Historical Context

The First Bulgarian Empire developed around the lower Danube after 681 and expanded across parts of the Balkans before Byzantine conquest in 1018. A restored Bulgarian state emerged from the revolt of 1185, with Tarnovo as its capital. Its rulers again pursued imperial authority before internal division and Ottoman expansion ended the principal centres of independent rule in the late fourteenth century.

The First Bulgarian Empire

The First Bulgarian Empire was established after the Bulgar-led forces of Asparuh crossed the Danube and defeated a Byzantine army. In 681, the Byzantine Empire recognized the new state and agreed to pay it tribute. The early polity included lands south of the Danube and north of the Balkan Mountains. Its position between the Danube, the Black Sea coast and the mountain routes into Thrace shaped both its defence and its dealings with Byzantium.

Territory changed with warfare, alliances and the strength of individual rulers. During the ninth and early tenth centuries, Bulgarian power extended into Thrace and Macedonia and, at its greatest reach, across parts of the middle Danube region and the western Balkans. The court moved from Pliska to Preslav in 893. Later, during the wars against Byzantium, the centres of government shifted westward. Campaigns and political changes repeatedly altered the state’s centres of authority.

The Second Bulgarian Empire

By 1018, Byzantine armies had brought the First Empire to an end. Byzantine rule lasted until the revolt led by Peter and Asen began in 1185. The brothers and their supporters established a new Bulgarian state, conventionally called the Second Bulgarian Empire, with its capital at Tarnovo. Under rulers such as Kaloyan and Ivan Asen II, it became a leading Balkan power. Later, conflicts with neighbouring states, internal struggles and the growth of regional lordships weakened central authority. Ottoman forces took Tarnovo in 1393 and Vidin in 1396, dates commonly used to mark the empire’s end. Bulgarian rulers and claimants continued to assert authority into 1422, but the extent and continuity of that later rule are disputed.

Geography

The lower Danube connected settlements on its banks and brought mounted allies from the northern steppe into Balkan politics. The Balkan Mountains separated northern plains from Thrace but also channelled movement through passes. Black Sea ports linked inland producers with maritime markets. These routes and barriers shaped where fortresses stood and which towns became valuable to rulers.

Rulers, officials and regional power

In the First Empire, the ruler led the army, conducted foreign relations and exercised judicial authority. The title changed over time: early rulers were known as khans, Boris I took the title knyaz, or prince, after his conversion to Christianity, and Bulgarian rulers used the title tsar, meaning emperor, from the early tenth century. In practice, royal authority depended on cooperation and competition with powerful aristocratic families. A council of nobles and armed men could be called to address major questions; in 766, such a council helped depose Khan Sabin after he sought peace with Byzantium.

Some senior offices joined military, diplomatic and administrative responsibilities. The kavhan , one of the leading officials of the First Empire, could command troops, advise the ruler and act as regent. Local administration developed as the territory expanded. Slavic communities initially retained some local leadership, but rulers increasingly appointed officials to govern regions and limit the independence of local groups.

The Second Empire adopted many titles and administrative practices from Byzantium. The tsar remained the highest authority, while a council of senior nobles and church leaders could advise on major matters. The aristocracy, commonly called bolyars, held regional offices, military commands and estates. Provincial divisions and governors changed as the state expanded or lost territory. Some powerful nobles acquired considerable autonomy, particularly during periods of weak or disputed rule. By the fourteenth century, separate centres such as Vidin and Dobruja further reduced the authority of the court at Tarnovo.

Law, authority and written documents

The later Byzantine Suda attributes laws to Krum through a moralising story about the fall of the Avars. It preserves his reputation as a lawgiver rather than an extant early ninth-century Bulgarian code. Christian compilations and royal grants provide different kinds of written legal evidence.

After the conversion to Christianity, a text known as the Court Law for the People set out rules for legal and religious conduct. It drew on Byzantine law but was adapted to a Slavic-language context. Its date and place of composition remain debated, so it should not be treated as a securely documented code issued by a named Bulgarian ruler. Its provisions, which include rules on testimony, property, marriage and religious practice, nevertheless show how Christian institutions and legal norms could be brought into the work of governing.

For the Second Empire, royal charters provide rare evidence of secular administration. A charter issued by Ivan Asen II after 1230 granted merchants from Dubrovnik permission to trade across his realm and named several regions under his authority. Other surviving charters record grants to monasteries and trading privileges. They show that royal commands could define rights and obligations, protect particular beneficiaries and express the ruler’s reach. They also preserve evidence of Middle Bulgarian, the language used in many documents of the period.

Agriculture

Agriculture supplied households, towns, armies and the court. Moesia, Thrace and parts of Macedonia produced cereals, grapes and other crops; livestock supplied food, fibre, traction and transport. Taxes and estate dues drew produce from cultivators, while monasteries and nobles accumulated rights over land and dependent people.

Farming remained central in the Second Empire. Grain production varied by region, while vineyards, orchards, vegetables and animal husbandry also contributed to local economies. Beekeeping supplied honey and wax, and forests provided timber. Mining and metalworking supported both household production and military needs. Urban and village crafts included pottery, weaving, leatherworking, carpentry and metalworking.

Trade

Trade connected the Bulgarian states with Byzantium, Central Europe, the Rus’ lands and communities around the Black Sea and Mediterranean. A treaty with Byzantium in 716 regulated aspects of commerce, including the use of state seals on goods. In 894, the transfer of the Bulgarian merchants’ market from Constantinople to Thessaloniki helped prompt war, illustrating how trading privileges could carry political weight. Under Ivan Asen II, the Dubrovnik charter offered merchants broad access to markets and routes across his territories. In the Second Empire, rulers also minted copper, silver and billon coins, while foreign currency continued to circulate. Such evidence shows an economy linked to long-distance exchange as well as local production, but one that remained rooted in agriculture.

Warfare, fortifications and state capacity

Warfare was a continuing responsibility for both empires. The First Empire’s early forces combined Bulgar cavalry with Slavic infantry. A mobile army could use ambushes, feigned retreats and knowledge of mountain passes, while fortifications protected routes and political centres. In the ninth century, Bulgarian rulers also developed siege capabilities, drawing on captured specialists and other expertise. Armies were not identical from one period to another: the balance of cavalry and infantry, available resources and the use of allies shifted with the political and military situation.

In the Second Empire, Cuman cavalry played an important role in some campaigns, alongside forces raised within the state and foreign soldiers. Fortresses were often placed on hills, plateaus and mountain routes. They could guard a pass, protect a town or provide refuge during a siege. The capital, Tarnovo, was defended by fortified hills and the difficult terrain of the Yantra River valley. Such defences could delay an enemy, but they could not replace coordination among rulers and regional commanders. The growing independence of local lords made it harder to organize a united response to successive invasions.

The Church

Christianity became the official religion of the First Empire under Boris I. The ruler’s baptism in 864 followed a period of diplomatic manoeuvring between Constantinople and Rome. Conversion offered a way to strengthen relations with Christian neighbours and to help integrate the empire’s different communities, but it also raised the question of who would control the Bulgarian Church. Around 870, Bulgaria obtained an autonomous archbishopric under the jurisdiction of Constantinople. In 893, Old Church Slavonic, also known in scholarship as Old Bulgarian, was adopted for church and state use. The Bulgarian Church’s patriarchal status was recognized by Byzantium in 927.

After the Byzantine conquest of 1018, the patriarchate was reduced to an archbishopric centred at Ohrid, but retained extensive privileges and dioceses. The uprising of 1185 brought a renewed effort to establish an independent Bulgarian Church. During the early Second Empire, rulers negotiated with both Rome and Constantinople. Kaloyan’s formal union with Rome did not replace Orthodox rites and practices. In 1235, the Bulgarian patriarchate was recognized at a church council. The church’s standing and territory remained closely connected to the political fortunes of the state.

Religious movements

Monasteries received estates and donations, maintained worship and supported books and teaching. Bogomilism emerged in the tenth century as a challenge to established religious authority. The cleric Cosmas describes followers rejecting church hierarchy, images and some practices while explaining creation through a dualist opposition between good and evil. His work sought to refute them. In 1211, Boril’s council condemned their teaching and entered the decision into a Synodikon used to proclaim Orthodoxy.

In the fourteenth century, another religious current, Hesychasm, gained influence in Bulgaria. It was an Eastern Orthodox tradition of contemplative prayer that sought inner stillness. The monk Gregory of Sinai helped spread its practice in the Balkans, and Theodosius of Tarnovo established a centre associated with it at the Kilifarevo Monastery. His circle connected monastic practice with translation and literary activity. Hesychasm was distinct from the movements condemned as heretical, even as church leaders worked to define and defend Orthodox teaching.

Writing, learning and literature

The arrival in Bulgaria of disciples of Cyril and Methodius in 886 helped establish a Slavic literary culture. The brothers had developed the Glagolitic alphabet for Christian texts and worship in Slavic. Their followers found support under Boris I and taught future clergy. Literary activity developed at centres associated with Preslav and Ohrid. Scholars translated religious works from Greek and composed original sermons, hymns, biographies of saints and polemical texts.

Royal patronage from the late ninth century strengthened the use of Old Church Slavonic, also called Old Bulgarian, in books and worship. Cyrillic developed within this literary world, with early inscriptions and manuscript traditions connecting it especially to northeastern Bulgarian centres. Glagolitic continued alongside it for a time. Translated books and trained clergy carried Christian teaching into other Slavic-speaking lands.

Literary production changed with political circumstances. The tenth-century cultural flowering under Simeon I included translations, original works and scholarly activity at Preslav and Ohrid. Following the conquest of 1018, this activity declined, though the use of Slavic writing did not disappear. Under the Second Empire, Tarnovo became a major literary centre. In the late fourteenth century, Patriarch Euthymius led efforts to revise and standardize written forms. His school produced religious works and translations, and its influence travelled beyond Bulgaria through scholars and clergy who worked in Serbia, Wallachia, Moldavia and Rus’ lands.

Architecture

Buildings expressed both the practical needs of government and the religious and cultural choices of rulers and patrons. Early Bulgarian centres included fortified royal and administrative spaces, churches and workshops. Pliska developed an extensive outer enclosure around a more heavily fortified inner zone. In Preslav, palaces, churches, monasteries and craft areas formed a more developed urban centre. After Christianity became official, church building expanded. The Great Basilica at Pliska and the domed Round Church at Preslav illustrate different forms of early Bulgarian religious architecture.

In the Second Empire, builders adapted regional materials and Byzantine influences to local needs. Churches often used alternating bands of stone and brick, with decorative niches and coloured ceramic elements on their exteriors. Fortifications tended to use the natural protection of hills, cliffs and river bends. At Tarnovo, the royal and patriarchal complexes occupied the fortified heights of Tsarevets. Elsewhere, churches, monasteries and defensive structures reflected local resources and the requirements of their communities.

Art

Painting and manuscript decoration joined religious imagery with expressions of patronage. Donors, known as ktitors , might be shown in church murals, linking their identity and generosity to a sacred setting. Surviving paintings at the Boyana Church include portraits of members of the ruling and aristocratic elite. The Tarnovo artistic tradition also appears in icons and illuminated manuscripts. The Gospel book commissioned by Ivan Alexander in 1355–1356, with hundreds of miniatures, is one example of the resources invested in courtly book production.

Fragmentation and the Ottoman conquests

The Ottoman advance reached the Balkans during a period of political division. By the mid-fourteenth century, the Bulgarian lands included rival or semi-independent powers as well as the court at Tarnovo. The rulers did not consistently cooperate with one another or with Byzantium. Ottoman forces, initially present as allies or hired troops in regional conflicts, established a lasting foothold in Europe and expanded through Thrace and the Balkan routes. The defeat of a Christian army at Chernomen in 1371 accelerated the pressure on Bulgarian territories.

Rulers responded through military resistance, diplomacy and, at times, vassalage. The ruler of Tarnovo, Ivan Shishman, recognized Ottoman overlordship during part of this struggle, while the ruler of Vidin, Ivan Sratsimir, pursued a separate policy. Ottoman forces took Sofia in the early 1380s, then besieged Tarnovo, which fell in 1393. Vidin was captured in 1396, after its ruler had briefly received the forces of a crusading army. The defeat of that army at Nicopolis in the same year ended any immediate prospect of restoring the wider state.

Vidin’s fall in 1396 supplies the conventional endpoint of the Second Empire. Constantine II, Ivan Sratsimir’s son, continued to bear the Bulgarian imperial title until his death in 1422. His claim and possible regional authority belonged to the unsettled aftermath of the main conquests, when Ottoman and neighbouring rulers competed for influence.
