East Europe (820 – 963 CE): Varangian Routes, Khazar Gateways, and the Making of Rus’

Geographic and Environmental Context

East Europe includes Belarus, Ukraine, the European portion of Russia, and the sixteen Russian republics west of the Urals.

• A vast transition from northern taiga and mixed forests to southern forest-steppe and Pontic steppe, threaded by great rivers—the Dnieper, Volga, Dvina, Oka, and Don.

• Major nodes formed along portage chains between the Baltic, Caspian, and Black Sea basins, especially at Novgorod, Smolensk, Kiev, and Volga Bulgar markets.

Climate and Environmental Shifts

• A cool–temperate regime prevailed; by the mid-10th century the onset of the Medieval Warm Period (c. 950–1250) modestly lengthened growing seasons in the forest-steppe.

• Flood pulses on the Dnieper and Volga structured seasonal travel; winter freeze created over-ice corridors for sled transport.

Societies and Political Developments

• Varangians and Tribal Unions (9th c.): Scandinavian merchant-warriors (Varangians) entered forest trade routes, installing ruling groups among Slavic and Finnic unions—Krivichs, Drevlians, Severians, Radimichs, Vyatichs, and others.

• Rurik and Oleg: Tradition places Rurik at Novgorod (862); his kinsman Oleg seized Kiev (882), uniting the “route from the Varangians to the Greeks.” Kiev became the core of   Kievan Rus’, extracting tribute from neighboring tribes and mediating steppe diplomacy.

• Khazar Khaganate: The Khazars controlled the lower Volga–Don and Caspian Gate, taxing trade between the steppe and Islamic markets; their elite adopted Judaism (9th c.). Rus’ princes alternately paid tribute, raided Khazar towns, and competed for Volga access.

• Volga Bulgars: A commercial polity at the Volga–Kama confluence; conversion to Islam (922) under Almış tied them to the Samanid economy.

• Steppe Frontiers: After c. 895 the Magyars moved into the Carpathian Basin; Pechenegs replaced them on the Pontic steppe, pressuring Rus’ river traffic and Sarmatian corridors.

• Byzantine Relations: Rus’ raids on Constantinople (notably 860) gave way to treaties (907/911 per later compilations), regulating trade duties and mercenary service.

Economy and Trade

• Exports: high-value furs, wax, honey, slaves, and falcons moved south on river craft; iron swords and worked amber moved internally along forest routes.

• Imports: Byzantine silk, wine, fine metalwork via the Dnieper; Samanid silver dirhams, glassware, and textiles via the Volga.

• Monetization: massive inflows of Samanid dirhams fueled a hack-silver economy; coin hoards appear from Ladoga/Novgorod to the middle Dnieper and upper Volga.

• Kiev and Novgorod functioned as hinge markets, auditing tolls and tribute before goods crossed portages toward Cherson and Constantinople, or toward Volga Bulgar and the Caspian.

Subsistence and Technology

• Agriculture: forest-steppe communities practiced plow agriculture (millet, rye, wheat) with slash-and-burn in the forest zone; stock-keeping expanded in river meadows.

• Crafts: iron tools, plows, and broad-seax blades; antler combs, bone skates, glass beads; early urban smithies in Ladoga, Novgorod, Kiev.

• River boats: light dugouts and plank-built craft—monoxyla—ported between watersheds; winter travel used sleds over frozen rivers.

• Fortifications: earthen ramparts and timber palisades ringed hillforts (gorodishche); princes maintained druzhina (retinues) of armored cavalry and river fighters.

Movement and Interaction Corridors

• “From the Varangians to the Greeks”: the Dvina–Dnieper and Volkhov–Dnieper chains funneled Baltic goods to the Black Sea; the Dnieper porohy (rapids) demanded portage and escorts through Pecheneg country.

• Volga Route: Ladoga/Novgorod → Volga → Volga Bulgar → Khazaria → Caspian, connecting to Samanid markets in Gurgān and Tabaristan.

• Forest Portages: Smolensk, Rzhev, and Gorodets nodalized crossings between upper river systems, creating dense hub-and-spoke exchanges.

Belief and Symbolism

• Slavic paganism (Perun, Veles), Finnic and Baltic animisms, and Norse cults coexisted among Varangian elites and local communities; shrines and sacred groves sacralized hilltops and river bends.

• Khazars patronized Judaism at court; Volga Bulgars normalized Islamic law and markets after 922.

• Christianity: Byzantine missions influenced Crimea and lower Dnieper; individual baptisms occurred among elites, but mass conversion of Rus’ came later (988).

Adaptation and Resilience

• Dual-route strategy (Dnieper + Volga) hedged against steppe raids and political tolls; when Pechenegs blocked the Dnieper, merchants shifted to the Volga.

• Seasonal logistics—summer navigation, winter sled freight—smoothed transport risk; caches and fortified gorodishche protected goods and people.

• Tribute diplomacy balanced payments to Khazars and Pechenegs with punitive raids and alliances, keeping corridors open.

• Urban niches (Ladoga, Novgorod, Kiev) developed storage, craft specialization, and legal customs for foreign merchants, stabilizing long-distance exchange.

Long-Term Significance

By 963 CE, East Europe had coalesced into a river-route commonwealth under emerging Kievan Rus’, framed by Khazar gatekeeping on the Caspian and Byzantine markets on the Black Sea.

• Silver-driven commerce integrated forest, steppe, and sea;

• Tribal unions and Varangian retinues forged the institutions of Rus’ rulership;

• Volga Bulgar Islam and Khazar Judaism embedded the region in wider religious economies.

On the eve of the next age, Sviatoslav’s campaigns (from 964) would crack Khazar hegemony, Pecheneg pressure would intensify, and the Dnieper metropolis of Kiev would begin its ascent toward high-medieval preeminence.

Igor of Kiev is killed while collecting tribute from the Drevlyans in 945.

The Byzantine historian and chronicler, Leo the Deacon (born around 950), describes how Igor met his death: "They had bent down two birch trees to the prince’s feet and tied them to his legs; then they let the trees straighten again, thus tearing the prince’s body apart.")

He is avenged by his wife, Olga of Kiev.

The Primary Chronicle blames his death on his own excessive greed, indicating that he was attempting to collect tribute a second time in a month.

As a result, Olga changes the system of tribute gathering (poliudie) in what may be regarded as the first legal reform recorded in Eastern Europe.

Constantine Zuckerman, drastically revising the chronology of the Primary Chronicle, argues that Igor actually reigned for three years, between summer 941 and his death in early 945.

He explains the epic thirty-three-year span of his reign in the chronicle by its author's faulty interpretation of Byzantine sources.

Indeed, none of Igor's activity are recorded in the chronicle prior to 941.

Sviatoslav, a member of the Varangian Rurik dynasty, succeeds his father as duke of Kiev; his mother, Olga, rules as regent.

Virtually nothing is known about Sviatoslav's childhood and youth, which he spent reigning in Novgorod.

Sviatoslav was tutored by a Varangian named Asmud (meaning "quick as a leopard").

The tradition of employing Varangian tutors for the sons of ruling princes will survive well into the eleventh century.

Princess Olga, the widow of Igor I, Grand Prince of Kiev, who had been assassinated in 945 by his subjects while attempting to extort excessive tribute, had become regent (for their son, Sviatoslav) of the grand principality of Kiev.

She had soon had Igor's murderers scalded to death and hundreds of their followers killed.

Olga is the first Rus' ruler to convert to Christianity, either in 945 or in 957.

The ceremonies of her formal reception in Constantinople are minutely described by Emperor Constantine VII in his book De Ceremoniis.

Following her baptism, she takes the Christian name Yelena, after the reigning Empress Helena Lekapena.

The Slavonic chronicles add apocryphal details to the account of her baptism, such as the story how she charmed and "outwitted" Constantine and how she spurned his matrimonial proposals.

In truth, at the time of her baptism, Olga was an old woman, while Constantine had a wife.

East Europe (964 – 1107 CE): Kievan Rus’ Ascendancy, Khazar Eclipse, and Christianization of the Dnieper

Geographic and Environmental Context

East Europe includes Belarus, Ukraine, the European portion of Russia, and the sixteen Russian republics west of the Urals.

• Vast forest, forest-steppe, and steppe zones were organized by the great rivers: the Dnieper, Volga, Dvina, Don, and Oka.

• Northern Novgorod–Ladoga controlled access to Baltic and Volga routes; southern Kiev commanded the Dnieper trade to the Black Sea and Byzantium.

• Steppe frontiers were dominated by Pechenegs and later Cumans/Polovtsians, shaping politics and warfare.

Climate and Environmental Shifts

• The Medieval Warm Period (c. 950–1250 CE) improved growing seasons in the forest-steppe, allowing agricultural expansion into river valleys and uplands.

• Longer ice-free navigation windows extended the transport season on the Dnieper and Volga.

• Yet steppe droughts could provoke nomadic incursions, intensifying frontier vulnerability.

Societies and Political Developments

• Khazar Collapse:

  • Prince Sviatoslav of Kiev (r. 945–972) launched campaigns (964–969) that destroyed Khazaria’s capital Itil, ending its centuries-long dominance of the Volga–Caspian gateway.

  • This shifted hegemony over the Volga trade to Volga Bulgars and emerging Rus’ markets.

• Kievan Rus’:

  • Oleg had earlier forged Kiev as a Varangian–Slavic hub; after 964, Sviatoslav expanded east (Volga Bulgars), south (Khazars), and west (Balkans).

  • His successors consolidated Kiev as the metropolis of a riverine commonwealth.

  • Vladimir I (r. 980–1015) secured Dnieper routes, fought Poles and steppe tribes, and in 988 converted to Christianity, baptizing Kiev and aligning Rus’ with Byzantine Orthodoxy.

  • Yaroslav the Wise (r. 1019–1054) codified law (Russkaya Pravda), patronized cathedrals (St. Sophia in Kiev), and arranged dynastic marriages with Europe.

  • After 1054, Rus’ fragmented into princely appanages, though Kiev remained primate; Novgorod, Chernigov, Pereyaslavl, and Smolensk rose as regional centers.

• Volga Bulgars: Islamized in 922, they prospered after Khazar decline, controlling Volga–Kama trade and mediating furs/slaves to Islamic markets.

• Steppe Nomads:

  • Pechenegs dominated the Pontic steppe through the 10th–11th c., repeatedly besieging Kiev (notably 968, 1017, 1036).

  • By mid-11th c., the Cumans (Polovtsians) displaced them, pressuring Rus’ frontiers and raiding Dnieper settlements.

Economy and Trade

• Exports: furs, wax, honey, and slaves from Slavic and Finnic forests; falcons and horses from the steppe.

• Imports: Byzantine silks, wine, and liturgical objects via the Dnieper; Islamic silver, glassware, and textiles via the Volga.

• Monetization: Samanid dirham flows declined after c. 970; hack-silver economies persisted, supplemented by Byzantine coins and local bullion.

• Urban markets: Kiev became a transshipment emporium, Novgorod a northern hub linked to Baltic traders, and Smolensk a portage node.

• Agricultural surpluses grew with expansion into fertile steppe borderlands.

Subsistence and Technology

• Agriculture: plow farming spread in fertile chernozem belts; rye, wheat, barley, and millet expanded.

• Stock raising: horses, cattle, and sheep herds flourished in forest-steppe zones.

• Crafts: smithies produced axes, swords, and armor; workshops turned out jewelry, glass beads, and church art.

• Architecture: from timber fortresses to stone cathedrals (Byzantine models) in Kiev, Novgorod, and Chernigov.

• Transport: Dnieper monoxyla and larger plank boats; winter sledges remained essential for bulk goods.

Movement and Interaction Corridors

• Dnieper route: Kiev monopolized tolls and tribute along the “road to the Greeks,” funneling merchants to Black Sea markets.

• Volga route: Volga Bulgars mediated trade north to the Kama and south to the Caspian.

• Forest portages: Novgorod secured crossings linking Baltic and Dnieper–Volga basins.

• Steppe corridors: nomadic pressure forced princes to build alliances or pay tribute to Pechenegs and Cumans to safeguard caravans and rafts.

Belief and Symbolism

• Slavic paganism: persisted until Vladimir’s baptism (988), with Perun (thunder god) as Kiev’s patron.

• Christianization: post-988, Byzantine Orthodoxy spread rapidly; churches, monasteries, and literacy (Cyrillic) transformed elite culture.

• Volga Bulgars: Islamic law and mosques anchored their trading state.

• Cumans and Pechenegs: maintained sky-god (Tengri) cults and steppe shamanism, influencing Rus’ through diplomacy, warfare, and intermarriage.

Adaptation and Resilience

• Political duality: dynastic marriages and church alliances tied Kiev to Europe and Byzantium, while tribute diplomacy managed steppe threats.

• Economic redundancy: dual reliance on Dnieper–Byzantine and Volga–Islamic routes hedged against political instability.

• Urban resilience: Kiev, Novgorod, and Smolensk diversified crafts and garrisons, absorbing shocks from raids and succession crises.

• Cultural adaptation: integration of Byzantine law and ritual stabilized rule while retaining Slavic customary law (Russkaya Pravda).

Long-Term Significance

By 1107 CE, East Europe had become a Christian, urbanizing riverine commonwealth:

• Kiev stood as a metropolitan capital, though its power was shared with rising regional principalities.

• Orthodoxy redefined Rus’ identity, aligning it with Byzantium rather than Latin Europe or the Islamic world.

• Steppe powers shifted from Pechenegs to Cumans, intensifying frontier challenges.

• Volga Bulgars thrived as Islamic intermediaries in fur and silver trades.

This age laid the foundations for the “Rus’ principalities” system, whose fragmentation and frontier exposure would shape its fate in the age of Mongol conquest two centuries later.

Southeast Europe (964 – 1107 CE): Byzantine Resurgence, Bulgarian Integration, and Adriatic–Danubian Corridors

Geographic and Environmental Context

Southeast Europe in this age stretched from Thrace and the Lower Danube through Macedonia and the Morava–Vardar axis to the Adriatic littoral and Dalmatian islands, encompassing nearly all Bulgaria (except the southwest), Romania and Moldova, northeastern Serbia, northeastern Croatia, extreme northeastern Bosnia, and Greece outside Thrace (Attica, Boeotia, Peloponnese, Epirus).
Core lowlands—Wallachian Plain, Lower Danube, Dobruja, Thracian basins—fed populous centers; Balkan passes (Shipka, Varbitsa), the Carpathian Gates, and the Via Militaris tied Belgrade–Niš–Sofia–Adrianople–Constantinople. To the west, the Via Egnatia linked Dyrrhachium (Durrës) with Thessaloniki, while Adriatic island ports (Zadar, Split, Trogir, Kotor, Ragusa) connected to Italy and the Aegean. Black Sea harbors (Varna, Constanţa) and Danube crossings remained strategic for trade and war.

Climate and Environmental Shifts

The Medieval Warm Period (c. 950–1250) lengthened growing seasons in Thrace and the Danube plain, boosting wheat, barley, and vine production. Flood pulses on the Danube and Maritsa set transport calendars. On the steppe margin, drought swings intensified pressures from Pecheneg and later Cuman nomads, shaping frontier policy and campaigning rhythms.

Societies and Political Developments

Bulgarian Decline and Absorption (10th–early 11th c.)
After Peter I (r. 927–969), Bulgaria faced internal strain and external shocks. Sviatoslav of Rus’ (968–971) seized Preslav, prompting John I Tzimiskes to intervene, defeat Sviatoslav, and annex eastern Bulgaria (971). Resistance shifted west under the Cometopuli; Samuel (r. 997–1014) forged a powerful Ohrid-centered empire. Basil II “Bulgar-Slayer” (r. 976–1025) dismantled it via relentless campaigns (notably Kleidion, 1014); by 1018, Bulgaria was fully integrated into the Byzantine system.

Byzantine Resurgence and Administration
The Macedonian dynasty consolidated the Balkans after 1018, reorganizing conquered lands into themes and reestablishing imperial garrisons and bishoprics from Thrace to the Danube marches. In Greece (outside Thrace)—Attica, Boeotia, the Peloponnese, and Epirus—imperial fiscal and judicial structures stabilized agrarian estates and port cities; rising aristocracies (proto-Komnenian milieu) gained regional weight.

Steppe Pressures and Frontier Politics
The Pechenegs dominated the Lower Danube steppe through the late 10th–11th centuries, raiding imperial and former Bulgarian lands; the empire alternated tribute, alliances, and force—culminating in decisive defeat of the Pechenegs with Cuman support (e.g., Levounion, 1091). Thereafter the Cumans (Polovtsians) became the chief nomadic threat along the Danube and into Wallachia and Moldova.

Western Alignments: Croatia, Serbia, Dalmatia
Croatia preserved kingship but, after dynastic ebb, entered a personal union with Hungary (1102), while its coastal communes bargained with Venice. Serbian principalities (Raška, Zeta) oscillated between imperial suzerainty and local assertion; Vukan’s line advanced late in the period. Dalmatian communes—Zadar, Split, Trogir, Kotor, Ragusa—codified statutes, expanded harbors, and played Byzantium, Hungary, and Venice against one another to preserve autonomy and commerce. Inland, Transylvania developed under Hungarian expansion after 1000, shaping northern Danubian balances.

Economy and Trade

Agrarian Core and Fiscal Integration
In Thrace and the Danube valley, grain, vines, and stock-raising thrived. After 1018, Byzantine praktika registered Bulgar peasantry into imperial tax law, channeling surplus to Adrianople, Thessaloniki, and Constantinople.

Corridors and Markets

• Danube artery: moved wax, honey, furs, grain, slaves between Rus’/Hungary and Constantinople.

• Via Militaris: imperial armies and caravans supplied inland garrisons and markets.

• Via Egnatia: fed Dyrrhachium and Thessaloniki, bridging Adriatic and Aegean.

• Black Sea ports: Varna, Constanţa connected Balkan produce to Byzantine and Rus’ circuits.

• Adriatic: Venetian convoys knit Dalmatia to Apulia and Ancona, re-exporting Balkan metals (Bosnian/Serbian silver, iron) and salt (e.g., Pag).
  Coinage: Byzantine nomismata and copper issues circulated widely; communal credit and notarial practices matured on the Adriatic.

Subsistence and Technology

Fortification & Arms
Byzantium rebuilt Preslav, fortified Sofia, Skopje, Adrianople, and strengthened Danube palisades. Imperial forces relied on cataphract cavalry and thematic infantry; Bulgarian levies served within imperial formations. Pecheneg/Cuman warfare emphasized horse archery and deep raids.
Rural/Maritime Infrastructures
Stone citadels multiplied in coastal and upland nodes; shipyards produced galleys and cogs for Adriatic convoys; inland estates improved presses, mills, and viticultural terraces.

Movement and Interaction Corridors

• Danube crossings—Ruse, Silistra, Vidin—were pivotal gates for steppe incursions and imperial counter-marches.

• Carpathian passes opened Magyar/Hungarian access into Transylvania and the lower Danube.

• Morava–Vardar and Drina–Sava channels linked inland Balkans to Aegean and Central Europe.

• Adriatic sea-lanes connected Dalmatia to Venice and Italian markets; Black Sea shipping tied ports to Rus’ and the capital.

Belief and Symbolism

Orthodoxy and Slavic Literacy
Orthodox Christianity, consolidated in Bulgaria under Boris and Simeon, was integrated into the Byzantine patriarchal orbit after 1018. Basil II confirmed the Ohrid Archbishopric’s autonomy, preserving Slavic liturgy and Cyrillic script; scriptoria at Ohrid and Preslav continued hagiography and law-text production.
Bogomilism
A dualist critique of hierarchy spread in 10th–11th centuries, embedding dissent within Balkan society and later influencing heretical currents westward.
Relic Cults and Icons
In Greek and Macedonian lands, icons, relics, and monastic networks reinforced imperial legitimacy and localized sanctity; along the Adriatic, Latin rites coexisted with Orthodox practice, especially in the communes.

Adaptation and Resilience

• Administrative absorption: Byzantine themes stabilized taxation, justice, and military service in newly integrated Bulgaria.

• Nomad diplomacy: tribute, alliance, and selective recruitment of Pecheneg/Cuman auxiliaries turned steppe pressures into tools of imperial statecraft.

• Communal governance: Dalmatian statutes and consulates lowered merchant risk and secured harbor revenues despite great-power rivalries.

• Cultural continuity: the Ohrid settlement safeguarded Slavic ecclesiastical autonomy and literacy under imperial rule.

Long-Term Significance

By 1107 CE, Southeast Europe had been reshaped into a Byzantine-led but polycentric landscape:

• Bulgaria—politically integrated into the empire—retained Slavic identity and ecclesiastical autonomy at Ohrid, ensuring cultural survival.

• Byzantium held Thrace and the Danube frontier, yet constant steppe raids taxed imperial resources even amid the Komnenian recovery.

• Pecheneg collapse and Cuman ascendancy redefined the northern threat; Hungary advanced in Transylvania, shifting power north of the Danube.

• Croatia–Hungary alignment (1102), Serbian consolidation, and Dalmatian communal strength set the stage for 12th-century realignments—Venetian maritime assertion, Komnenian strategies, and the eventual rise of the Second Bulgarian Empire.

This age fixed the region’s Orthodox Christian character, embedded Cyrillic literacy, and hardened the Byzantine–steppe frontier while keeping the Adriatic–Danubian–Aegean corridors open—foundations that would structure Balkan politics and commerce for the next century.

Eastern Southeast Europe (964 – 1107 CE): Bulgarian Decline, Byzantine Resurgence, and Steppe Pressures

Geographic and Environmental Context

Eastern Southeast Europe includes Turkey-in-Europe (Thrace), northeastern Greece (Thrace-in-Greece), nearly all of Bulgaria (except its southwestern portion), modern-day Romania and Moldova, northeastern Serbia, northeastern Croatia, and extreme northeastern Bosnia and Herzegovina.

• Core lowlands: the Lower Danube, Wallachian Plain, and Dobruja coast.

• Mountain corridors: Balkan passes (Shipka, Varbitsa), the Carpathian Gates into Transylvania, and the Via Militaris linking Belgrade–Niš–Sofia–Adrianople–Constantinople.

• The Black Sea ports (Varna, Constanţa) and Danube crossings remained vital for trade and war.

Climate and Environmental Shifts

• The Medieval Warm Period (c. 950–1250) brought longer growing seasons and greater agricultural surpluses in the Danube plain and Thrace.

• Stable monsoonal rainfall boosted viticulture and wheat production, though steppe drought cycles intensified nomadic incursions.

• River floods on the Danube and Maritsa structured transport calendars.

Societies and Political Developments

• First Bulgarian Empire:

  • After Peter I (r. 927–969), internal weakness and external pressures mounted.

  • Rus’ prince Sviatoslav invaded Bulgaria (968–971), capturing Preslav; Byzantine emperor John I Tzimiskes (r. 969–976) intervened, defeating Sviatoslav and annexing eastern Bulgaria (971).

  • Bulgarian resistance persisted in the western Balkans under the Cometopuli brothers; Samuel of Bulgaria (r. 997–1014) built a strong empire from Ohrid, challenging Byzantium across the Danube and Adriatic.

  • Basil II “Bulgar-Slayer” (r. 976–1025) waged relentless wars, culminating in the Battle of Kleidion (1014); by 1018, Bulgaria was fully absorbed into the Byzantine Empire.

• Byzantine Resurgence:

  • The Macedonian dynasty (Basil II, Constantine VIII) secured the Balkans after 1018, establishing themes (administrative districts) in Bulgaria and along the Danube.

  • Constantinople reasserted direct control over Thrace, Adrianople, and the Danubian marches, founding bishoprics and garrisons.

• Steppe Nomads:

  • Pechenegs dominated the Lower Danube steppe in the late 10th–11th centuries, raiding Byzantine and Bulgarian lands.

  • Byzantines suffered major defeats (e.g., Battle of Levounion, 1091) before defeating the Pechenegs with Cuman aid.

  • Cumans (Polovtsians) succeeded them as the principal nomads, raiding the Danube frontier by the late 11th century.

• Romania/Moldova (north of the Danube):

  • Slavic–Romance populations persisted under shifting suzerainties (Bulgarian, Byzantine, Pecheneg).

  • Autonomous principalities in Transylvania developed under Hungarian expansion after 1000.

• Northeastern Serbia / Croatia / Bosnia frontiers:

  • Tributary to Bulgaria, Byzantium, or Hungary in shifting intervals; local župans (chieftains) leveraged Danube–Sava junctions for trade and tribute.

Economy and Trade

• Agriculture: wheat, barley, oats, millet, and vines thrived in Thrace and the Danube valley; stock raising continued in mountain margins.

• Byzantine land system: after conquest of Bulgaria (1018), imperial fiscal registers (praktika) integrated Bulgar peasants into Byzantine tax law.

• Trade corridors:

  • Danube linked Rus’, Hungary, and the Balkans to Constantinople.

  • Via Militaris carried imperial armies and caravans.

  • Black Sea ports funneled wax, honey, grain, and slaves southward.

• Coinage: Byzantine nomismata circulated widely; regional markets expanded around Preslav, Adrianople, and Skopje.

Subsistence and Technology

• Fortifications: Byzantine rebuilt Preslav and fortified Sofia, Skopje, and Adrianople; Danube palisades defended ferries.

• Military systems: Byzantine cataphract cavalry and thematic infantry dominated post-1018; Bulgarians contributed levies. Steppe nomads relied on horse archery and deep raids.

• Literacy and scripts: Bulgarian monasteries sustained Cyrillic culture even under Byzantine control; scriptoria at Ohrid and Preslav produced hagiographies and law codes.

Movement and Interaction Corridors

• Danube crossings: Ruse, Silistra, and Vidin remained contested gateways for Pecheneg and Cuman incursions.

• Via Militaris tied Constantinople with Belgrade, essential for imperial supply.

• Carpathian passes opened Magyar access into Transylvania and the Danube plain.

• Black Sea shipping connected ports to Rus’ merchants and Byzantine markets.

Belief and Symbolism

• Orthodox Christianity:

  • Consolidated in Bulgaria under Boris and Simeon, then integrated into the Byzantine patriarchate after 1018.

  • Ohrid Archbishopric (granted autonomy by Basil II) preserved Slavic liturgy and Cyrillic texts.

• Bogomilism: Dualist heresy spread in 10th–11th centuries, critiquing wealth and hierarchy, enduring into Balkan medieval society.

• Byzantine Orthodoxy in Thrace and Macedonia reinforced Constantinople’s legitimacy; icons, relics, and churches marked the landscape.

Adaptation and Resilience

• Imperial absorption: Byzantine themes stabilized taxation and law in conquered Bulgaria.

• Nomad diplomacy: Byzantines alternated tribute, alliances, and military campaigns to manage Pechenegs and Cumans.

• Cultural resilience: Slavic literacy and ecclesiastical autonomy at Ohrid preserved Bulgarian identity under Byzantine rule.

• Military adaptation: recruitment of Pecheneg and Cuman auxiliaries allowed Byzantium to redirect steppe threats against rivals.

Long-Term Significance

By 1107 CE, Eastern Southeast Europe had been reshaped:

• Bulgaria was integrated into the Byzantine system, though Slavic identity and the Ohrid Archbishopric ensured cultural survival.

• Byzantium controlled Thrace and the Danube frontier, though constant steppe raids drained resources.

• Pecheneg collapse and Cuman rise altered the steppe balance.

• Hungary extended into Transylvania, shifting power north of the Danube.

This age defined the region’s Orthodox Christian character, embedded Cyrillic literacy, and hardened the Byzantine–steppe frontier dynamics that would endure until the Komnenian revival and the Second Bulgarian Empire in the late 12th century.

The Khazar city of Sarkel, a large limestone-and-brick fortress on the left bank of the lower Don River, had been built in 833 to protect the northwestern border of the Khazar state, when the Khazars had asked their ally, emperor Theophilus, for engineers to build them a fortified capital, and Theophilus had sent his chief engineer Petronas.

In recompense for these services, the Khazar khagan had ceded Chersonesos and some other Crimean dependencies to Constantinople.

The city serves as a bustling commercial center, as it controls the Volga-Don portage, which is used by the Rus to cross from the Black Sea to the Volga and thence to the Caspian; the route is known as the "Khazarian Way".

A garrison fortified at Sarkel includes Oghuz and Pecheneg mercenaries.

Around 965, Sviatoslav destroys Sarkel and possibly sacks (but does not occupy) the Khazar city of Kerch on the Crimea.

At Sarkel, Sviatoslav establishes a Rus' settlement called Belaya Vyezha ("the white tower" or "the white fortress", the East Slavic translation for "Sarkel").

The efforts of Kievan ruler Olga to bring Christianity to Russia are resisted by her son Sviatoslav, grand prince of Kiev from 945, who, after coming of age around 963, had begun a series of bold military expeditions, leaving his mother to manage the internal affairs of the Kievan state.

Sviatoslav is the son of Grand Prince Igor, who was himself probably the grandson of Rurik, prince of Novgorod.

Virtually nothing is known about his childhood and youth, which he spent reigning in Novgorod.

Sviatoslav's father, Igor, had been killed by the Drevlyans around 942.

The Russian Primary Chronicle says that Sviatoslav “sent messengers to the other lands announcing his intention to attack them.” Shortly after his accession to the throne, Sviatoslav had begun campaigning to expand the Rus' control over the Volga valley and the Pontic steppe region.

Between 963 and 965, he has attacked the Ossetes and Circassians in the northern Caucasus; …

…he has also attacked the Volga Bulgars.

Sviatoslav’s greatest success is the conquest of Khazaria, the Jewish state between the Volga and the Don, which for centuries has been one of the strongest states of Eastern Europe.

The sources are not clear about the roots of the conflict between Khazaria and Rus', so several possibilities have been suggested.

The Rus' had an interest in removing the Khazar hold on the Volga trade route because the Khazars collected duties from the goods transported by the Volga.

Historians have suggested that Constantinople may have incited the Rus' against the Khazars, who had fallen out with the Empire after the persecutions of the Jews in the reign of Romanus I Lecapenus.

Sviatoslav began by rallying the Khazars' East Slavic vassal tribes to his cause.

Those who would not join him, such as the Vyatichs, are attacked and forced to pay tribute to the Kievan Rus' rather than the Khazars.

Proceeding by the Oka and Volga rivers, he invades Volga Bulgaria and exacts tribute from the local population, thus bringing under Kievan control the upper Volga River.

He employs Oghuz and Pecheneg mercenaries in this campaign, perhaps to counter the Khazars' and Bulgars' superior cavalry.

Emperor Nikephoros sends to Sviatoslav his agent, Kalokyros, in 967 or 968 with the task of talking Sviatoslav into assisting Constantinople in a war against Bulgaria.

Sviatoslav is paid fifteen thousand pounds of gold and sets sail with an army of fifty thousand men, including thousands of Pecheneg mercenaries.

According to the Russian Primary Chronicle, while Sviatoslav was pursuing this campaign against the First Bulgarian Empire, the Pechenegs (in all probability, bribed by Nikephoros) invade Rus and besiege his capital of Kiev.

While the besieged suffer from hunger and thirst, Sviatoslav's general Pretich deploys his druzhina, his personal guard, on the opposite (left) bank of the Dnieper, not daring to cross the river against the larger Pecheneg force.

Sviatoslav's mother Olga of Kiev (who is in Kiev together with all of Sviatoslav's sons), reduced to extremes, contemplates surrender, if Pretich does not relieve the siege within one day.

She is anxious to send word about her plans to Pretich.

At last, a boy fluent in the Pecheneg language volunteers to venture from the city and urge Pretich to action.

Pretending to be a Pecheneg, he goes about their camp, as if searching for a lost horse.

When he attempts to swim across the Dnieper, the Pechenegs discover his subterfuge and start shooting at him, but to no avail.

When the boy reaches the opposite bank and informs Pretich about the desperate condition of the Kievans, the general decides to make a sally in order to evacuate Sviatoslav's family from the city, for fear of his sovereign's anger.

Early in the morning, Pretich and his troops embark on boats across the Dnieper, making great noise with their trumpets.

The besieged start cheering, and Olga ventures out of the city towards the river.

The Pechenegs, thinking that Sviatoslav is returning with his great army, lifts the siege.

The Pecheneg leader then decides to confer with Pretich and asks him whether he is Sviatoslav.

Pretich admits that he is only a general but warns the Pecheneg ruler that his unit is a vanguard of Sviatoslav's approaching army.

As a sign of his peaceful disposition, the Pecheneg ruler shakes hands with Pretich and exchanges his own horse, sword and arrows for Pretich's armor.

As soon as the Pechenegs retreat, Olga sends a letter to Sviatoslav reproaching him for his neglect of the family and people.

Upon receiving the message, Sviatoslav speedily returns to Kiev and thoroughly defeats the Pechenegs, who are still threatening the city from the south.
