Kubrat

![Kubrat and his sons depiction](./assets/Giudjenov_Kubrat_and_his_sons_cropped Kubrat (died c. 665), ruler of the Dulo clan, was the Bulgar leader who unified disparate tribes including the Onogurs and established the confederation of Old Great Bulgaria around 632 in the Pontic-Caspian steppes, particularly the region of the Lower Dnieper.^[1] His state, also termed Patria Onoguria by Byzantine sources, achieved independence from Avar overlordship and maintained a precarious autonomy against emerging Khazar threats through military prowess and strategic alliances, notably with the Byzantine Empire.^[1] Primary accounts from Byzantine chroniclers such as Theophanes Confessor detail how Kubrat's death precipitated the fragmentation of his realm, as his sons— including Batbayan, Kotrag, and Asparuh—led migrations that seeded successor Bulgar polities like Volga Bulgaria and the Danube Bulgarian Khanate.^[1] Archaeological evidence, including treasures attributed to his era, underscores the material wealth and cultural synthesis of his confederation, blending steppe nomadic traditions with influences from neighboring powers.^[2] Kubrat's reign represents a pivotal moment in Bulgar ethnogenesis, marking the consolidation of proto-Bulgar identity amid the volatile tribal dynamics of the Eurasian steppes, though sustained by fragile unity rather than enduring institutions.^[1] While Byzantine records portray him as a formidable yet transient power, later national historiographies may overemphasize continuity with modern Bulgarian statehood, diverging from the empirical dispersal evident in contemporary accounts.^[1]

Origins and Early Life

Tribal and Familial Background

Kubrat emerged as a leader among the Onogur-Bulgars, a Turkic-speaking nomadic group comprising the Unogundurs or Onogondurs, whose name derives from "Onogur," signifying "ten tribes" in reference to their tribal structure. These Bulgars had migrated from Central Asia to the Pontic-Caspian steppes by the 5th century AD, where they initially fell under the suzerainty of the Avar Khaganate in the 6th century. Primary Byzantine accounts, including those of Theophanes the Confessor, identify Kubrat as the ruler of the "Patria Onogouria," the homeland of the Onogurs north of the Black Sea, encompassing areas around the Sea of Azov and the lower Don River.^[3]^[4] The broader Bulgar confederation included related tribes such as the Kutrigurs and Utigurs, with whom Kubrat forged alliances to form Old Great Bulgaria circa 632 AD, following a successful revolt against Avar domination. Archaeological and historical evidence places their settlements in the region of modern southern Russia and Ukraine, characterized by semi-nomadic pastoralism, warrior elites, and interactions with neighboring Slavs, Khazars, and Byzantines.^[4] Familial details about Kubrat's parentage remain undocumented in contemporary sources like Theophanes or the Chronicle of Fredegar, rendering his immediate ancestry uncertain. Later medieval Bulgarian texts, such as the 9th-century Nominalia of the Bulgarian Khans, designate him as "Kurt" of the Dulo clan, a purportedly ancient ruling lineage among the Bulgars that claimed continuity from earlier steppe empires. This clan affiliation, however, appears in retrospective compilations blending history and legend, including assertions of descent from Avitohol (possibly equated with Attila the Hun) to enhance dynastic legitimacy, a common motif in nomadic genealogies but lacking corroboration from 7th-century records.^[5]^[6]

Upbringing and Byzantine Connections

Kubrat, born circa 605 into the Dulo clan of the Onogur-Bulgars north of the Black Sea, experienced an upbringing amid the shifting alliances of steppe nomads under Avar overlordship. Following the death of his father or predecessor, his maternal uncle Organa served as regent over their tribe, providing initial leadership stability during Kubrat's youth. Historical accounts indicate that around 619, Kubrat was sent to or arrived in Constantinople, the Byzantine capital, possibly as a hostage to secure peace or as part of diplomatic exchanges during Emperor Heraclius's wars against Persia and the Avars.^[7]^[8] In Constantinople, Kubrat resided in the imperial palace for several years, where he was baptized into Orthodox Christianity and received education in Byzantine customs and administration. This period forged enduring personal connections with the court, culminating in Heraclius granting him the prestigious title of patrician—the highest honor below the imperial family—sometime before 632. These ties extended to political support: Kubrat backed Heraclius's widow Martina and her son Heraclonas in their 641 bid against challengers to the throne, actions that underscored his alignment with Byzantine interests.^[9]^[10]^[11] By the 630s, Kubrat returned to the Pontic steppes, leveraging his Byzantine exposure to unify tribes and establish Old Great Bulgaria while maintaining non-aggression pacts with Constantinople, in contrast to conflicts with Khazars and Avars. However, the narrative of his extended palace upbringing draws primarily from later Byzantine chroniclers like John of Nikiu, whose account of a figure named Ketrades has been linked to Kubrat; recent scholarship by historian Shamil Mingazov challenges this identification as a 19th-century interpretive error, suggesting scant direct primary evidence for prolonged residence or baptism under imperial auspices and attributing relations more to pragmatic diplomacy than personal rearing.^[12]^[13]

Rise to Power

Leadership Among Onogurs

Kubrat asserted leadership over the Onogurs, a Turkic-speaking Oghuric tribal confederation in the Pontic-Caspian steppe, in the early seventh century after returning from Byzantine territories where he had been raised. Byzantine chronicler Theophanes the Confessor and Patriarch Nikephoros identified him explicitly as the ruler of the Unogundurs, an alternate designation for the Onogurs, emphasizing his command over this group amid broader nomadic alliances.^[3]^[14] By approximately 632 AD, Kubrat organized the Onogurs to overthrow Avar domination, which had subordinated the tribe since the late sixth century, securing autonomy in the regions around the Sea of Azov and northern Black Sea coast. This revolt capitalized on weakening Avar influence following defeats against the Byzantines and internal fractures, allowing Kubrat to consolidate military and political authority through tribal levies and strategic alliances with neighboring Utigurs and Kutrigurs.^[6]^[15] Under Kubrat's rule, the Onogurs formed the nucleus of a nascent confederation, blending their ten-tribe structure—reflected in the ethnonym "On-Ogur" meaning "ten arrows" or "ten tribes"—with Bulgar elements from the Dulo clan, to which Kubrat belonged. This leadership emphasized martial cohesion and expansion, evidenced by diplomatic ties with Byzantium, including baptism and alliances against common foes like the Persians, though Byzantine sources portray these relations pragmatically rather than ideologically.^[4]^[16]

Unification of Bulgar Tribes

Kubrat, having consolidated power among the Onogur-Bulgars, unified the fragmented Bulgar tribes in the Pontic-Caspian steppe during the early 7th century, forming the confederation known as Old Great Bulgaria. This process involved integrating the Onogurs—his primary base—with the neighboring Utigurs to the east and Kutrigurs to the west, along with smaller associated groups, into a cohesive political entity.^[17]^[6] The unification capitalized on the weakening of Avar influence and Kubrat's diplomatic ties with the Byzantine Empire, forged during his upbringing in Constantinople under Emperor Heraclius.^[6] The confederation's territory extended from the Kuban River in the north Caucasus, across the steppes north of the Black Sea and Sea of Azov, to the Dnieper River, encompassing key settlements like Phanagoria on the Taman Peninsula, which served as the administrative center.^[6]^[16] Byzantine sources, including the Chronicle of Theophanes the Confessor, describe Kubrat as the "king of the Onogundur Huns," reflecting the Onogundur core of his rule while implying the broader tribal alliance he established. This consolidation marked the first major Bulgar state formation, enhancing military and economic capabilities through centralized leadership over nomadic warrior clans.^[4] The exact timing of the unification is placed around 632–635 AD, coinciding with Kubrat's maturation into full authority following the death of his predecessor, likely Organas or Bone.^[16]^[17] Archaeological evidence, such as Bulgar-style burials and artifacts in the region, supports the presence of a unified polity under Kubrat, though primary textual accounts remain limited to Byzantine chroniclers with potential eastern frontier biases.^[15] The alliance's stability relied on Kubrat's personal prestige and oaths of loyalty from tribal leaders, as later evidenced by his deathbed instructions to his sons to maintain unity against external threats like the Khazars.^[6]

Reign and Governance

Establishment of Old Great Bulgaria

Around 632, Ruler Kubrat, leader of the Onogur Bulgars, achieved independence from Avar overlordship and unified disparate Bulgar tribes, including the Kutrigurs and Utigurs, into a confederation known as Old Great Bulgaria.^[4] ^[18] This union formed in the Pontic-Caspian steppes, extending from the Kuban River basin in the east to the Dnieper River in the west, north of the Black Sea and encompassing the Sea of Azov region.^[19] ^[17] Byzantine chronicler Theophanes the Confessor records Kubrat as "king of the Onogundur Huns," noting his alliance with Emperor Heraclius (r. 610–641), who dispatched gifts and priests, facilitating the establishment of Bulgar sovereignty amid the weakening of steppe khaganates.^[6] The confederation's core was the Patria Onoguria, with Phanagoria on the Taman Peninsula serving as the presumed political center, leveraging its strategic position near the Bosporan Kingdom's remnants for trade and defense.^[4] ^[9] This unification capitalized on the collapse of the Western Turkic Khaganate and Avar influence, enabling Kubrat to consolidate military power through tribal alliances rather than direct conquest, as evidenced by the absence of widespread destruction in contemporary archaeological records.^[15] The Nominalia of the Bulgarian Khans attributes to Kubrat a 60-year reign, likely commencing circa 580–590 and extending to his death around 642, underscoring the longevity of his foundational efforts despite the document's later compilation.^[15] Old Great Bulgaria's establishment marked the first recorded Bulgar polity independent of nomadic overlords, fostering a multi-ethnic steppe entity that balanced Bulgar dominance with subordinate tribes, setting the stage for subsequent migrations.^[18] Byzantine sources, while potentially biased toward imperial alliances, provide the primary textual evidence, corroborated by the Pereshchepina treasure hoard—discovered in 1912 and linked to Kubrat's burial—containing artifacts indicative of high-status nomadic leadership from the mid-7th century.^[15] This confederation's viability relied on Kubrat's diplomatic maneuvering, including nominal Christian influences from Heraclius, though pagan practices predominated among the warrior elite.^[6]

Administrative and Military Structure

Kubrat's Old Great Bulgaria functioned primarily as a tribal confederation, uniting the Onogur, Kutrigur, and Utigur Bulgar groups along with allied tribes in the Pontic-Caspian steppes following his consolidation of power around 632.^[16] The central authority rested with the ruler, who exercised supreme leadership over a decentralized system reliant on tribal loyalties and nomadic mobility rather than fixed bureaucratic institutions.^[4] Decision-making involved consultation with a council of great boyars (boyls), representing tribal elites, which helped maintain cohesion among the diverse confederated groups.^[9] High-ranking subordinates included the kavkhan, serving as the ruler's deputy and second-in-command in the administrative hierarchy, and the ichirguboyl (or lchirguboyl), a third key figure often associated with oversight of specific regions or functions.^[9] These officials typically combined civil governance with military command, reflecting the integrated nature of authority in steppe polities where administrative roles extended to mobilizing and leading warriors.^[20] This structure drew partial influence from Kubrat's exposure to Byzantine statecraft during his upbringing in Constantinople, though it remained adapted to Bulgar nomadic traditions without evidence of formalized taxation or permanent settlements.^[9] The military organization mirrored the confederative framework, drawing on tribal levies organized into contingents under boyar leaders and high officials like the kavkhan, who commanded large units in warfare.^[20] Forces emphasized mobility, with Bulgar warriors employing horse archery, lances, and composite bows typical of Eurasian steppe tactics, enabling effective defense against nomadic rivals such as the Khazars during Kubrat's reign (c. 632–665).^[4] Primary Byzantine accounts, including those of Theophanes the Confessor, attest to Kubrat's success in subduing neighboring tribes and forging alliances, implying a cohesive military capable of projecting power across the region north of the Black Sea, though exact troop numbers and formations remain unrecorded.^[21] This system sustained the state's independence until pressures mounted after Kubrat's death, when fragmented succession undermined unified command.^[6]

Economic Foundations

The economy of Old Great Bulgaria under Ruler Kubrat (r. c. 630–c. 642) rested primarily on nomadic pastoralism, leveraging the expansive grasslands of the Pontic-Caspian steppe for herding horses, sheep, and cattle. These activities supplied essential foodstuffs, wool, hides, and dairy products, while horses underpinned military mobility and served as prestige goods for exchange or tribute. The confederation's semi-nomadic structure, uniting Onogur Bulgars with Kutrigur and Utigur tribes, centralized resource management and enabled seasonal migrations between summer pastures near the Black Sea and winter quarters along rivers like the Don and Kuban.^[22] Unification under Kubrat facilitated the extraction of tribute from vassal groups and weaker neighbors, supplementing pastoral yields with inflows of livestock, slaves, and raw materials acquired through warfare or diplomacy. This system mirrored broader Eurasian steppe economies, where non-autarkic nomads relied on external procurement of grains, metals, and manufactures via raids, tribute, or barter to offset limitations in agriculture and craftsmanship. Control over steppe corridors positioned Old Great Bulgaria to intercept trade flows, potentially exchanging furs, hides, and mounts for Byzantine or Caucasian goods, though direct evidence of volume or routes remains limited.^[23] The Byzantine alliance, cemented by Emperor Heraclius (r. 610–641) granting Kubrat the patrician title around 619–620 following his education in Constantinople, likely introduced regulated exchanges, including diplomatic gifts of silk, weapons, and coinage for Bulgar horses vital to imperial cavalry. Such ties integrated the state into Mediterranean networks, providing access to luxury imports amid pressures from Avar and Khazar rivals. Archaeological traces, including horse burials and nomadic encampment artifacts from the lower Don region, corroborate a pastoral base with intermittent sedentary elements, but the polity's brevity and mobility constrain detailed quantification of output or surplus generation.^[24]

Foreign Relations and Conflicts

Alliance with Byzantium

Kubrat forged a close alliance with the Byzantine Empire, rooted in his formative years spent in Constantinople under Emperor Heraclius (r. 610–641). Educated at the imperial court and baptized into Orthodox Christianity around 619, Kubrat developed a personal friendship with Heraclius, which facilitated diplomatic ties upon his return to the Pontic steppes circa 619–632.^[25] This connection positioned him as a reliable partner against shared adversaries, including the Avar Khaganate, which had previously dominated Onogur-Bulgar groups.^[26] Following his unification of Bulgar tribes into Old Great Bulgaria around 632–635, Kubrat negotiated a formal treaty with Heraclius, likely between 635 and 636, securing Byzantine recognition and material support. Heraclius granted Kubrat the prestigious title of patricius, accompanied by lavish gifts, affirming the alliance's mutual benefits in countering nomadic incursions from the east and north.^[27] ^[26] This pact enabled Kubrat to consolidate power free from Avar overlordship while providing Byzantium a buffer against steppe threats during Heraclius's campaigns against the Sassanid Persians.^[28] The alliance endured beyond Heraclius's death in 641, as Kubrat backed the claims of the emperor's widow, Martina, and their son Heraclonas amid Byzantine succession intrigues, though this support did not alter the core strategic partnership focused on regional stability. Primary accounts, such as those in Theophanes the Confessor and Patriarch Nikephoros I, indirectly corroborate these ties through references to Kubrat's rule over the Onogundurs and his independence from khaganate control, consistent with Byzantine diplomatic influence.^[29] No direct evidence of military joint operations survives, but the arrangement's longevity underscores its pragmatic foundation in shared interests rather than ideological alignment.^[30]

Engagements with Khazars and Other Nomads

Kubrat's confederation of Old Great Bulgaria contended with the expansionist Khazar Khaganate, a semi-nomadic Turkic polity centered east of the Volga River that asserted dominance over steppe territories following the collapse of the Western Turkic Khaganate around 630. Positioned between the Dnieper and Kuban rivers, Kubrat's realm directly abutted Khazar spheres of influence, fostering territorial rivalries over pastoral lands and trade routes in the Pontic-Caspian region. Although surviving Byzantine chronicles do not enumerate pitched battles under Kubrat's direct command (c. 632–665), the delayed Khazar conquest until after his death underscores his success in repelling or deterring incursions through fortified settlements, tribal levies, and possibly auxiliary alliances.^[31] Patriarch Nikephoros I of Constantinople, in his Short History composed in the early 9th century, recounts that following Kubrat's demise during the reign of Emperor Constans II (641–668), the Khazars "came from the eastern parts" and compelled Kubrat's eldest son and successor, Batbayan, to submit as a vassal, thereby dismantling the eastern core of Great Bulgaria around 670. This account, corroborated in broader outlines by Theophanes the Confessor's Chronographia, highlights the Khazars' opportunistic strike amid succession fragmentation, implying Kubrat's prior engagements—likely border skirmishes or preemptive raids—had preserved autonomy via a robust military apparatus centered on heavy cavalry drawn from Bulgar and allied nomadic warriors. The Khazars' victory extracted tribute and fragmented the confederation, with Batbayan's forces numbering in the tens of thousands unable to withstand the assault.^[32] Interactions with other nomadic entities involved both consolidation and contention. Kubrat integrated fractious Bulgar subgroups such as the Kutrigurs (west of the Don) and Utigurs (east of the Don), nomadic pastoralists previously splintered by Avar incursions and internal rivalries, through a combination of coercive campaigns and oaths of fealty, forging a multi-tribal polity estimated at 10,000–20,000 warriors strong. These efforts neutralized intra-Bulgar nomadic threats, as evidenced by the enduring unity under his rule despite prior divisions dating to the 5th–6th centuries. Limited evidence suggests peripheral dealings with Caucasian nomads like the Alans, whose mountain-steppe domains bordered Kubrat's southern flanks, potentially involving raids or tribute exchanges to secure trade access to the Caucasus, though primary texts prioritize the Khazar dynamic.^[33]

Death, Succession, and Dissolution

Circumstances of Death

Kubrat died around 665 AD, during the reign of Byzantine Emperor Constans II (641–668 AD), as recorded in Byzantine historical accounts.^[25] The precise cause of death is not specified in surviving sources, with indications pointing to natural causes in advanced age rather than battle or assassination, given the absence of reports of violence and the context of his final admonitions to his heirs.^[10] Prior to his death, Kubrat summoned his five sons—Batbayan, Kotrag, Kuber, Alcek, and Asparuh—and urged them to maintain unity against external threats, illustrating the point by binding vine shoots together, which proved unbreakable, versus breaking them individually.^[25] This testament, preserved in the writings of Patriarch Nikephoros I of Constantinople (c. 758–828 AD), reflects Kubrat's awareness of impending vulnerabilities, including pressures from the Khazar Khaganate, though his death itself occurred before the full dissolution of Old Great Bulgaria.^[6] Earlier traditions placed his death in Phanagoria, the apparent capital near the Sea of Azov, but archaeological reassessments of burial evidence have cast doubt on this location.^[10] The Byzantine chronicler Theophanes the Confessor provides corroborating temporal details, aligning Kubrat's demise with Constans II's campaigns in the West (663–668 AD), underscoring the ruler's established diplomatic ties with Constantinople up to that point. No contemporary non-Byzantine sources detail the event, limiting insights to these accounts, which, while potentially shaped by imperial perspectives, remain the primary evidence for 7th-century Pontic steppe events.

Division Among Heirs

Following Kubrat's death around 665 AD, Old Great Bulgaria fragmented as his five sons—Batbayan, Kotrag, Kuber, Alcek, and Asparukh—led separate groups amid Khazar military pressure on the Pontic steppes.^[34] Patriarch Nikephoros I records that Kubrat, on his deathbed, urged unity among his heirs through the analogy of bundled rods that could not be broken individually, yet this counsel failed to prevent dispersal.^[6] The eldest, Batbayan, inherited the core territories near the Sea of Azov but submitted to Khazar overlordship, retaining nominal rule as a vassal while the khaganate absorbed the region's independence.^[34] Kotrag, the second son, migrated northeast with followers to the middle Volga River basin, establishing a durable Bulgar polity there that evolved into Volga Bulgaria and endured for centuries until the 13th-century Mongol conquests.^[34] Kuber directed his contingent westward into the Avar Khaganate's Pannonia around 670 AD, where they served as foederati before rebelling circa 680 AD and relocating to Byzantine-held Macedonia, as attested in later Balkan sources linking Kuber's group to regional upheavals.^[35] Asparukh, another son, advanced southwest across the Danube Delta, securing territory from Byzantine forces in 680–681 AD and founding the Danube Bulgar state, later the First Bulgarian Empire, through victories like the Battle of Ongal.^[6] Alcek's trajectory is the least documented; traditions preserved in secondary accounts suggest he led a smaller band westward, possibly toward Italy or the Adriatic, but primary Byzantine chronicles provide no firm confirmation, indicating his group likely disintegrated or assimilated en route.^[35] This partition, driven by nomadic power vacuums and Khazar expansion, dissolved Kubrat's confederation into disparate migrations, seeding multiple Bulgar successor entities across Eurasia.^[15]

Fall to Khazar Pressure

Following Kubrat's death around 665 AD, the Khazar Khaganate, undergoing territorial expansion eastward from the Caspian region, exerted mounting military pressure on the weakened confederation of Old Great Bulgaria.^[4] The Khazars, having previously consolidated power over neighboring Onogur territories, launched incursions that targeted the Pontic steppe heartlands, exploiting internal divisions among Kubrat's successors.^[17] Kubrat's eldest son, Batbayan, inherited the central territories but proved unable to repel the Khazar assaults, submitting to their overlordship by approximately 668 AD after a brief rule of about three years.^[36] This subjugation marked the effective collapse of unified authority in Old Great Bulgaria, as Khazar forces imposed tribute and disrupted the Bulgar tribal alliances.^[37] The remaining heirs, including Kotrag, Asparukh, and Kuber, defied Kubrat's reported deathbed counsel to maintain cohesion against external threats, instead dispersing with portions of their followers to evade total Khazar domination.^[4] Kotrag migrated northward to the Volga River basin, establishing a Bulgar polity there under nominal Khazar suzerainty; Asparukh led groups westward across the Danube, founding the Danube Bulgar state; while others, such as Kuber, sought refuge in the Balkans or Pannonia.^[17] These migrations, driven by relentless Khazar campaigns, fragmented Old Great Bulgaria into diaspora entities by the late 7th century, ending its existence as a coherent steppe power.^[36]

Evidence and Sources

Primary Historical Accounts

The primary historical accounts of Kubrat originate from Byzantine chroniclers of the 8th and 9th centuries, who provide the most detailed narratives despite composing their works decades after his death around 665 AD. These sources portray Kubrat as a ruler of the Onogundurs (or Unogundur-Bulgars), a Bulgar confederation in the Pontic-Caspian steppe, emphasizing his independence from Avar overlordship and his alliance with Emperor Heraclius (r. 610–641). Theophanes the Confessor's Chronographia, completed circa 810–814, describes Kubrat as having been raised and baptized in Constantinople, where he formed a close friendship with Heraclius, before returning to subjugate neighboring tribes—including Kutrigurs, Utigurs, and others—establishing a unified polity known as Old Great Bulgaria extending from the Sea of Azov to the Kuban River.^[38]^[39] The chronicle notes his receipt of the imperial title patrikios and military support against Persian and Avar threats, framing his state as a Byzantine-aligned buffer.^[15] Patriarch Nikephoros of Constantinople's Short History (covering 602–769), written circa 780–797, corroborates Theophanes by identifying Kubrat explicitly as "lord of the Onogundur" and ruler over a Bulgar-Onogur union around Lake Maeotis (Sea of Azov). Nikephoros recounts Kubrat's revolt against the Avars circa 634–635, his consolidation of power over disparate nomad groups, and the subsequent division among his five named sons—Batbayan, Kotrag, Asparukh, Kuber, and Alcek—following his death, which led to the polity's fragmentation under Khazar expansion.^[38]^[40] Both chroniclers attribute to Kubrat a deathbed exhortation to his heirs to maintain unity against external pressures, a detail underscoring themes of imperial loyalty and the perils of disunity in steppe politics; however, Batbayan's portion in the core territories fell to the Khazars, while Asparukh migrated westward to the Danube.^[6] An independent Egyptian account appears in John of Nikiu's Chronicle (late 7th century, preserved in Ethiopic translation), which depicts Kubrat as a "prince of the Huns" baptized in childhood, educated at the Byzantine court, and a trusted ally of Heraclius in campaigns against common foes. This source, drawing from near-contemporary Coptic traditions, aligns with Byzantine emphasis on Kubrat's Christianization but omits details of his steppe empire, focusing instead on his role in imperial diplomacy circa 619–628.^[38] Later Syriac chronicles, such as Michael the Syrian's (12th century, synthesizing earlier materials), echo the five-sons motif and migration narratives, likely deriving from shared Byzantine antecedents rather than unique testimony.^[41] These accounts, while valuable for synchronizing Kubrat's floruit with Heraclius' reign (e.g., events dated to AM 6143 or 630–665 in Theophanes' annalistic framework), reflect Byzantine historiographical priorities—such as promoting Christian rulers and alliances—potentially telescoping events and understating internal Bulgar dynamics. No Bulgar autogenous records survive, rendering these external Greco-Roman and Coptic sources the foundational, albeit filtered, testimonies.^[39]

Archaeological Findings

The Pereshchepina hoard, unearthed in 1912 near the village of Mala Pereshchepyna in Poltava Oblast, Ukraine, represents the primary archaeological assemblage linked to Kubrat's era. Discovered by local shepherds in a kurgan burial mound, it consists of approximately 800 artifacts, predominantly gold (totaling about 25 kilograms) and silver items (about 15 kilograms), including 19 silver vessels, 16 gold buckles and fittings, ceremonial weaponry such as swords and daggers, horse harnesses, jewelry, and Byzantine-style amphorae.^[42] ^[43] The artifacts date to the mid-7th century, aligning with Kubrat's reign (circa 632–665), and reflect a synthesis of steppe nomadic traditions with Byzantine influences, evidenced by Greek inscriptions on some vessels and the high craftsmanship of the goldwork.^[44] Scholars, including German archaeologist Joachim Werner in his 1984 analysis, have attributed the hoard to Kubrat's tomb based on its exceptional wealth—indicative of a supreme ruler's interment—the geographical location within the core territory of Old Great Bulgaria along the Vorskla River, and specific items like a sword and ring interpreted as diplomatic gifts from Byzantine Emperor Heraclius, Kubrat's ally against the Avars and Persians.^[43] The burial's structure, a wooden chamber within the mound containing the deceased's skeleton alongside the treasures, underscores elite Proto-Bulgar funerary practices, with no evidence of horse sacrifice but emphasis on portable wealth for the afterlife.^[44] While the identification remains inferential rather than proven by direct epigraphy naming Kubrat, the hoard's scale surpasses other contemporaneous steppe finds, supporting its association with the ruler's status.^[42] Additional evidence from Kubrat's realm derives from excavations in the Pontic-Caspian steppes, where kurgans and settlements reveal 7th-century Proto-Bulgar material culture, including iron weapons, pottery with incised designs, and fortified sites blending nomadic and sedentary elements. Phanagoria, on the Taman Peninsula and identified as Kubrat's capital in historical accounts, has yielded medieval layers from ongoing digs since the 19th century, including Byzantine coins and amphorae fragments datable to the 630s–660s, suggesting administrative continuity under Bulgar rule amid the Greek city's decline.^[45] However, these findings lack direct ties to Kubrat personally, serving instead to contextualize Old Great Bulgaria's urban-nomadic hybrid economy and alliances.^[46] Surface surveys and limited mound explorations in the Don and Kuban regions have uncovered analogous grave goods, such as belt buckles and arrowheads, corroborating the hoard's stylistic attributions to Kutrigur and Onogur Bulgar groups under Kubrat's confederation.^[47]

Legacy and Interpretations

Influence on Bulgar Diasporas

Following Kubrat's death after 651 AD, the dissolution of Old Great Bulgaria under Khazar pressure prompted his five sons to lead separate migrations, establishing Bulgar-led polities that constituted the primary diasporas.^[4] These movements, documented in Byzantine chronicles such as those of Theophanes the Confessor and Nikephoros I, preserved Kubrat's legacy of tribal unification and royal lineage (Dulo clan) across dispersed territories.^[6] The eldest son, Batbayan, succeeded Kubrat but faced Khazar invasion around 668 AD, resulting in subjugation and the core territory's absorption into the Khazar Khaganate; remnants under his rule maintained nominal Bulgar identity briefly before assimilation.^[4] Kotrag, the second son, migrated northeast to the Middle Volga region, founding Volga Bulgaria near the confluence of the Volga and Kama rivers circa 670 AD; this state endured independently until its conquest by the Mongols in the 13th century, adopting Islam in 922 AD and influencing subsequent Volga Tatar culture through retained Bulgar administrative and linguistic elements.^[4]^[6] Asparukh, the third son, directed approximately 50,000 Bulgars westward across the Danube around 679–680 AD, defeating Byzantine Emperor Constantine IV at the Ongal marsh in 681 AD and establishing the Danube Bulgar Khanate (precursor to the First Bulgarian Empire), which expanded under his successors and formed the basis of modern Bulgaria's ethnogenesis.^[4] Kuber, another son, led a group to Pannonia before relocating to the Balkans (Macedonia region) circa 680 AD, where his followers integrated with local Slavs and briefly challenged Byzantine authority under Justinian II.^[4] The fifth son, Altsek, migrated to southern Italy, where a small Bulgar community persisted into the early medieval period, evidenced by toponyms and artifacts.^[6] Kubrat's influence on these diasporas stemmed from his creation of a centralized confederation that instilled a shared Bulgar identity, enabling his heirs to legitimize new states through claimed descent and adoption of similar khagan titles; however, over time, Danube Bulgars underwent significant Slavicization, while Volga Bulgars Turkicized further under Islamic and Kipchak influences, diluting direct ethnic continuity.^[4] Archaeological finds, such as the Pereshchepina treasure (discovered 1912, associated with Kubrat's burial), underscore the material culture transmitted to these groups, including runic inscriptions and nomadic regalia.^[6]

Debates on Ethnicity and Origins

The ethnic composition of Kubrat's confederation in Old Great Bulgaria (c. 632–665) has sparked ongoing scholarly debate, centered on whether the Proto-Bulgarians represented a primarily Turkic nomadic elite, an Iranian (Scythian-Sarmatian) group, or a mixed ethnogenesis incorporating diverse steppe populations. Primary evidence from linguistics and archaeology points to a Turkic-speaking ruling class under Kubrat, who belonged to the Dulo clan, with historical accounts linking them to Oghuric Turkic tribes such as the Onogurs and Kutrigurs active in the Pontic-Caspian region.^[48] This view is bolstered by Bulgar titles like khan and the use of a 12-year animal calendar, hallmarks of Turkic khaganates from Central Asia.^[49] Linguistic remnants further substantiate the Turkic affiliation of the Proto-Bulgarian elite: the language belonged to the Oghuric branch of Turkic, distinct from Common Turkic but related to modern Chuvash, with attested words, phrases, and inscriptions (e.g., in the Namelist of rulers) showing Turkic morphology and lexicon limited to military-administrative contexts.^[49] Kubrat's name itself derives plausibly from Turkic roots such as qobrat ("to gather" or connoting assembly/strength) or qurt ("wolf"), aligning with nomadic titulature.^[48] Byzantine chroniclers like Theophanes, who record Kubrat's alliances and realm, portray his people as steppe warriors akin to other Turkic confederations post-Hunnic dissolution, without Iranian linguistic indicators.^[48] Counterarguments favoring Iranian origins emphasize anthropological data: Proto-Bulgarian burials exhibit Europeoid cranial features with artificial skull deformation akin to Sarmatian practices, and minimal Mongoloid admixture, challenging a pure Central Asian Turkic migration.^[48] Proponents cite onomastic parallels (e.g., some clan names) and cultural continuity with earlier Iranian nomads in the North Pontic zone, suggesting Kubrat's group evolved from Alano-Sarmatian remnants Turkicized superficially. However, this hypothesis falters against the Turkic linguistic corpus—only about 40 words preserved, but unequivocally Oghuric—and lacks primary texts supporting Iranian as the core language during Kubrat's era.^[49]^[48] A synthesis advanced by archaeologists like Rasho Rashev posits a hybrid model: a Turkic military elite (evident in Kubrat's Phanagoria-based state near the Azov Sea) ruling over a substrate of Iranian (Sarmatian-Alan), Ugro-Finnic, and emerging Slavic elements from Eastern Europe, with assimilation blurring ethnic lines by the time of dissolution.^[48] Archaeological surveys of Great Bulgaria sites yield mixed artifacts—Pastirki pottery linking to Danube traditions, but elite goods echoing Turkic steppe norms—indicating confederative rather than monolithic ethnicity. This aligns with genetic studies showing low Turkic autosomal input in later Balkan Bulgarians, attributable to elite replacement and Slavic demographic dominance post-migration, rather than negating the founding stratum's Turkic character.^[48] Nationalist interpretations in some Bulgarian academia downplay Turkic roots to stress Thracian-Slavic continuity, but these prioritize ideological continuity over linguistic and historical empirics, which affirm the Proto-Bulgarians' steppe-Turkic agency under leaders like Kubrat.^[48]

In Bulgaria, the town of Kubrat in the Razgrad Province bears the ruler's name and hosts annual commemorations on May 24, including fairs and historical reenactments celebrating his legacy as the founder of Old Great Bulgaria.^[50] These events emphasize continuity between Kubrat's 7th-century confederation and modern Bulgarian statehood, drawing on primary accounts like those in Theophanes the Confessor.^[51] A bronze monument to Kubrat, erected in 2008 near Malaya Pereshchepina in Poltava Oblast, Ukraine—the site associated with his burial treasure—depicts him on horseback and commemorates Old Great Bulgaria's territory in the Pontic steppes.^[37] The structure was toppled by vandals on or before April 5, 2021, through undermining its foundations, prompting Bulgarian media reports attributing it initially to Ukrainian nationalists, though subsequent statements from Ukrainian groups condemned the act and called for restoration.^[52]^[53] Artifacts linked to Kubrat, such as a gold-inlaid sword and signet ring from the 1912 Pereshchepina treasure (containing over 850 items weighing 22 kg of gold), are exhibited in institutions like the National History Museum in Sofia, reinforcing his historical prominence; the sword, inscribed in Greek as a gift from Emperor Heraclius, symbolizes Byzantine-Bulgar alliances.^[43] Bulgarian nationalist narratives position Kubrat as the originator of Bulgarian ethnogenesis and the first sovereign ruler, asserting Old Great Bulgaria (c. 632–668) as the primordial state from which Danubian Bulgaria (founded 681) derived, often to underscore Turkic-Bulgar roots over later Slavic admixtures amid debates on genetic continuity evidenced by ancient DNA studies.^[51]^[16] Such claims, prominent in cultural heritage discourse, extend to irredentist undertones regarding Pontic territories now in Ukraine and Russia, where Kubrat's realm once spanned from the Dniester to the Kuban rivers, though archaeological evidence confirms its ephemeral nature before Khazar conquest.^[37] These interpretations prioritize Bulgar agency in state formation while downplaying the confederation's multi-ethnic composition of Onogur-Bulgars, Kutrigurs, and Utigurs, as described in Byzantine sources.^[16]
