Mostly agreedGood evidence; some details, dates or numbers uncertain.
Korea's Bronze Age farming era, named for its plain pottery, when rice, bronze and chiefs appeared.
See it on the Korean History map →What happened
From about 1500 BC, plain pottery (무문토기, 'patternless') replaced comb-pattern ware across the peninsula. People farmed millet, beans and barley and, from about 1000 BC, rice, some in irrigated paddies. Villages grew large, some ringed by ditches and wooden palisades, as at Songguk-ri in Buyeo. Bronze daggers and polished stone daggers marked rank, and leading families were buried under dolmens. Iron spread from about 300 BC, closing the era.
Why it matters
Farming surpluses created rich and poor, chiefs and territories, the raw material of Korea's first states; rice became the base of Korean life for 3,000 years.
How we know
Excavated villages, paddy fields and charred rice, plus dolmens and bronze finds, dated by radiocarbon. The name comes from archaeologists' pottery classification.
Still debated
Whether farming spread with migrants from Liaoning and Shandong or through locals adopting it, and how this relates to the spread of the Korean language, is debated.

Connections (7)
▸Jeulmun (comb-pattern pottery) period gave way to Mumun (plain pottery) periodMostly agreed
The connection
Around 1500 BC, plain pottery, rectangular longhouses and more intensive farming of millet and rice replaced comb-pattern ware and the old foraging mix. The shift came with new crops, stone tools and later bronze, probably carried at least partly by migrants from Liaoning and the north.
When and how
Across the peninsula, roughly 1500–1300 BC; the change is clearest in central and southern Korea.
How sure are we?
Site layers and radiocarbon dates show the pottery change; charred rice and new tool types appear alongside plain ware.
Debates and open questions
Migration versus local adoption, how much Jeulmun people contributed to later Koreans, and what languages each group spoke are debated.
▸Bangudae Petroglyphs (Ulsan) may instead date to Mumun (plain pottery) periodDebated
The connection
The main alternative view dates Bangudae to the Bronze Age Mumun period, when larger, more organized communities lived in the region. Supporters cite the style of the figures and comparisons with other Korean rock art, much of which is usually dated to the Bronze Age.
When and how
Ulju County, Ulsan; a Bronze Age date was widely held in the decades after the 1971 discovery and still has supporters.
How sure are we?
Dating rests on style, comparison with other rock art and nearby finds; no carving has been dated directly, so the link is inferred.
Debates and open questions
The panel may hold layers carved over many centuries, so both datings could be partly right.
▸Amsa-dong Neolithic village (Seoul) foreshadowed the farming villages of Mumun (plain pottery) periodMostly agreed
The connection
Amsa-dong's permanent riverside houses, storage pits, stone hoes and grinding stones previewed the settled villages that became full farming communities in the Mumun period. Mumun villages were larger, with longhouses, fields and rice, but the habit of settling by rivers came first.
When and how
Han River basin, Seoul region: Amsa-dong about 5000–3000 BC; Mumun villages from about 1500 BC.
How sure are we?
Comparison of house types and tools across excavated sites; the link is a broad trend, not a direct line of descent.
Debates and open questions
Whether Amsa-dong's people actually farmed, beyond gathering wild plants, is debated.
▸Mumun (plain pottery) period saw the building of most Korean dolmensMostly agreed
The connection
Mumun farming surpluses let local leaders gather crews to quarry, haul and raise multi-tonne capstones. Most of Korea's tens of thousands of dolmens were built in this era, often in clusters near villages, as graves and monuments for leading families.
When and how
Throughout the peninsula, mostly about 1000–300 BC; densest in the southwest, around Gochang and Hwasun.
How sure are we?
Mumun pottery, stone daggers and bronze objects found in dolmen burials; radiocarbon dates from excavated dolmens.
Debates and open questions
When dolmen-building began, possibly before 1000 BC, and why it was so intense in Korea remain open questions.
▸Mumun (plain pottery) period underlay the rise of GojoseonMostly agreed
The connection
Bronze Age farming created the surpluses, ranks and chiefdoms from which states grow. In Liaoning and northwest Korea, related Bronze Age cultures, with mandolin daggers and table dolmens, became Gojoseon's base. Mumun, strictly a term for the peninsula's center and south, shows the same process under way.
When and how
Liaoning and the Korean Peninsula, about 1000–300 BC; Joseon appears in Chinese records from roughly the 7th–4th centuries BC.
How sure are we?
Archaeology shows growing villages, elite burials and bronze weapons in the same centuries Chinese texts begin naming Joseon.
Debates and open questions
How directly southern Mumun communities were tied to Gojoseon, politically or culturally, is unclear.
▸Mandolin-shaped (Liaoning-style) bronze dagger was a hallmark of Mumun (plain pottery) periodMostly agreed
The connection
In the southern peninsula, mandolin daggers are prestige items of the Mumun period, found in rich graves such as the stone-cist tomb at Songguk-ri. Rare and costly, they marked rank; polished stone daggers, perhaps imitating bronze ones, were far more common.
When and how
Central and southern Korea, roughly 900–400 BC; Songguk-ri in Buyeo, excavated from 1974, is a key site.
How sure are we?
Daggers excavated together with Mumun pottery in dated graves and settlements.
Debates and open questions
Whether early examples were imported from Liaoning before local casting began, and when local workshops started, are debated.
▸Jeongok-ri hand axes long predate the bronze tools of Mumun (plain pottery) periodMostly agreed
The connection
The contrast spans almost all of Korean prehistory. Jeongok-ri's chipped stone hand axes are tens or hundreds of thousands of years older than the cast bronze daggers and polished stone tools of the Mumun period. Between them came pottery, settled villages and farming.
When and how
Jeongok-ri tools roughly 300,000–40,000 years ago; Mumun bronzes from about 1000 BC; both found in central Korea.
How sure are we?
Geological dating of the Jeongok-ri layers and radiocarbon dating of Mumun sites put them far apart in time.
Debates and open questions
The size of the gap depends on Jeongok-ri's disputed age.
