The Historical Backdrop of Qin Dynasty Sichuan

The archaeological discoveries spanning from the 1950s to the early 2000s in Sichuan Province reveal a fascinating intersection of cultures during the Qin Dynasty (221–206 BCE) and the preceding Warring States period. These excavations—particularly at sites like Baxian’s Dongshuiba, Guangyuan’s Zhaohua Baolunyuan, and Fuling’s Xiaotianxi—paint a vivid picture of a region undergoing profound transformation.

Sichuan, then known as Ba and Shu, was conquered by the Qin state in 316 BCE, marking the beginning of intensified cultural exchange. The burial practices and artifacts uncovered reflect a blend of indigenous Ba-Shu traditions, Qin administrative influences, and even distant echoes of Chu and Central Plains customs. This period was pivotal as the Qin state, soon to unify China, consolidated its control over this resource-rich frontier.

Key Discoveries and Their Chronological Significance

### Boat Coffins and the Blending of Cultures

The 1954–1957 excavations at Dongshuiba and Baolunyuan uncovered 97 ancient tombs, including distinctive “boat-coffin burials.” These elongated pits, some containing nested inner coffins, held artifacts like bronze mou cauldrons, iron tools, and a rare “string-pattern mirror” (M42). The presence of Qin-style items alongside Ba-Shu pottery suggests these may date to the Qin occupation era (316–221 BCE).

A 1995 follow-up at Baolunyuan revealed nine additional burials—eight with boat coffins—further underscoring this hybrid funerary tradition. The boat coffins themselves, a Ba-Shu hallmark, now incorporated Qin metalwork, signaling cultural adaptation under new political realities.

### The Xiaotianxi Elite Burials: A Window into Power

The 1972 and 1980 digs at Fuling’s Xiaotianxi yielded spectacular finds. Tomb M1 contained ritual bronze bells and weapons, while M2 produced an exquisite “double-dragon” openwork mirror. Most striking was M3’s inscribed halberd: “Made in the 26th year by Shu Governor Wu.” Paleographic analysis suggests this could reference either 281 BCE (Qin’s King Zhao) or 221 BCE (Qin Shi Huang’s unification year).

The M3 artifacts—including a silver-inlaid bronze pot and three ceramic fu cauldrons—show stylistic parallels with Qin terracotta army weapons and late Warring States funerary trends. This challenges initial dating, pushing some burials into the early imperial period.

### Qingchuan’s Legal Connection

The 1979–1980 Qingchuan Haojiaping excavations uncovered 72 Warring States tombs. M50’s wooden slip records a 309 BCE land law reform under Chancellor Gan Mao, offering rare administrative insight. The tomb goods—particularly lacquerware like twin-phoenix painted flasks—closely resemble those from Yunmeng’s Shuihudi Qin tombs, suggesting these burials may extend into the Qin unification era.

Cultural Synthesis in Mortuary Practices

### The Fourfold Legacy

Sichuan’s Qin-era burials exhibit a unique fusion:

1. Ba-Shu Traditions: Boat coffins, bronze ge dagger-axes, and round-bottomed guan jars persist.
2. Qin Innovations: Flat-bottomed fu cauldrons, iron tools, and banliang coins appear.
3. Chu Influences: White clay sealing (seen in Yingjing tombs) and compartmented coffins reflect southern contacts.
4. Central Plains Rituals: Ding-hu ceramic ritual sets mimic Zhou aristocratic customs.

This synthesis mirrors the Qin’s pragmatic governance: imposing standardization while permitting local elites to retain certain traditions.

### Lacquerware as Cultural Mediator

Sites like Yingjing’s Chengguan (1977) and Qingchuan produced exquisite lacquers—round boxes, ear cups, and flasks—often bearing workshop marks like “Chengting.” The avoidance of the character bang (forbidden after 202 BCE due to Emperor Gaozu’s naming taboo) helps date these to the Qin period. These artifacts, combining Chu craftsmanship with Qin administrative labeling, epitomize the era’s cultural brokerage.

The Broader Historical Implications

### Reassessing Regional Chronologies

The artifacts compel reevaluations. For instance:
– Dated weapons like Xiaotianxi’s halberd refine Qin occupation timelines.
– Ceramic typologies (e.g., fu cauldron shapes) link distant sites like Baolunyuan and Dayi Wulong.
– Coinage studies reveal how Qin’s banliang currency system permeated Sichuan.

### Sichuan’s Role in Qin’s Unification

These burials underscore Sichuan’s strategic value. The Chengdu Plain’s agricultural wealth fueled Qin’s campaigns, while its craftsmen supplied lacquer and bronzes. The presence of Qin-style weapons in elite tombs (e.g., Xiaotianxi’s ceremonial halberds) illustrates military-ceremonial integration.

Modern Resonances and Ongoing Mysteries

Today, these finds reshape understandings of early Chinese empire-building. The Sichuan excavations demonstrate that Qin’s “uniformity” was more nuanced—a negotiated balance between centralization and local identities.

Key unanswered questions remain:
– Were boat-coffin practitioners assimilated Ba elites or Qin-adopting locals?
– How did Chu cultural elements travel so far inland?
– What role did Sichuan’s mines play in supplying Qin’s bronze standardization?

Ongoing digs—like Shifang’s 98 tombs (1988–2002)—continue to reveal new layers. Each discovery, from a humble dou stemmed cup to an inscribed halberd, adds another stroke to our portrait of ancient Sichuan’s transformative epoch.
