Bono state

The Bono State, also known as Bonoman, was a medieval Akan kingdom founded by the Bono people in what is now central Ghana, emerging as one of the earliest centralized polities among Akan groups between the 11th and 13th centuries based on archaeological evidence and oral traditions.^[1]^[2] Centered around the capital of Bono Manso, the kingdom prospered through control of gold production and trade routes linking forest-zone resources to Sahelian markets via the Dyula trading center of Begho (Bighu), which drew Muslim merchants from the Mali Empire and fostered economic and cultural exchanges.^[3] Its hierarchical society featured a divine kingship system with paramilitary divisions, matrilineal inheritance, and artisanal specialization in goldworking, textiles, and pottery, as evidenced by excavations revealing imported glass beads and local terracotta artifacts indicative of trans-Saharan influences.^[2] The Bono State's influence extended to proto-Akan migrations and state formation, but it declined amid internal divisions and external pressures, culminating in conquest by the rising Ashanti Empire around 1723, after which remnants reestablished as the Techiman-Bono kingdom.^[4] Scholarly reconstructions rely heavily on oral histories cross-verified with limited archaeological data, as primary written records are scarce and postdate the kingdom's peak, underscoring debates over precise chronologies derived from radiocarbon dating and trade goods.^[5]

Geography and Demography

Location and Physical Setting

The Bono State occupied a strategic position in central Ghana, corresponding to the modern Bono and Bono East regions, with its core territories extending along the forest-savanna transition zone south of the Black Volta River.^[6] Its ancient capital, Bono Manso, was situated in the Nkoranza North District of present-day Bono East Region, approximately at an average elevation of 360 meters amid undulating terrain.^[7]^[8] This physical setting featured woodland savanna landscapes interspersed with gallery forests along watercourses, providing a mosaic of ecosystems conducive to mixed agriculture, including yams, grains, and livestock rearing.^[6] The region's alluvial soils and proximity to gold-bearing streams, particularly in the vicinity of Bono Manso, supported placer mining operations that underpinned the state's early prosperity and trans-Saharan trade connections.^[9] Rivers such as the Black Volta marked its northern boundary, aiding seasonal flooding for fertile floodplains while posing occasional flood risks.^[10] The transitional ecology also exposed the state to influences from both southern forest trade networks and northern savanna migrations, shaping its demographic and economic dynamics.^[6]

Population and Ethnic Composition

The Bono State, also known as Bonoman, was predominantly inhabited by the Bono people, a matrilineal subgroup of the Akan ethnic cluster who spoke Bono Twi, a dialect of the Twi language within the broader Akan linguistic family.^[11] These communities formed the core demographic, with settlements exhibiting cultural and social structures characteristic of Akan kinship systems, including matrilineal descent and centralized chieftaincy.^[12] Precise population figures for the state as a whole remain elusive due to limited pre-colonial records, but urban centers offer indicative estimates. Begho, the principal trading hub, supported a population likely exceeding 10,000 residents by the 15th century, making it one of the larger southern West African cities upon European contact around 1471.^[13] Comparable assessments place Begho's peak at approximately 12,000 inhabitants, reflecting its role as a nexus for gold and kola nut commerce.^[14] While the state's society was fundamentally homogeneous in its Akan cultural framework—evident in shared governance, religious practices, and artisanal traditions—urban areas like Begho incorporated transient merchant communities. These included Muslim traders (often Wangara or Hausa) in designated Kramo quarters, alongside local Bono and other Akan subgroups such as the Nyarko, though such elements did not alter the dominant ethnic composition.^[11] This structure underscores Bonoman's function as an Akan polity oriented toward internal cohesion rather than cosmopolitan diversity.

Origins and Indigenous Development

Pre-State Foundations

The pre-state foundations of the Bono State encompassed the dispersed settlements and cultural practices of the Bono people, an Akan subgroup, in the savanna-forest transition zone of central Ghana prior to centralized political organization. These foundations involved matrilineal kinship networks, subsistence agriculture focused on yams and cereals, and early exploitation of local resources like iron ore and alluvial gold, which supported population growth and social complexity in village clusters. Archaeological data from regional sites indicate human activity in the broader area from the first millennium AD, with technological continuity in iron smelting and pottery production evidencing indigenous adaptation rather than abrupt external impositions.^[15] Settlement intensification at proto-urban loci like Bono-Manso is marked by radiocarbon dates commencing around 1297 AD, revealing communities with locally produced ceramics, iron tools, and evidence of inter-regional exchange in beads and metals, laying the economic groundwork for later statehood. Oral traditions preserved among Bono elders describe foundational clans tracing to spiritual figures and early leaders at sites such as Amuowi near Nkoranza, potentially reflecting fragmented chiefdoms that coalesced amid growing trade opportunities in the 14th century. However, claims in some traditions of northern migrations—such as from the medieval Ghana Empire—remain unsubstantiated by material or linguistic records, which instead affirm long-term local emergence of Akan cultural elements including Twi dialects and clan-based governance.^[16]^[15] This pre-state phase transitioned into formal polity formation circa 1420, as kinship hierarchies formalized amid external commercial pressures from Dyula traders, yet the core societal resilience derived from these autonomous, resource-exploiting communities.^[16]

Archaeological Evidence of Local Emergence

Archaeological investigations at Bono Manso, the ancient capital of the Bono state located in present-day Ghana's Bono East Region, provide primary evidence for the indigenous development of early Akan urbanism. Excavations conducted by Kwaku Effah-Gyamfi between 1970 and 1979 uncovered stratified settlement layers spanning from the late 12th century CE to the mid-18th century CE, revealing a planned urban layout with residential mounds, refuse heaps, and evidence of dense habitation estimated at around 500 structures.^[17]^[18] Radiocarbon dating from these layers, including seven calibrated samples ranging from 1297 CE to 1630 CE, corroborates the site's longevity and gradual intensification of occupation without abrupt discontinuities suggestive of external imposition.^[15] Material culture from Bono Manso emphasizes local technological continuity, particularly in ceramics and metallurgy. Dominant pottery assemblages, classified as Bono Ware phases, feature rouletted and red-slipped vessels with motifs consistent with broader regional Iron Age traditions predating state formation, indicating endogenous stylistic evolution rather than imported influences.^[19] Iron artifacts, including slag and smelting furnaces, demonstrate advanced local pyrotechnology; a furnace at nearby Bewo (Atwetwebooso) yielded a radiocarbon date of 180 ± 75 CE, while similar features at Bono Manso itself align with practices established by the 3rd century CE in the surrounding savanna-forest transition zone.^[20] These findings, cross-verified through test pits and survey transects, show no predominance of foreign ceramic or metallurgical techniques that would imply migratory elite dominance. Supplementary evidence from peripheral sites reinforces the pattern of local emergence. At Amuowi, identified in oral traditions as a foundational settlement near Nkoranza, limited excavations uncovered early occupation layers with radiocarbon dates around 710 ± 95 CE and 980 ± 85 CE, featuring indigenous iron-working residues and pottery linking to pre-urban Bono phases.^[21] Kranka Dada, a contemporaneous mound site adjacent to Bono Manso, yielded faunal remains, grinding stones, and ritual deposits indicative of self-sustaining agrarian communities evolving into hierarchical structures without evidence of sudden cultural rupture.^[22] Collectively, this archaeological corpus—prioritizing empirical stratigraphy over potentially mythologized oral accounts—supports the Bono state's roots in autonomous regional adaptations of Iron Age technologies and subsistence strategies, predating documented trans-Saharan trade networks.^[23]

Rise and Political Expansion

Formation of the Core State

The core Bono state, also known as Bonoman, coalesced in the early 15th century around the settlement of Bono-Manso in the savanna-forest transition zone of present-day central Ghana. Reassessments of oral regnal chronologies and queenmother successions indicate formation circa 1420 CE, marking the transition from dispersed Akan settlements to a centralized polity capable of administering tribute and defense.^[16] ^[24] This dating supersedes earlier estimates, such as Eva Meyerowitz's unsupported claim of 1295 CE, which lacked corroboration from archaeological or documentary evidence.^[25] Archaeological excavations at Bono-Manso, conducted by Kwaku Effah-Gyamfi, uncover phased pottery sequences (Bono Ware Phases I-III) and structural remains evidencing urban planning, including walled enclosures and elite residences, consistent with the emergence of kingship as a unifying institution among Bono Akan clans.^[19] These findings align with oral accounts of migrations from northern or eastern origins, where proto-Akan groups exploited gold deposits and alluvial resources to generate surpluses that underpinned hierarchical authority. Effah-Gyamfi's analysis posits Bono-Manso as an early hub of Akan urbanism, predating but influencing later states like Asante, though debates persist on whether pre-15th-century occupations represent proto-state complexity or mere villages.^[26] The state's consolidation was propelled by integration with the nearby Begho trade entrepôt, where Dyula merchants from the Mali Empire exchanged savanna goods for forest gold and kola, fostering economic interdependence that reinforced Bono rulers' control over tribute networks and military levies. By the late 15th century, this core had expanded to encompass tributary villages, establishing Bono as a foundational Akan polity amid regional migrations and competition.^[27]

Major Urban Centers and Settlements

Bono-Manso served as the capital of the Bono state, emerging as a prominent urban center in the northern forest-savanna transition zone of present-day Ghana by the 14th century. As the political and cultural heart of the kingdom, it functioned as a hub for Akan civilization, with growth tied to gold exploitation and centralized authority, evidenced by archaeological findings of structured settlements and iron production facilities.^[28] The site's development reflects early state formation, with evidence of larger town emergence around 700 BP, including defensive features and ritual spaces that supported kingship rituals.^[29] Begho, located south of the Black Volta River, ranked as the Bono state's foremost commercial settlement, established around the 11th century and peaking as the largest interior town in the Gold Coast region by 1471 upon Portuguese arrival. Archaeological excavations from 1970 to 1979 uncovered multi-ethnic quarters, including Akan, Wangara trader, and Grusi artisan zones, with artifacts indicating specialized crafts like pottery and metalworking; population estimates place it above 10,000 inhabitants, underscoring its role in gold and kola nut exchange.^[30] This segregation facilitated trade efficiency but limited non-Akan political influence, aligning with Bono governance patterns.^[29] Additional settlements, such as those around Takyiman (modern Techiman) and Nkoransa, formed secondary urban nodes within the Bono core, supporting agricultural surplus and tribute flows to the capital; these exhibited comparable planning with walled compounds and markets, though archaeological data remains sparser than for Bono-Manso or Begho.^[31] Overall, Bono urbanism emphasized fortified towns with sacred enclosures, enabling control over forest resources and caravan routes from the 13th to 17th centuries.^[32]

Kingship and Centralized Authority

The Bono state, as one of the earliest Akan polities, developed a centralized kingship system centered on the Omanhene (king), who exercised authority over territorial administration, economic resources, and military affairs from the kingdom's capital at Bono-Manso.^[33] This structure emerged around the mid-15th century, with the king supported by a royal household that coordinated gold mining and trade, key drivers of state power and expansion.^[33] Rulers such as Obunumankoma (c. 1450–1475) and ʿAlī Kwame (c. 1550–1560) actively shaped this authority by adopting mining techniques from western Sudanese influences, enhancing royal control over production and distribution.^[33] Later, Owusu Aduam (c. 1650) reorganized the gold industry, further consolidating centralized oversight amid interactions with Muslim traders, many of whom influenced royal conversions to Islam after 1450.^[33] Centralized authority manifested through a hierarchical chain of command, extending from the Omanhene to subordinate chiefs who governed villages and towns, backed by councils of elders for deliberation on disputes and policy. This stratification enabled the integration of conquered or allied groups, as seen in the enstoolment of figures like Bonohene Berempon Katakyira in 1564, marking formal installation rituals that reinforced monarchical legitimacy.^[34] The king's role extended to religious functions, positioning the throne as a mediator between the polity and spiritual forces, though evidence remains primarily oral and tied to Akan traditions of divine kingship. Economic centralization, particularly in gold and kola nut trade routes to Gonja and beyond, underpinned this system, with royal appointees managing tribute and labor allocation to sustain loyalty and military capacity.^[33] Despite its robustness, the kingship faced challenges from internal fragmentation and external threats, culminating in subjugation by the Asante Empire under Opoku Ware in 1722–1723, which dismantled Bono's independent centralized structure.^[33] Pre-colonial records, drawn from European accounts and local chronologies, indicate that while the system promoted stability through matrilineal succession—favoring royal lineages via queen mothers—it was not immune to disputes over enstoolment, as evidenced by varying dates for rulers in Gonja-influenced manuscripts.^[34] This Akan-derived model of kingship, pioneered by Bono among forest states, influenced subsequent polities by demonstrating how resource control could forge enduring centralized authority amid decentralized kinship networks.

Administrative Hierarchy and Kinship Systems

The Bono state's administrative structure exemplified the early Akan model of hierarchical chieftaincy, centered on a paramount ruler known as the Omanhene, who held ultimate authority over political, judicial, and military affairs from the capital at Bono Manso.^[35] This king was advised by a council of elders (Nananom) and divisional chiefs representing territorial units, ensuring decentralized execution of central policies while maintaining loyalty through oaths and tribute systems.^[36] The queen mother (Ohemaa) held significant influence, particularly in selecting successors from eligible royal kin, reflecting the integration of gender roles in governance.^[37] Subordinate ranks included Kontihene (chief of war and administration) and wing chiefs such as Nifahene (right wing) and Benkumhene (left wing), who managed local defense, taxation, and dispute resolution in conquered or allied territories.^[36] This tiered system facilitated expansion and control over trade routes, with chiefs appointed from matrilineal lineages to bind administrative roles to kinship obligations.^[35] Kinship organization in Bonoman adhered to the Akan matrilineal (abusuapanyin) system, where descent, inheritance, and succession traced through the mother's line, prioritizing lineage continuity over paternal ties.^[37] Society coalesced around eight exogamous clans (abusua), with the royal house typically affiliated to one such as Oyoko or Aduana, dictating eligibility for chieftaincy and property rights.^[27] This structure reinforced social cohesion, as extended matrilineages (ntoro for paternal influence in some rituals but secondary) handled communal labor, marriage alliances, and conflict mediation, adapting Crow-like classificatory kinship to integrate slaves and migrants into peripheral roles.^[37]

Economy and Trade Networks

Agriculture and Local Production

Agriculture in the Bono state centered on subsistence farming in the savanna-forest transition zone, supporting dense settlements at sites like Bono-Manso and Begho through continuous cultivation evident in archaeological records dating back centuries before significant external trade influences. Slash-and-burn methods were prevalent, involving the clearing of vegetation by fire to prepare fertile plots for short-term use before soil exhaustion prompted relocation to new areas, a practice adapted to the region's nutrient-poor soils and variable rainfall. This system allowed for mixed cropping that maximized yields from limited land, underpinning the state's demographic growth and economic base independent of imported staples.^[18]^[38] Staple crops included root vegetables such as yams—especially the puna yam (Dioscorea bulbifera)—and grains like sorghum and pearl millet, which were suited to the local climate and provided reliable caloric sources for the population. Oil palm (Elaeis guineensis) was a key multipurpose crop, yielding oil for cooking and preservation, kernels for further processing, and fermented sap for palm wine, contributing to both daily sustenance and ritual uses. These agricultural outputs not only met local demands but also facilitated surplus production for exchange in regional networks, with evidence of high population densities at Bono-Manso indicating effective land management despite the challenges of shifting cultivation. Local production extended beyond field crops to include agroforestry elements like kola nut cultivation in shaded groves, which complemented farming by providing cash-like commodities for trade without depleting arable land. Women dominated agricultural labor, handling tasks from land preparation to post-harvest processing and market sales, a division of labor that integrated farming with household crafts such as pottery and weaving for mats or baskets used in storage and transport. Archaeological findings from sites near Bono-Manso confirm iron tools for tillage and smelting residues alongside crop remains, highlighting how local metallurgy enhanced agricultural efficiency through hoes and machetes tailored to the terrain. This self-reliant production model sustained the Bono state's autonomy until pressures from expanding neighbors disrupted it in the late 17th century.^[39]^[40]

Role of Begho in Regional Commerce

Begho functioned as the central commercial entrepôt of the Bono state, bridging trade between the northern savanna zones and southern forest regions from approximately the 11th to the 18th centuries. Positioned along critical caravan routes, including the north-south path from Djénné through Bolo, Doulasso, and Kong, as well as the east-west Bondoukou-Begho corridor, it enabled the flow of goods across West Africa.^[41] This connectivity positioned Begho as a nexus for regional exchange, where northern imports like salt, leather, and North African textiles were bartered for southern exports such as gold, kola nuts, and later slaves.^[42] Gold, sourced from nearby Bono goldfields, emerged as the dominant commodity by the mid-14th century, fueling economic expansion and attracting merchants from distant networks linked to trans-Saharan routes. The town's cosmopolitan character, evidenced by distinct quarters for Akan locals (Nyantakyi) and Mande Muslim traders (Kramo or Wangara), underscored its role in fostering multi-ethnic commerce. These Wangara intermediaries, originating from Sahelian polities, introduced Islamic influences and northern manufactures, while local industries—indicated by abundant iron slag from smelting—produced tools and weapons to support trade logistics.^[42] Archaeological findings from 1970–1979 excavations, including imported glass beads, smoking pipes, and ceramics, confirm Begho's status as the largest interior settlement in the Gold Coast region by 1471, when Portuguese explorers first encountered West African coastal trade extensions.^[30] This infrastructure not only enriched Bono's polity but also disseminated crafts like weaving and dyeing southward, integrating the state into broader West African economic circuits. Begho's decline in the early 18th century, amid Ashanti military pressures, disrupted these networks, shifting commerce toward coastal European outposts, yet its legacy persisted in oral traditions and successor Akan trade patterns.^[43] Empirical evidence from site surveys prioritizes this localized, route-dependent model over speculative long-distance migrations, emphasizing Begho's organic emergence as a commerce facilitator driven by resource complementarity rather than external imposition.^[30]

Culture, Religion, and Technology

Spiritual Beliefs and Practices

The Bono state's spiritual framework was rooted in traditional Akan cosmology, emphasizing a supreme creator deity known as Nyame (or Onyankopon), who was omnipotent and omniscient but distant from daily human affairs, alongside intermediary lesser deities (abosom) and ancestral spirits (nananom nsamanfo).^[44] These beliefs positioned the Bono as a cultural progenitor among Akan groups, with spiritual practices integrating matrilineal kinship, ritual veneration, and environmental sacrality to maintain cosmic harmony and communal prosperity.^[44] Central to Bono practices were the abosom, localized deities manifesting through natural features like rivers and forests, with Tano (or Ta Kora), the river god of the Tano River, holding paramount status as the "king of obosom" in the Bono-Manso and Techiman regions. Tano was invoked for protection in warfare, revelation of truths, fertility blessings, and safeguarding the kingdom from spiritual threats, often through sacrifices and consultations at sacred river shrines such as Tanoboase, where oral traditions link the deity to the Bono's foundational emergence from the Amowi cave around the 12th-13th centuries.^[45]^[46] Ancestral veneration complemented this, with nananom nsamanfo regarded as active intermediaries influencing the living; they were honored via blackened stools (aponnwa or aponsuani), symbolic seats blackened with ritual substances like eggs and shea butter, embodying deceased rulers' spirits and serving as conduits for guidance, dispute resolution, and protection.^[47]^[44] Rituals reinforced these beliefs, including periodic purification of ancestral stools during festivals—conducted every 40 days or annually—to appease spirits and avert misfortune, alongside offerings to abosom for agricultural success and trade prosperity, reflecting the Bono's role as a commercial hub where spiritual efficacy was tied to economic vitality.^[44] Earthly reverence extended to Asaase Yaa, the mother earth deity, prohibiting practices like lying or spilling blood on the ground to preserve her sanctity, underscoring a causal link between moral conduct, environmental stewardship, and spiritual favor.^[45] These elements formed a holistic system where spiritual adherence underpinned kingship legitimacy and social order, with priests (okomfo) mediating between realms through divination and trance-induced prophecies.^[47]

Material Culture and Innovations

Archaeological excavations in the Bono state, particularly at its capital Bono-Manso and associated sites like Kranka Dada, reveal a material culture dominated by locally produced pottery, with evidence of specialized manufacturing techniques. Pottery sherds constitute the most abundant artifacts, featuring local wares characterized by everted rim jars (mean diameter 20-22 cm), hand-smoothed surfaces (79.4% of analyzed sherds), and decorations such as grooves (49.6%), twisted cord roulette (13.9%), and, in later phases post-1543 CE, maize cob impressions indicating New World crop introductions via Atlantic trade.^[18] Painted pottery, concentrated in early phases dated 1250-1450 CE, included red and brown paint bands alongside imported styles akin to those from Begho and Silima, reflecting regional exchange networks.^[21] Ceramic firing features, such as one dated 1465 ± 32 CE containing 59 vessels (36 decorated), demonstrate on-site production innovations, likely by women as part-time specialists trading vessels for foodstuffs.^[18] Metallurgy formed a cornerstone of Bono material culture, supporting the state's gold trade dominance, with artifacts evidencing both iron and non-ferrous working. Iron slag mounds (0.75-1.2 m high), tuyeres, and utilitarian items like arrow points and knives indicate local blacksmithing, often hereditary and conducted away from settlements to preserve techniques.^[18] Brass and copper objects, though lower in frequency (e.g., 55 items in phases II-III), included bracelet fragments, possible coins and projectiles, and ritual vessels like Ayaa Dasuo basins with Mamluk Arabic inscriptions, repurposed from trans-Saharan imports into local ceremonies.^[18] Gold extraction innovations encompassed vertical shafts sunk into bedrock for mining and panning, with crafting restricted to royal artisans, enabling standardized trade measures that influenced later Akan gold dust weighing systems.^[18] Other artifacts highlight diverse crafts and trade integrations, including grindstones, perforated pottery discs for sieves, carved ivory, and spindle whorls (15 recovered) for textile production, alongside imported glass beads, cowrie shells, and European ceramics post-1482 CE.^[15]^[18] Smoking pipes (231 at Kranka Dada, earliest 1568 CE) adapted to tobacco introduction, featuring new round and square bases, underscore technological adaptations to global exchanges. Sites like Sabule yielded iron bracelets, arrowheads, and slag alongside Gonja Dimbia Ware pottery (85% twisted cord roulette-decorated), dated 1321-1615 CE, affirming Bono's role in broader savanna-forest cultural interactions through shared ceramic traditions.^[15] These elements, spanning 1323-1621 CE at key sites, illustrate a pragmatic, trade-oriented material culture with incremental innovations in production and adaptation rather than radical inventions.^[18]

Decline and Fragmentation

Internal and External Pressures

The decline of the Bono state was precipitated by a confluence of internal pressures that undermined its cohesion and administrative efficacy. Succession disputes among ruling lineages frequently erupted into power struggles, eroding centralized authority and diverting resources from defense and trade maintenance.^[48] Excessive taxation imposed by elites to sustain courtly expenditures exacerbated social tensions, while misconduct among the nobility, including corruption and factionalism, further destabilized governance structures.^[48] Archaeological evidence from Bono Manso reveals signs of demographic decline in the 17th century, likely linked to internal factors such as resource depletion and population dispersal amid agricultural stress.^[18] Externally, the Bono state faced mounting threats from expansionist neighbors that disrupted its economic foundations. In 1595, the Gonja kingdom launched a military conquest that defeated the Great Bono lineage, fragmenting territorial control and interrupting northern trade links.^[48] By the early 18th century, rising Akan polities, particularly Denkyira and the emergent Asante Empire, imposed competitive pressures through raids and blockades on gold and kola trade routes, diminishing Bono's commercial dominance.^[49] The Asante invasion of Bono Manso in 1723 culminated in its sack, accelerating fragmentation as survivors relocated southward to sites like Techiman, marking the effective end of Bono hegemony.^[48] Broader environmental stressors, including probable droughts in the 17th century, compounded these invasions by prompting economic restructuring and migration outflows.^[42]

Transition to Successor Polities

The Bono state's decline, accelerated by its defeat at the hands of the Gonja Kingdom in 1595, led to territorial fragmentation and the erosion of centralized authority, creating opportunities for emergent Akan polities to expand into former Bono domains.^[48] Internal power struggles between ruling lineages further weakened cohesion, shifting control southward to states like Denkyira, which capitalized on Bono's vacuum through conquests and trade dominance in the late 15th to 17th centuries.^[48] By the early 18th century, succession disputes, heavy taxation, and governance failures under Bonohene Ameyaw Kwakye compounded these pressures, culminating in Asante invasions of Bono-Manso in 1722–1723 that prompted the capital's abandonment by mid-century.^[49] Takyiman (Techiman) emerged as the principal successor polity, relocating the Bono core and maintaining continuity in chieftaincy institutions, oral rituals, and festivals like Apoɔ, while Asante annexed nine Bono villages (e.g., Tuobodom, Tanoboase) for tribute and seized the royal treasury to bolster its own administration.^[49] Population dispersal from sites like Bono-Manso and Begho integrated Bono elites and artisans into broader Akan networks, influencing Denkyira's military structure before its own defeat by Asante in 1701 and contributing cultural precedents—such as kinship hierarchies—to Asante's confederation model.^[48]^[49] Remnant Bono entities, including Nkoranza and Wenchi, persisted as semi-autonomous units under Asante overlordship until the late 19th century, when British colonial interventions in 1877–1902 prompted further migrations, such as to Gyaman, reshaping local polities into the modern Bono-Kyempim federation by 1951.^[49]

Historiography, Myths, and Controversies

Colonial-Era Narratives and Fabrications

During the colonial period, European administrators and historians often constructed narratives attributing the origins of the Bono state (Bonoman) to migrations from the ancient Ghana Empire (Wagadu), centered in the western Sahel around modern southeastern Mauritania and southwestern Mali, positing a southward exodus of proto-Akan groups around the 11th-12th centuries CE due to factors like Almoravid invasions or dynastic collapse.^[48] This diffusionist framework, influenced by 19th- and early 20th-century scholarship emphasizing external stimuli for African state formation, lacked empirical support from linguistics, genetics, or archaeology, which instead indicate indigenous development of Bono society in the forest-savanna ecotone through gradual sedentism and trade integration by the 13th-14th centuries CE.^[50] Such accounts served to align West African polities with Sahelian "empires" in a linear civilizational progression, downplaying local agency amid broader Eurocentric historiographies that questioned sub-Saharan capacities for complex governance without northern infusion.^[51] Another fabrication involved overattributing Bonoman's gold-mining and trading prowess to Manden (Mali Empire) cultural diffusion via Dyula merchants, portraying them as exogenous Islamized founders who introduced advanced techniques and state structures to passive Akan communities at sites like Begho.^[52] Colonial-era ethnographies, drawing on selective oral interpolations and traveler accounts from the 17th-19th centuries, amplified this to explain the kingdom's urbanism—evidenced by Bono Manso's planned settlements spanning over 500 structures by the 15th century— as derivative of Sahelian models rather than evolving from local Volta Basin innovations in hydraulic mining and kola-salt exchange networks predating Manden contacts.^[19] Archaeological data from Bono Manso and adjacent sites reveal continuity in pottery, ironworking, and settlement patterns from the 11th century, contradicting mass-migration scenarios and highlighting endogenous adaptations to ecological niches.^[23] British colonial historiography further distorted inter-Akan dynamics by privileging Asante narratives, which retroactively depicted Bonoman as a fragmented precursor or tributary, thereby marginalizing Bono's role as the earliest centralized Akan polity with its own paramountcy and regalia systems by circa 1300 CE.^[49] This selective amplification, evident in administrative reports from the early 1900s Gold Coast Colony, stemmed from alliances with Asante elites post-1900 conquest, fostering myths of Bono subordination to justify indirect rule hierarchies and obscure the kingdom's independent florescence in regional commerce before Asante expansion in the 1670s.^[53] These fabrications persisted in textbooks and policy until mid-20th-century archaeological reassessments, underscoring how colonial source selection—favoring literate northern chronicles over Akan oral corpora—embedded biases that conflated trade influences with foundational ethnogenesis.

Debunking Migration Theories

Migration theories positing the Bono people's origins in a southward movement from the Sahel, Sahara, or the ancient Ghana Empire—often dated to the 13th to 15th centuries—rely primarily on selective interpretations of oral narratives and assumptions of cultural diffusion from northern polities, but these lack substantiation from physical evidence.^[48] Such accounts, including legendary ties to regions like Nubia or even Egypt, appear in some traditional histories but reflect mythological embellishments rather than verifiable population displacements, as they conflate symbolic journeys with literal migrations.^[54] Archaeological data from Bono Manso, the state's historic capital near modern Techiman, demonstrate settlement and iron smelting activities with roots in local technological traditions predating proposed migration timelines, indicating endogenous cultural evolution rather than abrupt external imposition. Excavations reveal stratified deposits showing continuity in pottery styles, metallurgical practices, and urban morphology from the 14th century onward, without artifacts signaling a sudden influx of northern-derived material culture.^[23] This evidence aligns with broader findings at associated sites like Begho, where trade-oriented developments emerged from pre-existing regional networks, refuting models of Bono society as a mere transplant from Sahelian empires.^[55] Oral traditions documented among the Bono, particularly those of Techiman (Takyiman), consistently assert autochthonous emergence from subterranean sites such as the Amowi cave, portraying the people as "first-born" from the land itself—a motif underscoring indigenous primacy over migratory advent. These accounts, cross-verified with archaeological sequences linking early habitations (Amuowi I and II) to Bono Manso, prioritize causal continuity in local ecology and resource exploitation, such as gold and kola, as drivers of state formation rather than exogenous population waves.^[23]^[54] Critiques of migration-centric frameworks, including Ivor Wilks's "Big Bang" model of rapid Akan coalescence via northern influences, highlight their overreliance on unverified diffusionism while ignoring stratigraphic data; archaeologists like Peter and Ama Shinnie emphasized that iron-age foundations in the forest-savanna transition zone evolved indigenously by the early medieval period, rendering large-scale Sahel migrations unnecessary for explaining Bono's political and economic sophistication.^[55] Linguistic divergence among Akan dialects further supports in-situ adaptation, with no abrupt shifts indicative of mass assimilation from unrelated northern tongues. Empirical reassessment thus privileges gradual, adaptive processes rooted in the Bono heartland over speculative external provenances, which often stem from historiographic biases favoring dramatic narratives.

Empirical Reassessments from Archaeology and Oral Traditions

Archaeological excavations at Bono Manso, the ancient capital of the Bono state, have uncovered stratified deposits containing iron slag, locally produced smoked pottery, and fragments of imported glass beads, indicating sustained occupation and metallurgical activity from approximately the 11th to the 18th century CE.^[56] ^[21] These artifacts demonstrate early iron smelting capabilities and craft specialization, with radiocarbon dates aligning phases of site development to the medieval period, predating widespread European influence.^[57] Test pits and surveys guided by local knowledge have further revealed settlement mounds and refuse heaps consistent with a nucleated urban center supporting several thousand inhabitants at its peak.^[58] Oral traditions of the Takyiman-Bono, preserved through chiefly lineages and praise-singing performances, describe the state's origins as evolving from small hunter-gatherer and farming communities along the forest-savanna fringe, with the founding of Bono Manso attributed to leaders like Obuomankoma around the late 13th century.^[59] These accounts, which emphasize indigenous consolidation rather than distant migrations, have been corroborated by the distribution of archaeological sites matching described ancestral villages and ritual landscapes, such as cave systems linked to emergence myths near Fiema.^[60] Integration of such traditions with fieldwork has refined chronologies, revealing continuity in material culture like distinctive Bono pottery forms that persist in descendant Akan groups.^[23] These empirical sources reassess earlier historiographical emphases on external derivations or late formations by evidencing autonomous technological and social complexity, with iron production and trade infrastructure indicating Bono's pivotal role in regional networks by the 14th century.^[61] Findings challenge dismissals of oral evidence as mythic, instead validating it through cross-verification, though limited excavation scale—due to site looting and modern overbuild—necessitates caution in extrapolating population estimates or precise state boundaries.^[62] Peer-reviewed analyses underscore that such data privileges local agency over diffusionist models, highlighting Bono's contributions to Akan ethnogenesis via verifiable artifact assemblages rather than unsubstantiated colonial interpolations.^[63]

The Bono state, emerging around 1420 in the forest-savanna transition zone of present-day Ghana, served as a foundational model for Akan political organization, with its centralized chieftaincy system—featuring matrilineal succession and a paramount ruler advised by a queen mother—influencing successor polities such as Denkyira and Asante.^[16] Archaeological excavations at Bono-Manso reveal an urban center with planned layouts, craft specialization in goldworking and textiles, and trade infrastructure that supported administrative hierarchies later replicated in expanding Akan kingdoms.^[23] Oral traditions preserved among Bono descendants, corroborated by linguistic evidence of shared Akan dialects, describe migrations of clans from Bono-Manso during periods of internal strife or resource competition, seeding the establishment of states like Wassa and Akyem by the mid-17th century.^[23] Bono's dominance in trans-Saharan gold trade, peaking from the 15th to 17th centuries, disseminated institutional templates for taxation, military mobilization, and oath-based alliances that nascent Akan groups adopted to consolidate power amid ecological pressures in southern forest zones.^[16] For instance, the ntumguru (stool house) ritual complex, central to Bono governance for legitimizing authority through ancestral veneration, appears in the foundational myths of Asante's Oyoko clan, which traces its paramountcy rituals to Bono exemplars around 1700.^[54] This diffusion is evidenced by artifact distributions, such as similar gold weights and terracotta figurines found at Bono-Manso and early Denkyira sites, indicating cultural emulation rather than conquest.^[23] While oral accounts often idealize Bono as the singular "cradle" of Akan statehood, empirical reassessments emphasize its catalytic role in a polycentric process, where Bono's economic surplus enabled experimentation with scalable governance that other proto-Akan settlements adapted locally, fostering resilience against 17th-century disruptions like Dyula raids.^[16] Scholarly analyses of Bono's seven matrilineal clans highlight how their migratory branches carried administrative precedents, contributing to the confederative structures in polities like Akwamu by the late 1600s.^[35] This influence persisted into the 18th century, as Bono remnants integrated into Asante, embedding precedents for fiscal centralization that underpinned its imperial expansion.^[54]

Contributions to Broader Ghanaian History

The Bono state, centered at Bono Manso, established foundational economic patterns in Ghanaian history by emerging as a primary hub for gold production and trade between the 14th and 19th centuries, linking savanna traders from the Mande of the Niger Bend and Mossi of Wagadugu with forest-zone resources. This commerce, predating the Atlantic slave trade's dominance in the late 17th century, generated substantial wealth that underpinned Akan state formation across central and southern Ghana, enabling the acquisition of firearms and reinforcing socio-political hierarchies, such as symbolic regalia denoting authority.^[64] As one of the earliest centralized Akan polities, dating to the 11th-12th centuries, Bono provided a template for governance structures that influenced successor kingdoms, including Denkyira and Asante, through matrilineal succession and hierarchical chieftaincy systems disseminated via migrations from its core territories. These outflows of populations, driven by the kingdom's prosperity in gold and kola nut exchanges, populated and organized much of modern Ghana's Akan heartlands, fostering political consolidation amid inter-state competitions.^[65] Bono's role extended to cultural dissemination, with practices in craftsmanship—such as gold-weight standardization for trade—and administrative traditions serving as precursors to broader Akan innovations that shaped Ghana's pre-colonial ethnic mosaic and enduring regional identities. Archaeological evidence from sites like Bono Manso corroborates oral accounts of its stability and influence, countering later narratives that marginalized its precedence in favor of Asante dominance.^[19]
