The earliest known Korean pottery dates back to around 8000 BCE or before, and evidence of Mesolithic Pit-Comb Ware culture or Yungimun Pottery is found throughout the peninsula.

An example of a Yungimun-era site is in Jeju-do.

Jeulmun or Comb-pattern Pottery is found after 7000 BCE, and pottery with comb-patterns over the whole vessel is found concentrated at sites in west-central Korea when a number of settlements such as Amsa-dong exist.

Jeulmun pottery bears basic design and form similarities to that of the Russian Maritime Province, Mongolia, and the Amur and Sungari River basins of Manchuria and the Jomon culture in Japan.

Examples of Early Jeulmun settlements include Seopohang, Amsa-dong, and Osan-ri.

Deep-sea fishing, hunting, and small semi-permanent settlements with pit-houses characterize the Early Jeulmun period (from about 6000 BCE to about 3500 BCE).

Radiocarbon evidence from coastal shell midden sites such as Ulsan Sejuk-ri, Dongsam-dong, and Ga-do Island indicates that shellfish were exploited, but many archaeologists maintain that shellmiddens (or shellmound sites) did not appear until the latter Early Jeulmun.

The earliest Korean art appears in the form of Neolithic pottery impressed with simple geometric decoration around 3000 BCE.

Maritime East Asia (2205–2062 BCE): Agricultural Expansion, Cultural Decline, and the Birth of the Xia Dynasty

Between 2205 BCE and 2062 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—experiences crucial transformations marked by shifts in agricultural practices, climatic upheaval leading to cultural decline, and foundational events associated with legendary Chinese rulers. These developments notably include the agricultural practices of Korea's Middle Jeulmun period, the climatic challenges that cause the decline of China's flourishing Longshan culture, and the rise of legendary figures like Shun and Yu the Great, culminating in the establishment of China’s first hereditary dynasty, the Xia Dynasty.

Middle Jeulmun Agriculture on the Korean Peninsula

During Korea’s Middle Jeulmun period (ca. 3500–2000 BCE), agricultural practices gain importance as a supplement to traditional subsistence methods. Archaeological evidence from at least fourteen sites across the peninsula confirms early cultivation practices through finds such as carbonized plant remains and agricultural stone tools.

Notably, Dongsam-dong Shellmidden in southern Korea yields direct AMS radiocarbon dates for domesticated foxtail millet (Setaria italica ssp. italica), firmly placing its cultivation within this era (Crawford and Lee, 2003). Additional evidence, though somewhat controversial, emerges at Jitam-ri (Chitam-ni) in present-day North Korea. Here, excavations of pit-house structures yield carbonized grains described by local archaeologists as domesticated millet, although limitations in excavation methods and documentation leave room for scholarly debate.

Nevertheless, cultivation remains largely supplementary during this era. Subsistence in Korea continues heavily emphasizing deep-sea fishing, shellfish gathering, and hunting. Simultaneously, the distinctive "Classic Jeulmun" pottery, known locally as Bitsalmunui, develops, characterized by intricate comb-patterning, cord-wrapping, and decorative patterns covering entire vessel surfaces. This pottery is primarily identified in west-central and southern coastal Korea, reflecting regional cultural developments and the increasing complexity of Jeulmun societies.

Collapse of the Late Longshan Culture in China

In China, this period witnesses a dramatic demographic and cultural shift associated with a major climatic event, the 4.2 kiloyear BP aridification event (around 2200 BCE). The previously thriving Longshan culture—known especially for its refined black pottery and urbanizing settlements—faces severe environmental challenges, including drought, cooling climate, and declining agricultural productivity, particularly affecting the Yishu River Basin.

The resulting agricultural failures, notably impacting rice production, lead to substantial population reductions, societal fragmentation, and the disappearance of sophisticated ritual pottery characteristic of the Longshan tradition. Around 2000 BCE (4000 cal. yr BP), archaeological records show that Longshan settlements are gradually replaced by simpler, less sophisticated, and more fragmented cultural groups.

Legendary Chinese Rulers: Shun and Yu the Great

Concurrently, legendary historical narratives transmitted through later Confucian texts provide context for China’s social and political transformations. According to these traditions, the virtuous sage-emperor Shun rules during this time, symbolizing moral integrity and exemplary governance. Shun’s reign is credited with key administrative accomplishments, including standardizing weights and measures, organizing China into twelve administrative provinces, and regulating waterways and infrastructure projects.

Shun’s most significant legacy, however, is his choice of successor, Yu the Great—the celebrated hero famed for controlling the catastrophic flooding of previous decades. Yu is honored in later traditions as a foundational figure, renowned for his mastery of waterways and his pioneering role in early Chinese bronze technology. Cultural memory of Yu survives in rituals such as the Taoist Yu’s Step, a ritual dance commemorating the distinctive limp Yu reportedly developed due to his exhausting labors in flood control.

Establishment of the Xia Dynasty

Around 2070 BCE, according to Chinese literary tradition, Yu the Great officially establishes the Xia Dynasty, China’s first imperial dynasty characterized by hereditary succession. Named after Yu’s own Si clan, the Xia Dynasty symbolizes the crucial transition from tribal or collective leadership structures to formal, dynastic monarchy. Some early historical sources alternatively suggest the Xia Dynasty originated as a confederation of agricultural village leaders organized primarily for defense against northern nomadic intrusions from Mongolia and Manchuria.

Though modern historians debate the Xia Dynasty’s precise historical veracity, its cultural importance is undisputed. Yu’s reign, particularly his legendary founding acts—including organizing China into nine zhou (provinces) during meetings at Mount Miao—establishes an enduring template for subsequent Chinese imperial administration.

Legacy of the Era: Climatic Stress, Cultural Resilience, and Dynastic Foundations

Thus, the era 2205–2062 BCE represents a decisive turning point in Maritime East Asia’s historical and cultural trajectory. On the Korean Peninsula, early agricultural experimentation complements traditional subsistence strategies, signaling nascent complexity within Jeulmun societies. In China, environmental stress triggers the decline of the previously dominant Longshan culture, marking a pivotal cultural shift toward simpler, dispersed societies. Meanwhile, legendary sage-rulers Shun and Yu symbolize enduring models of governance, moral virtue, and technological innovation, culminating in the foundational legacy of China’s earliest recognized dynasty—the Xia.

These developments set critical precedents, profoundly shaping the social, political, and cultural foundations upon which future civilizations throughout Lower East Asia continue to build.

At least fourteen sites from Korea's Middle Jeulmun period (circa 3500-2000 BCE) have yielded evidence of cultivation in the form of carbonized plant remains and agricultural stone tools. (Choe, C P and Martin T Bale (2002) Current Perspectives on Settlement, Subsistence, and Cultivation in Prehistoric Korea. For example, Crawford and Lee, using AMS dating techniques, directly dated a domesticated foxtail millet (Setaria italica ssp. italica) seed from the Dongsam-dong Shellmidden site to the Middle Jeulmun (Crawford, Gary W. and Gyoung-Ah Lee 2003. Agricultural Origins in the Korean Peninsula. Antiquity 77(295):87-95.).

Another example of Middle Jeulmun cultivation is found at Jitam-ri (Chitam-ni) in North Korea.

A pit-house at Jitam-ri yielded several hundred grams of some carbonized cultigen that North Korean archaeologists state is millet.

However, not all archaeologists accept the grains as domesticated millet because it was gathered out of context in an unsystematic way, only black-and-white photos of the find exist, and the original description is in Korean only.

Cultivation was likely a supplement to a subsistence regime that continued to heavily emphasize deep-sea fishing, shellfish gathering, and hunting.

"Classic Jeulmun" or Bitsalmunui pottery in which comb-patterning, cord-wrapping, and other decorations extend across the entire outer surface of the vessel, appeared at the end of the Early Jeulmun and is found in West-central and South-coastal Korea in the Middle Jeulmun.

Maritime East Asia (2061–1918 BCE): Xia Dynasty Traditions, Agricultural Diversification, and Austronesian Expansion

Between 2061 BCE and 1918 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—experiences significant cultural and agricultural developments. Key highlights include legendary cultural traditions associated with the early Xia Dynasty in China, the diversification of agriculture with the introduction of wheat, and the arrival and settlement of Austronesian-speaking ancestors of Taiwan’s indigenous peoples.

Xia Dynasty Traditions and Cultural Innovations

According to Chinese historical tradition, the early Xia Dynasty—regarded as China's first hereditary dynasty—solidifies around 2070 BCE under the legendary leadership lineage begun by Yu the Great. Mythological accounts prominently feature the Yellow Emperor (Huangdi) as a foundational ancestor of Han Chinese civilization, crediting him with vital cultural and scientific innovations. These include the development of the core principles of traditional Chinese medicine, invention of the Chinese calendrical system (including the sexagenary cycle), and establishing standardized musical pitch (huang chung, or "yellow bell") fundamental to later Chinese musical traditions.

These narratives significantly shape Chinese historical identity, emphasizing foundational virtues and cultural continuity rooted deeply in the legendary Xia period.

Austronesian Expansion and Early Settlement in Taiwan

During this same era, significant demographic and cultural transformations occur on Taiwan. Archaeological evidence confirms human habitation dating back roughly 30,000 years, but around 2000 BCE, ancestors of modern Taiwanese indigenous peoples, speaking Austronesian languages, settle permanently on the island. These ancestral populations are culturally and genetically connected with groups in maritime Southeast Asia, sharing maternal lineage links with the broader Polynesian population.

Taiwan thus emerges as a critical early node in the Austronesian migration network, eventually leading to widespread maritime settlement across the Pacific. This early Austronesian presence on Taiwan has enduring implications, linking Taiwan’s indigenous peoples culturally and linguistically with diverse Pacific and Southeast Asian communities.

Introduction and Establishment of Wheat Cultivation

Another crucial agricultural advancement in southern, central, and northeastern China during this era is the introduction of wheat cultivation, around 2000 BCE. Wheat’s arrival significantly diversifies agricultural productivity and diets, enhancing food security and laying foundations for increasingly complex, stable, and prosperous societies. Wheat farming complements existing staple crop systems based on rice and millet, thus strengthening agricultural resilience in Lower East Asia’s varied environmental contexts.

Legacy of the Era: Foundations of Cultural Complexity and Diversity

Thus, the era 2061–1918 BCE profoundly impacts Maritime East Asia through foundational legendary traditions of the early Xia Dynasty in China, major agricultural innovations, and early Austronesian migrations into Taiwan. These developments reinforce the region’s central role in the historical evolution of East Asian civilization and cultural diversity, setting enduring precedents for future regional historical trajectories.

Maritime East Asia (1917–1774 BCE): The Erlitou Culture and Early Bronze Age Developments

Between 1917 BCE and 1774 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—sees significant cultural and technological developments marked prominently by the rise and spread of the influential Erlitou culture. This early Bronze Age society, named after its principal archaeological site at Erlitou in Yanshi, Henan Province, represents a crucial stage in the evolution of complex urban societies and metallurgy in ancient China.

Rise and Spread of the Erlitou Culture

The Erlitou culture flourishes roughly between 2000 BCE and 1500 BCE, with its largest and most influential site located at Erlitou itself, spanning approximately three kilometers in diameter. This prominent settlement likely serves as a central hub for ritual, political, and economic activity, notably monopolizing the sophisticated production of ritual bronze vessels. These vessels become distinctive markers of Erlitou craftsmanship, signaling the emergence of specialized metallurgy and advanced artisan traditions during China’s early Bronze Age.

Geographic Expansion and Regional Influence

Originating from antecedent late-Neolithic Longshan cultural traditions, Erlitou rapidly expands its cultural influence beyond Henan Province, spreading significantly throughout neighboring regions including Shanxi, and subsequently influencing areas of Shaanxi and Hubei provinces. The widespread geographic distribution of Erlitou cultural artifacts—particularly ritual bronzes—suggests extensive regional networks of trade, cultural exchange, and possibly political alliances or control extending throughout central and northeastern China.

The Erlitou Culture and the Xia Dynasty Debate

A significant scholarly debate centers on Erlitou’s potential association with the legendary Chinese Xia Dynasty, traditionally described in historical texts but not conclusively linked to archaeological sites. Most Chinese archaeologists consider Erlitou the physical manifestation of the Xia Dynasty, citing chronological alignment and geographic coherence with textual descriptions. In contrast, many Western archaeologists remain cautious, emphasizing the absence of written records directly linking the Erlitou archaeological findings with the historical narrative of the Xia Dynasty.

This debate underscores the importance of Erlitou as a key archaeological culture bridging prehistoric traditions and historical accounts, regardless of its direct dynastic connections.

Legacy of the Era: Foundations of Urbanization and Bronze Technology

Thus, the period from 1917 BCE to 1774 BCE marks a pivotal chapter in the historical trajectory of Maritime East Asia, particularly within China’s central and northeastern regions. The emergence and regional expansion of the Erlitou culture signify critical transitions toward urban complexity, sophisticated metallurgical practices, and increased social stratification. These innovations lay lasting foundations for subsequent cultural and historical developments across Lower East Asia.

Maritime East Asia (1773–1630 BCE): Decline of the Xia Dynasty and Early Innovations

Between 1773 BCE and 1630 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—undergoes significant transitions, particularly in ancient China, as the legendary Xia Dynasty faces internal decline, setting the stage for dynastic transformation. Concurrently, early cultural innovations, notably the development of traditional Chinese ink, contribute to regional cultural sophistication.

Kong Jia and the Decline of the Xia Dynasty

According to ancient textual sources such as the Bamboo Annals, the Xia Dynasty—traditionally considered China’s earliest hereditary dynasty—experiences substantial internal decline under its fourteenth ruler, Kong Jia, who reigns approximately from 1789 BCE to 1758 BCE. Governing from the Xia capital located at West River, Kong Jia is remembered unfavorably as a ruler excessively preoccupied with superstition, indulgence in alcohol, and pursuits of pleasure.

His ineffective governance and neglect of administrative responsibilities lead to a gradual weakening of centralized royal authority. During and after Kong Jia’s rule, regional vassal kings gain increasing autonomy and power, undermining Xia dominance. This progressive decentralization of authority continues throughout subsequent generations, ultimately leading to the dynasty’s downfall when the powerful vassal king, Tang of Shang, overthrows the last Xia ruler, Jie, establishing the Shang Dynasty in approximately 1618 BCE.

Early Chinese Ink Traditions

Around the same era, notable cultural advancements occur within Lower East Asia, specifically in the early development of Chinese ink. Historical evidence traces ink-making traditions back to approximately the 18th century BCE, featuring the use of naturally derived inks made from plants (plant dyes), animals, and mineral sources such as graphite. These materials are ground with water to produce inks applied using specially crafted brushes, laying critical foundations for future literary, artistic, and cultural expression throughout China and, eventually, broader East Asia.

The emergence of these early inks underscores the increasing sophistication of cultural practices within the region, marking significant steps toward later artistic and literary traditions.

Legacy of the Era: Dynastic Transition and Cultural Innovation

Thus, the period 1773–1630 BCE marks a critical era in Maritime East Asia’s early historical trajectory. The gradual collapse of the Xia Dynasty—symbolized by Kong Jia’s ineffective reign—paves the way for major political transformations, while concurrent innovations such as early ink-making practices highlight the region’s advancing cultural complexity. These developments significantly shape the historical and cultural evolution of Lower East Asia in subsequent periods.

Maritime East Asia (1629–1486 BCE): Rise and Consolidation of the Shang Dynasty

Between 1629 BCE and 1486 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—experiences a pivotal transition with the fall of the quasi-legendary Xia Dynasty and the rise of the historically attested Shang Dynasty. This era is marked by significant cultural advancements, including the introduction of sophisticated bronze metallurgy, the establishment of Chinese writing, and the formation of distinct social hierarchies, laying lasting foundations for Chinese civilization.

Fall of the Xia Dynasty

According to traditional Chinese historical accounts—including the Xia Shang Zhou Chronology Project—the Xia Dynasty’s last ruler, Jie, reigns for fifty-two years until approximately 1618 BCE. Jie’s oppressive and corrupt rule, characterized by tyranny and cruelty, precipitates the dynasty’s downfall. Later historical records, particularly the Bamboo Annals, describe catastrophic natural phenomena during Jie's final years, including unusual climatic events such as frost in July, heavy rains, crop failures, and an anomalous "yellow fog" accompanied by dim sunlight and multiple suns appearing simultaneously. Modern scientists speculate that these phenomena could have been related to volcanic events, notably the Thera eruption, linking environmental disturbances to historical upheaval.

Ultimately, Jie is overthrown by Tang of Shang at the pivotal Battle of Mingtiao, marking the end of Xia dominance and the beginning of a new era under the Shang Dynasty.

Rise and Expansion of the Shang Dynasty

Emerging prominently around 1600 BCE, the Shang Dynasty establishes dominance in North China’s Henan region, absorbing smaller kingdoms including the remnants of the Xia state. Archaeological evidence and historical texts—particularly Sima Qian’s Shiji (Records of the Grand Historian) and later Zhou Dynasty documents—indicate the Shang people share an ethnic affinity with the Huaxia peoples of the Yellow River basin.

The Shang society is fundamentally agrarian, supplemented by hunting and animal husbandry, and characterized by advanced urban centers supporting complex social stratification. Notably, the Shang Dynasty represents an early Chinese "slave society," structured hierarchically from the king and ruling elite—including royal family members, nobility, priesthood, and specialized artisans—down to the urban craftspeople, village agriculturists, and, at the bottom, enslaved populations.

Bronze Metallurgy and Cultural Achievements

During this period, sophisticated bronze metallurgy rapidly develops, transforming Shang society. Bronze-casting technology, previously undocumented at this level of sophistication in China, emerges fully formed, enabling the production of intricate ritual vessels, ceremonial weapons, and artistic objects. Shang bronze-working also enhances the crafting of jade artifacts, integrating multiple advanced artistic practices.

Development of Early Chinese Writing

The Shang Dynasty is critically significant for developing an early and fully operational system of Chinese writing. This script, evident in surviving inscriptions on bronze artifacts, oracle bones (turtle shells, cattle scapulae, and other bones), pottery, jade, and other media, indicates a complex writing system already mature by this period. Although the direct antecedents of Shang script remain obscure, it is widely assumed to have evolved from earlier hieroglyphic forms, attesting to a long period of development.

These oracle bone inscriptions represent China's earliest substantial corpus of recorded written characters, providing invaluable insights into Shang society, religion, governance, and daily life.

Religious Practices and Social Organization

Shang religion prominently features worship of the supreme deity Shangdi (Shang-ti), alongside rituals and prayers directed toward ancestral spirits. Ritual practice includes human sacrifice, reflecting beliefs about the afterlife, divine favor, and dynastic legitimacy. The Shang’s distinct religious and social systems solidify political cohesion, enforce hierarchical relationships, and reinforce the centralized authority of the king.

Legacy of the Era: Foundations of Historic Chinese Civilization

Thus, between 1629 and 1486 BCE, Maritime East Asia witnesses profound historical transformation as the Shang Dynasty supplants Xia, bringing advances in bronze metallurgy, sophisticated writing systems, hierarchical social structures, and centralized governance. These developments shape the essential foundations of historic Chinese civilization, significantly influencing subsequent cultural and political evolution in the region.
