Unveiling the Banshan and Machang Cultures

Discovered in the early 20th century by Swedish archaeologist Johan Gunnar Andersson, the Banshan (半山) and Machang (马厂) cultures represent the late phase of the Majiayao culture (3300–2000 BCE) along the upper Yellow River. Named after their respective type sites in Gansu and Qinghai provinces, these cultures flourished between 2500–2000 BCE, producing some of China’s most spectacular Neolithic painted pottery while revealing complex social transformations.

Historical Discovery and Early Research

Andersson’s 1923–1924 surveys identified key sites at Banshan (广河半山) and Machangyuan (民和马厂塬), initially classifying them within his “Gansu prehistoric culture” sequence. His assistant Nils Palmgren later published Ceramic Grave Goods from Banshan and Machang (1934), establishing foundational typologies. Chinese archaeologists expanded this work dramatically:

– 1940s: Xia Nai and Pei Wenzhong documented new sites like Qinggangcha (青岗岔), proving Banshan had residential areas, not just cemeteries.
– 1950s–60s: Rescue excavations along railway projects uncovered Machang kilns at Baidaogouping (白道沟坪) and clan cemeteries at Midixian (糜地岘).
– 1970s–80s: Systematic large-scale excavations at Liuping (柳湾, 1,700+ tombs) and Yangshan (阳山) revealed unprecedented social complexity.

Geographic Distribution and Key Sites

Centered in the Tao River (洮河) and Huangshui Valley (湟水), these cultures spanned:

– Banshan (2500–2300 BCE): From Shaanxi’s Long County to Qinghai’s Tongde, with eastern (Tianshui), central (Lanzhou), and western (Qinghai) regional variants.
– Machang (2300–2000 BCE): Expanded northwest to Jiuquan in the Hexi Corridor, with distinct eastern (Qinghai) and western (Gansu) pottery styles.

Notable sites include:
– Qinggangcha (青岗岔): Proved Banshan had dwellings, debunking “burial-only” theories.
– Liuping (柳湾): The largest cemetery (3,000+ grave goods), showing Machang’s social stratification.
– Yangshan (阳山): Revealed ritual pits with animal sacrifices and unique painted drums.

Cultural Characteristics and Innovations

### Pottery: A Canvas of Neolithic Art

Banshan pottery featured bold black-and-red geometric designs (60–90% painted ware), including:
– Swirling vortex patterns
-锯齿纹 (jagged-edge motifs)
-葫芦形纹 (gourd-shaped designs)

Machang innovations introduced:
-蛙纹 (anthropomorphic frog motifs)
– 400+ symbolic variations in圈纹 (concentric circles)
– Novel forms like human-faced jars and double-mouthed vessels

### Metallurgy and Crafts

While Banshan showed no metal use, Machang yielded early bronze artifacts:
– A tin-bronze knife at Jiangjiaping (蒋家坪)
– Copper cones and ingots in Jiuquan

Textile production boomed, with 338 spinning wheels found at Liuping alone, many intricately decorated.

Social Structure and Belief Systems

### Burial Practices

– Banshan: Egalitarian clan cemeteries (e.g., 66 tombs at Dibaping 地巴坪) with modest grave goods, suggesting matrilineal organization.
– Machang: Emerging inequality—some tombs had 95 offerings (Liuping M564), while others held just 1–2 pots.

Notable finds:
– Shamanic artifacts: Stone masks with bone-inlaid eyes (Yangyangchi 鸳鸯池 M51)
– Gender markers: Men buried with axes, women with spindle whorls

### Ritual and Symbolism

– Yangshan’s 12 sacrificial pits contained burnt animal bones, indicating ancestor worship.
– Painted drums (35–43 cm long) featured animal-hide fasteners for ritual use.
– 1,000+ pottery marks at Liuping may denote clan symbols or early writing prototypes.

Legacy and Connections

These cultures bridged Majiayao and later Bronze Age societies:
– Banshan → Machang: Clear stylistic evolution in pottery forms.
– Machang → Qijia Culture: Stratigraphy at Liuping shows Qijia tombs cutting through Machang layers.

In the Hexi Corridor, Machang possibly influenced the Siba culture (四坝文化), while eastern areas saw direct transitions to Qijia.

Conclusion: A Pivotal Neolithic Transition

The Banshan-Machang period marked northwest China’s shift from egalitarian communities to hierarchical societies. Their artistic achievements—particularly in painted pottery—remain unmatched in Neolithic Eurasia, while metallurgical experiments foreshadowed the region’s Bronze Age zenith. Ongoing research continues to unravel their role in shaping early Chinese civilization along the Yellow River’s upper reaches.
