate edition of the Buddhist canon anywhere in East Asia, a scholarly achievement that Chinese and Japanese institutions could not match.
Korean printing technology led the world. Movable metal type was developed in Korea in the early thirteenth century, over two hundred years before Gutenberg, though it was used primarily for government and scholarly publications rather than mass printing. The technological sophistication coexisted with political vulnerability: Korea endured Mongol domination, Japanese devastation, and ultimately Manchu conquest in 1637. Each time the state was damaged, the culture survived. A scholar copying a text by lamplight in a ruined city was performing the same act of preservation that the Tripitaka carvers had performed on Ganghwa Island centuries earlier, trusting that knowledge outlasts destruction.

In the game, the Koreans win through scholarship, not conquest. The Tripitaka Koreana's eighty thousand woodblocks were carved in the belief that accumulated knowledge could save a nation, and here that belief is mechanically true: white cubes on recurrent technologies, especially Age I cards holding up to 5, convert directly to glory. The attack bonus for leading the technology grid reflects Joseon military innovations like the hwach'a, born from a culture that approached warfare as an engineering problem. Research broadly across all four classes rather than specializing; each complete set multiplies instant achievement payoffs. Fill the grid, guard your knowledge lead, and let the library do what armies cannot.
Yes. The ability requires you to have more action cubes on the technology grid than every other player individually. You have 2, each opponent has 1, so you qualify.
Knowledge recurrent achievements, described on the bottom part of green achievement cards. This ability lets you claim such achievements from multiple cards: the public knowledge achievement, your own secret card if it has one, and any other player's secret card that has been placed into the public zone.
Yes. You choose the order in which your abilities activate during the achievement phase, so you can count those cubes for glory before any other effect removes them.
No. Although you choose the activation order, each ability must be fully resolved before the next one activates. You cannot interleave partial resolutions of different abilities.
