Introduction
The Zhou 周 dynasty was built on conquest, and military power was a cornerstone of its political organization. However, Zhou martial dominance was a double-edged sword. On the one hand, it enabled the Zhou’s sweeping expansion across China. On the other hand, the Zhou royal court’s lack of commensurate infrastructural reach and administrative capability to implement direct rule in conquered lands distant from the Zhou royal centers in the Wei 渭 River valley necessitated a decentralized political structure in which a great measure of local control was delegated to the regional nobility. In current scholarship, the balance of central and regional political power within this framework has often been examined through such lenses as the Zhou kinship and ritual order, whereas the role of military institutions as a prime integrative factor for the geopolitical cohesion of the Western Zhou state (ca. 1045–771 BCE) has arguably been presumed more than it has been comprehensively explored.Footnote 1 To address this gap, this study unpacks certain underlying organizational aspects of Western Zhou military power, particularly those relating to the dynamics between central authority and regional governance.
This pattern was common to many other regimes besides the Zhou across both Chinese and world history: an initial burst of wide-ranging military conquest followed by dispersed modes of local rule and governance heavily reliant on the cooperation of local elites to alleviate natural logistical obstacles posed by geographic distance.Footnote 2 The fundamental problem, as articulated by Owen Lattimore decades ago, was essentially that “the radius of military action was greater than that of civil administration.”Footnote 3 In other words, the principles behind expending military force (warfare) and sustaining it to enforce long-term rule (governance) were closely interrelated but differed meaningfully in their operation. Throughout history, rulers and states attempted to surmount this problem by employing different forms and applications of military coercion in combination with various other social, ideological, and diplomatic strategies.
For early China, the strategic organization of military power in relation more broadly to the logistics of government and the political structure of the state has received somewhat less attention than it has for later periods of Chinese history.Footnote 4 Partly, this is due to the relative scarcity of evidence for the pre-imperial period; the Qin 秦 and Han 漢 periods are better documented.Footnote 5 Accordingly, previous scholarship has investigated this issue through examining such topics as the discourses surrounding the classic dichotomy of the civil and the martial (wen 文 and wu 武).Footnote 6 However, while this conceptual pair is related to the present study’s concern with the relationship between government and warfare, political and military power, it was largely anachronistic, at least as it is formulated in our late first millennium BCE sources, in the context of the Western Zhou.
This article investigates the relationship between the central and regional military organization of the Western Zhou state, focusing especially on the inscriptional and archaeological evidence relating to a military unit called Qi shi 齊師. This “Qi army” or “Qi garrison” has conventionally been understood to refer to the military forces of the Zhou regional domain of Qi 齊 in northern Shandong.Footnote 7 Here, I consider an alternative interpretation: Qi shi was a regional garrison directly administered by the Zhou royal court, one of potentially several such centrally maintained military bases that served to extend the royal court’s political reach by facilitating the coordination of central and regional military resources. These regional garrisons may thus have functioned as an important integrative mechanism that counterbalanced some of the centrifugal pressures inherent in the decentralized geopolitical structure of the Western Zhou state.
Western Zhou geopolitical strategy
The Zhou victory over Shang 商 at the Battle of Muye 牧野 marked only the beginning of a century of prolonged Zhou political and military expansion through which the ascendant Zhou dynasts cemented their position as the new masters of the Central Plain 中原.Footnote 8 This initial phase of territorial expansion in the early Western Zhou period tapered off after the catastrophic southern campaign of King Zhao’s 昭 (r. 977/75–957 BCE) final regnal year, in which the king himself perished together with a core contingent of the Zhou military.Footnote 9 Thereafter in the mid- and late Western Zhou periods, Zhou geopolitical strategy pivoted to defense and consolidation, especially in the face of increasingly threatening conflicts with foreign enemies such as the Southern Yi 南夷 of the Huai 淮 River Basin to the southeast and the Xianyun 玁狁 to the northwest.Footnote 10
The Zhou realm stretched across a sizeable geographic expanse as far as the Jiaodong 膠東 Peninsula in the east and the Jianghan 江漢 Plain in the south—approximately 1,100 km and 600 km as the crow flies, respectively, from the Zhou royal centers in the Guanzhong 關中 Basin (see Figure 1).Footnote 11 But across much of this landscape, Zhou rule was extensive rather than intensive. While the Zhou king was able to wield a higher degree of control over the lands and aristocratic lineages in the Zhou royal domain, spatial constraints limited the direct administrative reach of the royal court beyond this zone.Footnote 12 As reckoned by Li Feng 李峰, deploying troops from the Wei River valley to the Central Plain and relaying communications across these regions may have required as long as two months.Footnote 13

Two main geopolitical strategies were implemented to mitigate these logistical challenges. First, the Zhou king installed subordinate elite lineages at key strategic locations across the realm, constructing a wide network of Zhou regional domains (also called regional states) to reinforce Zhou authority and safeguard the royal court’s political and economic interests in outlying regions.Footnote 14 Second, the eastern royal enclave of Chengzhou 成周 was founded in present-day Luoyang 洛陽, Henan, to bridge the royal and regional domains and provide the royal court more immediate access to its holdings in the east.Footnote 15 These strategies further facilitated the incorporation of local polities of non-Zhou origin into the wider Zhou sphere of influence.Footnote 16
As conduits of Zhou political and martial power across China, the regional domains thus constituted a critical component of Western Zhou geopolitical organization. However, reliance on the regional domains simultaneously necessitated a level of organizational decentralization in the Western Zhou state. The regional lords delegated to rule the regional domains on behalf of the Zhou king typically retained their own military forces and were invested with local decision-making powers that authorized them to conduct affairs within their own jurisdictions with considerable autonomy.Footnote 17 Given these conditions, incidents of disloyalty or rebellion against Zhou suzerainty could greatly undermine central authority, as seen, for instance, in the rebellion of E 鄂 in the mid-ninth century BCE.Footnote 18 Eliciting the loyalty and cooperation of the regional lords was therefore vital for sustaining Zhou central control in the long term. We know of several different mechanisms that were utilized to prevent the regional domains and their rulers from drifting too far from the orbit of the Zhou royal court. For example, regional rulers may have been expected to pay court from time to time, and there is some evidence for officials called royal inspectors (jian 監) dispatched to surveil the regional domains.Footnote 19
However, in current scholarship, the brunt of the explanatory weight concerning the question of the Western Zhou state’s political unity and integration has been borne by the socio-ritual underpinnings of the Zhou political system. In the kin-ordered Zhou world, lineage rank and affiliation as well as genealogical seniority (i.e., proximity to the primary line of the Zhou royal lineage) were of paramount importance in determining one’s status, ritual privileges, and, ultimately, access to different forms of power. Thus, many of the major regional domains were ruled by collateral lines of the Zhou royal house to begin with, and essentially every important non-kin elite lineage in the Zhou realm had affinal ties to the Zhou royal family. Thus regional rulers were subordinate to the Zhou king not merely in a political sense but also according to multifaceted Zhou social and ritual hierarchies.Footnote 20 These kinship networks bound the elite lineages of Zhou China to both the Zhou royal house and to one another, acting as a potent integrative force that even outlasted the Western Zhou royal court itself and continued to provide a degree of solidarity for the fragmented Zhou ecumene of the subsequent Eastern Zhou period.Footnote 21
In contrast, the role of military power and infrastructure in buttressing Zhou rule has received comparatively less attention, despite the importance of Zhou military might in establishing Zhou dominion over China in the first place. In what follows, I examine Western Zhou military organization in more detail to suggest that the Zhou king maintained centralized military command and directly managed regional military bases in certain frontier regions as strategies to sustain central control beyond the immediate confines of the royal domain.
The organization of the shi 師
The overall dominance of Zhou armies on the battlefields of the era was not an automatic deterrent against either internal rebellion or foreign invasion, especially in more remote regions of the Western Zhou state. As Owen Lattimore and Michael Mann emphasize, the routine projection of military force over great distances was inhibited by logistical obstacles and difficult to achieve even for powerful states.Footnote 22 In other words, armies of conquest operated differently from armies of governance.
At the core of the Western Zhou military establishment was the shi 師 (usually written dui
in contemporary bronze inscriptions), which when referring to a kind of military organization has the dual meaning of both “army” (a body of troops) and “encampment” (a physical location).Footnote
23 The most prominent shi in Western Zhou history were the Six Armies 六師 and the Eight Armies 八師, two central military divisions that scholars have long viewed as comprising the mainstays of the Zhou military throughout the Western Zhou period.Footnote
24 The former, sometimes called the Six Armies of the West 西六師, were based in the Zhou royal domain. The latter were also called the Eight Armies of Yin 殷八師 (i.e., the late Shang capital at Anyang 安陽, Henan) or the Eight Armies of Chengzhou 成周八師 and thus based in the eastern part of the Zhou realm.Footnote
25
It is possible that the Six and Eight Armies were, at least initially, exactly as their names imply: two broad military divisions, each comprising six and eight individual shi encampments.Footnote
26 The early Western Zhou Xiaochen Lai gui 小臣
簋 (JC 4238–39) inscription hints at this possibility, as it lays out a specific campaign route taken by the Eight Armies of Yin, which departed from X shi
師, reached the sea (likely the Bohai Sea 渤海), and returned to Mu shi 牧師.Footnote
27 Contextually, X shi and Mu shi may thus have represented two discrete military encampments in the purview of the Eight Armies.Footnote
28 Of course, this remains conjecture, as the monikers Six Armies and Eight Armies may simply have stuck even as the composition and organization of these two central divisions of the Western Zhou military must have changed over time. Notably, the Eight Armies were initially concentrated in the region of Anyang but later repositioned around the region of Chengzhou.Footnote
29
In total, more than twenty named shi are mentioned in Western Zhou bronze inscriptions.Footnote 30 It is potentially significant that some shi are seen on inscribed military equipment such as horse fittings or weapons that simply state the name of the shi, perhaps akin to marks of ownership or affiliation, rather than on ritual bronze vessels. For example, the Feng Shi danglu 豐師當盧 (NA 648–49) was unearthed at the site of the Feng-Hao 豐鎬 royal center in present-day Xi’an 西安.Footnote 31 The Lü Shi ge 呂師戈 (JC 10955) hints at the possible existence of a Lü shi 呂師, likely in the Jing 涇 River valley just north of the Guanzhong Basin.Footnote 32 And Wei shi 衛師 appears on several bronze implements from early Western Zhou tombs in Hebi 鶴壁, Henan, where the regional domain of Wei 衛 was established after the Zhou conquest of Shang.Footnote 33
The exact temporal span of each known shi is difficult to establish, though they are mentioned especially frequently in early Western Zhou inscriptions. Most probably, not all known shi existed concurrently. Some may have been transient, ad hoc military units while others were more persistent garrisons. In terms of spatial distribution, the known shi appear to have been concentrated in three main regions: in and around the Zhou royal domain, on the eastern flank of the Taihang 太行 Mountains in the former Shang core region around Anyang, and at the southern frontiers of the Zhou realm. Some shi were thus located at the peripheries of the Zhou realm and clearly unrelated to the Six and Eight Armies. Given the limited evidence and the polysemy of the term shi itself, it is important to keep in mind the possibility that different varieties of shi existed, depending on time period, geographic location, and other such parameters.
More is known about the organizational structure of the Six and Eight Armies, which by the mid-Western Zhou period were large-scale military organizations with their own internal administration and matériel infrastructure. The administration of the Six Armies, for instance, included its own Supervisor of Lands (situ 司土), Supervisor of Horses (sima 司馬), and Supervisor of Works (sigong 司工), paralleling the three main supervisory offices of the Western Zhou central government. The Hu hu 曶壺 (JC 9728) inscription implies that these military-administrative hierarchies were multi-tiered and fairly elaborate, as it refers to a Chief Supervisor of Lands (zhong situ 冢司土) of the Eight Armies of Chengzhou who may potentially have been in charge of a number of junior supervisors.Footnote 34 Several royal appointment inscriptions indicate that officers were also tasked with specific duties in relation to the management and operation of the Six and Eight Armies:
Lü Fuyu pan 呂服余盤 (JC 10169)

疋(胥)備中(仲)
(司)六
(師)服Footnote
35

(司)六
(師)牧、陽(場)、大□(友?),
(司)羲夷陽(場)、佃史(事)Footnote
37
These inscriptions show that the Zhou king headed the command structure of the Six and Eight Armies and directly appointed senior officers whose responsibilities included logistics and provisioning.Footnote 38 On this point, the Nangong Liu ding is most informative, revealing that the Six Armies had their own attached assets such as agricultural fields, pastures for grazing horses and livestock, hunting grounds for conducting military drills and exercises, and the labor required to support these activities.Footnote 39 The Yi Yi 羲夷 mentioned in the Nangong Liu ding were possibly a non-Zhou community under the administration of the Six Armies. Analogous cases in other inscriptions suggest that such non-Zhou populations were an important source of labor and manpower for the Western Zhou military establishment.Footnote 40
Interestingly, despite the considerable military capital evidently amassed in the Six and Eight Armies, they seem not to have been dispatched afield too frequently as a unitary force. Only three of the sixty war-related Western Zhou bronze inscriptions collated by Shim Jae-hoon 沈載勳 explicitly mention their full deployment.Footnote 41 This suggests that the Six and Eight Armies were perhaps more effective at forestalling the enemy through their imposing presence rather than by going on the march routinely. Mobility was critical in Western Zhou warfare; the substantial scale of the Six and Eight Armies possibly rendered their mobilization en masse relatively cumbersome and costly for longer durations.Footnote 42
Instead, the prevailing military doctrine adopted by the Zhou royal court to attain its military objectives in the mid- and late Western Zhou periods, consonant with the aforementioned shift to the defensive in Zhou geopolitical strategy after the mid-tenth century BCE, was to deploy smaller but more mobile central military units in coordination with regional troops and allied local auxiliaries.Footnote 43 This use of mixed central-regional army coalitions was likely a more flexible and cost-effective approach that enabled the Zhou king to best harness the dispersed military capabilities of the regional domains. The inscriptional evidence shows that such coalitions were in all cases led by the king or by royally appointed commanders.Footnote 44 The operational difficulty of exercising such centralized military command must have been considerable in the long term, especially on fronts far removed from the Zhou royal domain. I shall now turn to examine the evidence for Qi shi to consider how some shi may have served as regional military bases providing crucial logistical infrastructure for the coordination of central and regional military assets in the Western Zhou state.
The Qi garrison
Qi shi is attested in four mid- and late Western Zhou bronze inscriptions: the Shi Mi gui 史密簋 (NA 636), Yin gui 引簋 (NB 2287), Shi Yuan gui 師㝨簋 (JC 4313–14), and Ren Xiao gui 妊小簋 (JC 4123). Collectively, these inscriptions illuminate two important points concerning the nature of Western Zhou geopolitical strategy and military organization. First, they illustrate how the Zhou royal court conducted warfare in outlying regions by using mixed coalitions of central, regional, and local military units led by centrally appointed commanders. Second, they evince the existence of a Zhou regional military garrison called Qi shi in northern Shandong. Prior to the discovery of the Yin gui at the site of Chenzhuang 陳莊 in Gaoqing 高青 County, Shandong, in 2008–2010, Qi shi was commonly thought to refer to the army of the regional domain of Qi; this new evidence raises the possibility that it may have been a separate entity directly controlled by the Zhou king.
Let us first examine the earliest of the four Qi shi inscriptions, the Shi Mi gui, discovered in Ankang 安康, Shaanxi, in 1986.Footnote 45 This inscription describes a Zhou campaign against several Yi 夷 groups that culminated in a battle fought at a place called Changbi 長必 sometime during the reign of King Gong 共 (r. 917/15–900 BCE) or King Yih 懿 (r. 899/97–873 BCE).Footnote 46 The precise location of Changbi is unknown, but commentators propose that it was possibly in southeastern Shandong, perhaps south of present-day Weifang 濰坊 or in the upper Yi 沂 River valley.Footnote 47 The Shi Mi gui inscription reads:
隹(唯)十又一月。王令(命)師俗、史密曰:「東征敆南尸(夷)。」膚(盧)、虎會杞尸(夷)、舟尸(夷), 雚(觀)不

It was the eleventh month. The king commanded Marshal Su and Scribe Mi, saying: “Campaign to the east and jointly attack the Southern Yi.” The Lu and Hu joined with the Qi Yi and Zhou Yi and, displaying recalcitrance(?), broadly attacked the eastern domains. The Qi shi, lineage footmen, and men of the suburbs then captured the captain(s) of the border region of Kuan. Marshal Su led Qi shi and the men of the suburbs, [encircling] and attacking Changbi from the left. From the right, Scribe Mi led the lineage men, the Elder of Lai, and (the men of) Bo and Yi(?) to encircle and attack Changbi, capturing one hundred men. Extolling in response to the Son of Heaven’s beneficence, I (=Scribe Mi) herewith make (for) my brilliant deceased-father Elder Yi (this) sacrificial gui tureen. Sons’ sons and grandsons’ grandsons, may they forever treasure and use (it).Footnote 48
To summarize, the Changbi campaign was provoked by the aggression (from the Zhou point of view) of several hostile Yi groups: the Lu 盧, Hu 虎, Qǐ Yi 杞夷, and Zhou Yi 舟夷.Footnote 49 To quell this threat, the Zhou king dispatched two central court officials, Marshal Su 師俗 and Scribe Mi 史密, to counterattack with a force consisting of various military units, including Qi shi. Marshal Su was a prominent high-ranking royal court official mentioned in several other extant bronze inscriptions; Scribe Mi is an otherwise obscure figure in our sources.Footnote 50 These two Zhou commanders defeated the enemy at Changbi, and Scribe Mi later had the Shi Mi gui cast to commemorate the victory.
The Zhou coalition was composed of both central and regional troops. Aside from Qi shi, the other principal detachments in this coalition were the lineage troops (zu tu 族徒 or zu ren 族人) and men of the suburbs (sui ren 遂人). Following the traditional view that Qi shi was the Qi regional domain’s army, many scholars have understood zu and sui here as referring to the lineages and suburbs of Qi.Footnote 51 Another viable reading links these military units to the Zhou royal domain, since zu as a military unit organized on the basis of kinship is well-attested in the context of the aristocratic lineages of the royal domain, and the only other contemporary evidence for the term sui refers presumably to the outlying precincts of urban centers in the royal domain.Footnote 52 Accordingly, these may have been troops drawn from the Zhou royal domain that accompanied Marshal Su and Scribe Mi in their expedition to the east.Footnote 53
Additional military support was provided by men from the local polities of Lai 萊, Bo 僰, and Yi(?)
, whose locations lend further strength to the hypothesis that the main theater of the Changbi campaign must have been near southeastern Shandong. Lai was a well-attested polity based at Longkou 龍口 in the Jiaodong Peninsula.Footnote
54 Bo has been variously identified either as Jí 棘, a settlement located north of the Wen 汶 River; Biyang 偪陽, a polity in southern Shandong; or Li 鬲 in Dezhou 德州, northwest Shandong.Footnote
55 As for the third polity, scholars have proposed to read the character
as either dian
/殿, ni 尼, or shi 尸.Footnote
56 For the time being, I follow the last of these readings, given that this same polity is also mentioned in the Shi Yuan gui inscription written as
(see below). Thus, the shi element appears to be the signifier in this word, and as shi is interchangeable with yi 夷, this polity might then be that of Yi (not to be confused with the ethnonym Yi) located in Gaomi 高密, not far south of Lai.Footnote
57
Interestingly, the Shi Yuan gui inscription lists a nearly identical group of military units involved in a Zhou campaign a century later against the Huai Yi 淮夷 during the reign of King Xuan 宣 (r. 827/25–782 BCE). This coalition was also led by a royally appointed commander, Marshal Yuan 師㝨, and consisted of Qi shi; troops from the local polities of Ji 㠱, Lai, Bo, and Yi(?)
; and the elite royal guards, the Left and Right Tiger Servants (zuoyou huchen 左右虎臣).Footnote
58 Despite the temporal gap between the events recounted in the Shi Mi gui and Shi Yuan gui, this similarity in the composition of the central-regional coalitions involved is striking, and intimates a degree of continuity in Zhou military strategy and organization across the mid- and late Western Zhou periods in this region. One imagines that the presence of Qi shi, which appears as the leading military unit in both the Shi Mi gui and Shi Yuan gui, may have contributed to this organizational stability.
Having established the general pattern of how the Zhou royal court conducted warfare in distant regions, let us now examine the question of Qi shi’s identification. Given that both Zhou campaigns recounted in the above two inscriptions took place in and involved the local polities of the Shandong region, it seems logical to assume at first glance that Qi shi must refer to the army of Qi, one of the important Zhou regional domains in Shandong. However, as Shim Jae-hoon notes, Western Zhou bronze inscriptions do not seem to explicitly refer to the armies of regional domains with the formula “domain name + shi.” Instead, their presence is indirectly indicated through mentioning the military actions of regional rulers.Footnote 59 This issue is further complicated by new information in the Yin gui inscription.
The Yin gui was unearthed in tomb M35 at the site of Chenzhuang, approximately fifty-five kilometers northwest of Linzi 臨淄, the seat of the Qi regional domain. Current scholarly consensus agrees that the Yin gui dates most probably to the period between the reigns of King Yih 懿 and Yi 夷 (r. 865–858 BCE), based on its archaeological context, stylistic features, and the inscription’s reference to the Grand Chamber of (King) Gong 共大室, which suggests that it must necessarily postdate the reign of King Gong.Footnote 60 The Yin gui records the Zhou king’s charge to Yin 引 to oversee Qi shi:
隹(唯)正月壬申。王各(格)于龏(共)大室。王若曰:「引, 余既命女(汝)更乃

It was the first month, renshen day. The king arrived at the Grand Chamber of (King) Gong. The king said to the effect: “Yin, I have already commanded you to succeed your grandfather and supervise Qi shi. I extend your charge and bestow on you one red bow, one hundred red arrows, and four horses. Respect your duty, do not abscond from service.” Yin bowed and touched his head to the ground, in response extolling the king’s beneficence. (He) gathered (his forces) at X, made pursuit, and captured weapons; and herewith makes (for) Lord You (this) treasured gui tureen. (May my) sons’ sons and grandsons’ grandsons treasure and use (it).Footnote 61
The Yin gui not only confirms that the Zhou king directly appointed the commander of Qi shi, but it also suggests that this was a position maintained over an extended period as opposed to an ad hoc one since Yin was ordered to succeed his grandfather in the same capacity.Footnote 62 This problematizes the conventional interpretation of the term Qi shi as the Qi regional domain’s army, in which case we might expect to see the Qi ruler rather than the Zhou king presiding over such matters. As Li Feng notes, insofar as we can discern from Western Zhou bronze inscriptions, “there is no evidence that the Zhou king ever interfered in the internal civil administration of the regional states.”Footnote 63 Thus, either Qi shi here does not refer to the Qi military, or if it does, the structure of Zhou military command and the relationship between the royal court and the regional domains therein must have been more complex than previously realized.
A reassessment of the nature of Qi shi and the Yin gui’s broader implications for Western Zhou military organization hinges on the critical issue of Yin’s identity. Three main theories have been proposed: (1) Yin was a Qi noble; (2) Yin was a Qi ruler; (3) Yin was a Zhou noble from the royal domain. Since none of these possibilities can be entirely ruled out at present, I will consider the merits of each in turn and present a provisional case for the third, namely that Yin was most likely a member of an aristocratic lineage of the Zhou royal domain who was charged with overseeing a Zhou regional military base located in northern Shandong called Qi shi—the Qi Garrison.
Yin was a Qi noble
This view is largely based on the burial evidence from Chenzhuang rather than information in the Yin gui inscription itself. Six bronze-bearing elite tombs were excavated at Chenzhuang in 2008–2010.Footnote 64 Aside from Yin’s tomb M35, the most notable of these burials was tomb M18, an early Western Zhou rectangular vertical pit tomb furnished with a single coffin and a container holding ritual bronzes dedicated by the tomb occupant Feng 豐 to the Duke of Qi 齊公 (i.e., Lü Shang 呂尚, the founder of Qi).Footnote 65 Feng thus appears to have been descended from the ruling house of Qi. If tombs M18 and M35 belonged to the same lineage cemetery, then Yin may have been related to Feng and by extension the ruling lineage of Qi as well, a member perhaps of one of its collateral lines.Footnote 66
However, it is not possible to conclusively establish that tombs M18 and M35 were part of the same lineage cemetery because the relationship between the elite tombs at Chenzhuang are not yet entirely clear. In fact, tomb M35 differed markedly from the comparatively simpler tomb M18 in size and structure, as it was a large jia 甲-shaped tomb with one entry ramp—the first such Western Zhou period tomb discovered in Shandong along with the adjacent tomb M36.Footnote 67 This discrepancy in class may be challenging to reconcile if Yin belonged to Feng’s lineage, as in that case his tomb would probably not so far eclipse that of his predecessor.Footnote 68 Furthermore, Kim Jung-ryol 金正烈 preliminarily observes that at least two distinct burial customs may be represented at Chenzhuang, which potentially indicates that different kin groups were interred at the site.Footnote 69
Recently renewed excavations at Chenzhuang since 2023 have yielded additional evidence that promise to lend further clarity to this issue in the near future, including four additional Western Zhou period jia-shaped tombs and a new but as-yet-unpublished bronze inscription from one of them that apparently substantiates their connection to Yin.Footnote 70 If all six jia-shaped elite tombs discovered at Chenzhuang can indeed be attributed to the same lineage, this might add more support to the view that Yin was a Qi noble, since it may be unlikely that Zhou nobles from the royal domain would maintain such a lineage cemetery in distant Shandong.
Yin was a Qi ruler
To start, it bears mentioning that no Qi ruler named Yin is mentioned in any known genealogies of the Qi ruling lineage.Footnote 71 Putting this point aside, two main lines of evidence can be marshalled in support of this theory, one based on the Yin gui inscription and the other on the nature of tomb M35. According to the Yin gui, the Zhou king bestowed on Yin a set of gifts that included a red bow and one hundred red arrows—items that also appear as royal gifts in three other extant Western Zhou bronze inscriptions. In each of these cases, their recipients were rulers of Zhou regional domains. For example, the Ying Hou Xiangong zhong 應侯見工鐘 (JC 107–8, NA 82–83), which also dates to the early ninth century BCE, records that the Zhou king bestowed on the ruler of Ying 應 the same set of items Yin received, down to their exact quantities: one red bow, one hundred red arrows, and four horses.Footnote 72 Some scholars have reasoned on this basis that Yin may have been a ruler of Qi.Footnote 73 The exceptionality of the jia-shaped tomb M35 has also been raised as a point in support of this identification, since entry ramps were generally reserved for the tombs of very high-status individuals.Footnote 74
While both the prestigious gifts bestowed on Yin and his jia-shaped tomb are certainly indicative of high rank and status, a few counterpoints can be advanced against this theory. It is indeed remarkable that the royal gifts Yin received seem mainly to have been granted to regional rulers, but another commonality between the four inscriptions mentioning these items was the military contexts in which they were granted. As such, the bestowal of this particular set of items may have been associated with military service or accomplishments, contributions both Zhou high officials and regional rulers would have made, and not necessarily with the position of regional ruler itself.Footnote 75 As for Yin’s tomb, the link between the presence (and number) of tomb entry ramps and the rank of tomb occupants was somewhat irregular in the Western Zhou period, as the tombs of high officials, lineage patriarchs, and regional rulers could all have entry ramps, and conversely, not all tombs of regional rulers had entry ramps.Footnote 76 Moreover, although no tombs of Western Zhou period Qi rulers against which to compare tomb M35 have been found, its modest burial assemblage certainly does not appear to reflect the rank of a regional ruler.Footnote 77
Yin was a Zhou noble from the royal domain
This is the position best supported by the actual content of the Yin gui inscription, which closely adheres to the standard formula of Western Zhou royal appointment inscriptions.Footnote
78 In fact, if we were to momentarily disassociate the toponym Qi from the regional domain of the same name in reading the Yin gui, we might default to assuming that Yin was a Zhou official, as there is nothing in the content of the inscription itself beyond the shared toponym Qi that links Yin and Qi shi to the regional domain of Qi.Footnote
79 Understanding Yin as a Zhou noble and Qi shi as a Zhou regional garrison furthermore clarifies the late Western Zhou Ren Xiao gui inscription, which states: “Elder Naifu tasked X to inspect the officials at Qi shi” 白(伯)
(艿)父事
(省)尹人于齊
(師).Footnote
80 While it would be unusual for Elder Naifu 伯艿父 and X
, who were presumably royal court officials, to be so closely involved in the affairs of the Qi military, this issue is resolved if Qi shi was actually a Zhou regional garrison managed by the Zhou royal court.
At this juncture, the nature of the site of Chenzhuang is worth incorporating into the discussion as well.Footnote 81 Covering an area of nine hectares, four of which comprised the core fortification encircled by walls and ditches with only one point of egress, a south gate, Chenzhuang was too small to have been a major urban settlement. Preliminary findings suggest that the walls were built during the early Western Zhou period and fell into disuse after the mid-Western Zhou period, though the site itself was continuously occupied into the Eastern Zhou period. In addition, archaeobotanical analysis of the floral remains uncovered at Chenzhuang indicates that a significant proportion may have constituted horse fodder.Footnote 82 The archaeological evidence thus strongly underscores the military character of the site, suggesting that Chenzhuang may well have been a military encampment, potentially identifiable as Qi shi itself given the discovery of the Yin gui at the same location.Footnote 83
In summary, of the three possibilities for Yin’s identity, the third scenario appears to be the cleanest conceptually: the Zhou king appointed a Zhou noble to take charge of a Zhou regional garrison. The other two scenarios are not impossible but still push us to view Qi shi as a Zhou rather than a Qi organization, as it seems to me more likely that a Qi noble would be appointed by the Zhou king to supervise a Zhou garrison than the Qi army, which would fall within the purview of the Qi ruler. Likewise, it seems more likely that a Qi ruler might be charged by the Zhou king to supervise a Zhou garrison, since it would be redundant for the Qi ruler to be specifically appointed to supervise his own domain’s army. Thus, taken together, the four Qi shi inscriptions and the archaeological evidence from Chenzhuang offer support for the view that Qi shi was a regional Zhou military garrison stationed in the geographic region of Qi. The Yin gui and Ren Xiao gui reveal that Qi shi was closely associated with the Zhou king and royal court, who oversaw the appointment of its officers and its internal administration. Meanwhile, the Shi Mi gui and Shi Yuan gui speak to the important role Qi shi played as part of mixed central-regional coalition armies led by royally appointed commanders in maintaining the security of the far eastern regions of the Zhou realm.
The role of regional military bases
Several important questions concerning the nature of the relationship between regional military bases and the regional domains in or near which they were located are raised in reevaluating Qi shi as a Zhou regional garrison. In the case of Qi shi, the connection between Chenzhuang and Qi must be accounted for (recall that Feng, a kinsman of the Qi ruling lineage, was buried at Chenzhuang), as does the apparent absence of Qi military forces in the campaigns described in the Shi Mi gui and Shi Yuan gui. Since there is little direct evidence with which to investigate these questions fully, I offer a few conjectural thoughts before looking beyond Qi shi to examine a few other relevant inscriptions that might provide an improved picture of regional garrison-regional domain relations in the Western Zhou state.
One potential explanation for Feng’s burial at Chenzhuang is simply that the stewardship of Chenzhuang may have changed hands from Feng’s lineage to Yin’s lineage at some point between the early and mid-Western Zhou periods. As discussed above, Feng’s tomb M18 was among the earliest tombs at Chenzhuang, dating to the early Western Zhou period, at which time Chenzhuang was also fortified. This means that roughly a century or slightly longer separated Feng from Yin, whose tomb M35 dates to the early ninth century BCE. Incidentally, the earliest attestation of Qi shi in the Shi Mi gui dates to sometime within this intervening century; Yin’s grandfather, ostensibly a former commander of Qi shi, would also have been active at some point during that time.
The seeming nonparticipation of the Qi regional domain in the military campaigns described in the Shi Mi gui and Shi Yuan gui inscriptions is curious given that they took place in Shandong, presumably within Qi’s remit. There is, of course, the possibility that these two inscriptions simply do not mention the involvement of the Qi military, or that Qi armies happened to be unavailable for those two particular campaigns—which might actually have been the reason it was necessary to call in support from the Zhou royal court in the first place. Another line of thought relates to the scale of Qi shi, which cannot be ascertained, but given the size of Chenzhuang may have been relatively small. Perhaps the Qi military was sufficiently large enough to strike out on its own if necessary, whereas Qi shi was a smaller force that needed to operate in concert with other military units, including auxiliaries from such minor local polities as those enumerated in the Shi Mi gui and Shi Yuan gui.
The economic and logistical support necessary to maintain regional military bases far from the Zhou royal domain are also important to consider. In this regard, cooperation with neighboring regional domains was critical since regional garrisons must have obtained the bulk of their supplies from local sources. The case of Bin shi 豳師 in the Jing River valley potentially elucidates such a symbiotic relationship between regional garrisons and regional domains.Footnote
84 According to the mid-Western Zhou Qi gui
簋 (JC 4266) inscription, Bin shi was administered directly by the Zhou royal court. The relevant part of the inscription records the royal appointment of Qi
as the garrison’s Chief Supervisor of Horses (zhong sima 冢司馬):
王若曰:「
, 命女(汝)乍(作)
(豳)
(師)冢
(司)馬, 啻官僕、射、士, 訊小大又(有)隣(憐), 取遄五寽(鋝)。」
The king said to the effect: “Qi, I command you to act as Chief Supervisor of Horses at Bin shi and specially manage the servants, archers, and soldiers. Arbitrate small and large (matters) with magnanimity, and take a stipend of five lüe units of metal.”Footnote 85
This appointment is strongly reminiscent of the previously mentioned Hu hu inscription, according to which the Zhou king appointed one Hu 曶 to be the Chief Supervisor of Land for the Eight Armies of Chengzhou. The administrative structure of Bin shi thus seems to have imitated that of the Six and Eight Armies except perhaps for a difference in scale. Additionally, given that Qi’s responsibilities included both managing troops and overseeing judicial matters, it is evident that much like the Six and Eight Armies, Bin shi was a more comprehensive military organization, probably linked to a supporting ecosystem of local lands, personnel, and resources.Footnote 86
More information about Bin shi, crucially its relationship to nearby regional domains, is provided by the mid-Western Zhou Shan ding 善鼎 (JC 2820) inscription, the relevant part of which states:
王曰:「善, 昔先王既令女(汝)左(佐)疋(胥)
侯。今余唯肈(肇)
(申)先王令=(令,令)女(汝)左(佐)疋(胥)
侯, 監
(豳)師戍。易(賜)女(汝)乃且(祖)旂。用事。」
The king said: “Shan, in the past, the former king already commanded you to aid and assist the ruler of Quan. Now I, for the first time, extend the former king’s charge and command you to aid and assist the ruler of Quan and oversee the garrison of Bin shi. (I) bestow on you your grandfather’s banner. Use (it) to serve!”Footnote 87
The most significant point to note here is the seemingly synergetic relationship between Bin shi and the local regional domain or polity of Quan
. The Shan ding makes clear that Bin shi was under the direct control of the Zhou king, much like Qi shi, and that its commander was expected to aid and assist the ruler of Quan. The implication is that there must have been a vital aspect of mutual defense and military collaboration between Quan and Bin shi. Unfortunately, little else is known about Quan including its precise location, but Bin shi, at least, was situated in a region pivotal for the defense of the royal domain, particularly in the Zhou-Xianyun wars, which may possibly have been the historical backdrop of the Shan ding.

Recently in 2018–23, archaeologists excavated the site of Xitou 西頭 in Xunyi 旬邑 County, Shaanxi, which was part of the historical region of Bin according to historical records.Footnote 89 Xitou was a walled settlement dating from the eleventh to eighth centuries BCE with a core fortified zone that encompassed an area of roughly eighty hectares. Multiple features highlight the military associations of the site, including the remains of a smelter that produced bronze weapons and other implements, as well as a large cemetery situated outside the southeast wall with horse pits and several exceptional elite tombs in which large quantities of bronze weapons, horse and chariot-related equipment, and sacrificial human victims were interred.Footnote 90 While the precise nature and chronology of the different loci and features discovered at Xitou still remains to be worked out, at minimum these new discoveries seem to corroborate the view that the broader region associated with Bin shi may have been a focal point of much Western Zhou military activity.
The case of Bin shi thus illuminates a few aspects of the symbiotic relationship between Zhou regional garrisons and regional domains. Another promising candidate for further investigation might be Gu shi 古師, which seems to be have been closely associated with the domain or polity of Hu 胡 near the southeastern boundaries of the Zhou realm in the context of the Zhou wars against the Huai Yi.Footnote 91 Of course, the similarities and differences between these various shi must be determined with more empirical grounding in future research, but we may provisionally theorize that they shared the same overall function of increasing the centripetal pull of the Zhou royal court by providing it with military enclaves in critical regions to augment the infrastructural capacity for local governance and defense already installed there in the form of the regional domains.
Conclusion
In many regards, Western Zhou military organization can be viewed as a microcosm of the broader geopolitical constitution of the Western Zhou state. On the one hand, the Zhou royal court’s preference for the routine use of central and regional troops in tandem highlights the logistical limits of central force projection that necessitated the decentralized geopolitical structure of the Western Zhou state. In addition, the royal court’s increasing reliance on regional military resources to achieve its strategic objectives, especially in the ninth and eighth centuries BCE, reflects the gradual waning of royal authority over time. On the other hand, that mixed central-regional army coalitions were always led by centrally appointed officials and that the royal court was able to maintain direct control over military outposts in certain frontier regions underscores the high level of hierarchical order and political authority the Zhou king was nevertheless able to command. Tellingly, though this centralized military command structure persisted until the end of the Western Zhou period, it was the loss of royal military power following the catastrophe of 771 BCE that presaged the long decline of the Zhou royal house’s preeminence in China over the course of the ensuing Eastern Zhou period.
This study has examined the organization and application of Western Zhou military power especially in the context of long-term regional governance by investigating the operation and role of regional military bases administered by the Zhou royal court. As demonstrated through the analysis of the inscriptional and archaeological evidence for Qi shi in northern Shandong, such regional garrisons were instrumental for extending the range of Zhou political control and logistical reach across the vast landscapes under Zhou dominion. These military enclaves thus formed an important component of Western Zhou geopolitical strategy, effectively acting as a connective bridge between the Zhou royal court and the regional domains and facilitating the coordination of central and regional military resources for the defense of the Western Zhou state.
