1.The name and its meanings
The word appears in the forms knez, knyaz, knaz, and other closely related variants. It originally denoted a tribal leader and is generally traced to a very early Germanic loan associated with contacts between the Slavs and East Germanic peoples, probably the Goths. Its meanings subsequently developed in different ways across the Slavic languages. Unlike many offices of the Second Bulgarian Empire, the knez has no established Byzantine prototype: the designation is Slavic, although the presumed official operated in an administrative setting strongly influenced by Byzantium.
In medieval texts connected with Bulgaria, knyaz is not always the name of an office. The Thessalonian Legend and a hagiographic work from the Lesnovo tradition use it for rulers. The Serbian archbishop Danilo similarly calls Strez and the lord of Vidin, Shishman, knezes, but these references do not prove that either man officially held a princely title. Strez is attested as a sebastokrator, while Shishman is not independently identified as a knez. This usage instead reflects Serbian terminology, in which a knez could often be a ruler. The word was not characteristic of late medieval Bulgaria as a sovereign title.
The term also had the broad social meaning of lord, notable, powerful man, or wealthy person. Patriarch Euthymios, for example, calls the Archangel Michael the “knez over the people of God.” Other literary works place knezes among lords and nobles or contrast them with the poor. Such examples demonstrate the word’s general vocabulary meaning, not a position in the hierarchy of the state.
2.The Bulgarian evidence
The only Bulgarian testimony that appears clearly institutional is the Virgin Charter. Its immunity clauses—provisions forbidding state officials from interfering with monastic property—mention the knez twice. In one list he follows sebastoi, holders of a Byzantine honorific dignity, and praktors, officials associated with revenue collection. In another he comes after a sebastos, doux, kastrophylax, and praktor; the doux was a senior provincial governor, while the kastrophylax was responsible for a fortress. This points to a functionary in the local administration, but his position in such lists does not provide a secure scale of rank.
Several narrative references are even less clear. An Osogovo hagiography speaks of “local knezes,” while another account mentions Knez Damyan, who became a monk and remained at the Seven Thrones Monastery. These figures were most probably provincial notables rather than holders of a precisely defined state office. Consequently, no individual is securely known to have held the Bulgarian office of knez during the Second Empire.
3.Parallels and continuation
The closest parallels come from medieval Serbia, where knezes undoubtedly took part in local government. In a charter of King Stefan Dušan from 1334, the phrase “knez of my kingdom” designates a representative of royal authority and distinguishes him from ordinary lords. A document issued by Konstantin Dragaš on 26 March 1388 places the knez alongside the kephale, the governor of a district or town, as an organ of justice. King Stefan Uroš II Milutin’s charter of 1300 for the Monastery of St George near Skopje also mentions a “knez of the župa,” linking the office to the župa, a local administrative district. The Serbian knez seems to have occupied a clearer and probably stronger position than the functionary named in the Virgin Charter.
The designation was also widespread north of the Danube, but its use there does not provide a direct model for Bulgaria. In Wallachia and Moldavia it came to denote members of a social stratum below the boyars but above the common people, and later free persons or landowners. This development differs from the presumed administrative office in the Bulgarian lands.
Knezes are much better documented after the Ottoman conquest, especially in the northwestern Bulgarian regions. The knez was generally a village headman and an intermediary between the population and the Ottoman authorities. A law concerning the knezes and primikurs of the Vidin region required them to assist with tax collection, track down members of the reaya—the tax-paying population—who had fled, and return them. The office had pronounced administrative and policing functions. In practice it passed from father to son, while its holders enjoyed a degree of protection from the authority of the sanjakbey and received privileges in return for their duties.
The Ottoman law treats knezes and primikurs together without clearly explaining the difference between them. Later descriptions, however, place knezes among persons holding timars—rights to designated revenues in return for service—whereas primikurs and their relatives principally received tax exemptions. Evidence from Bosnia also records a Vlach knez in command of dozens of primikurs. This suggests that the knez occupied the higher position in the later system, but it does not prove that the same relationship existed in the thirteenth or fourteenth century.
A distinctive case is Knez Fruzhin, recorded in the fifteenth century with his sons Stoyan, Stoyko, and Stanislav between Svrljig and Şehirköy. As members of the service category known as müsellems, they were required to provide people to guard a mountain pass. Their unusual duties and the exceptional spelling of the title suggest that they belonged to the local Christian aristocracy. The proposal that Fruzhin was the son of Tsar Ivan Shishman is attractive but cannot be demonstrated. A marginal note from Kratovo calling another holder “Lord Knez Dimitar” shows that the designation could retain considerable prestige even under Ottoman rule.
4.The central problem
The status of the Virgin Charter remains the central problem. It cannot be accepted unconditionally as an authentic Bulgarian royal act, and it may be a reworking connected with Milutin’s charter of 1300 for the same monastery. Both texts contain the recurring combination sebastos–praktor–knez, but their full lists of officials and the order in which they appear differ substantially. There is therefore no proof of mechanical copying, although it remains possible that a Serbian institution was introduced into a supposedly Bulgarian text.
The continuation of the office under Ottoman rule points to a local tradition and is the strongest argument that it may also have existed before the conquest. Against this stands the near-total absence of secure Bulgarian documents and the concentration of the later evidence in the northwestern lands, where Serbian influence was particularly strong. No seals, coins, clothing, or other insignia of Bulgarian knezes are known. It is therefore impossible to determine the office’s precise origin and rank in the Second Empire or the moment of its disappearance; even its presence in the contemporary administrative structure remains plausible but problematic.
The word appears in the forms knez, knyaz, knaz, and several other closely related variants. It first meant a tribal leader. Scholars usually connect it to a very early Germanic loan word that came from contacts between the Slavs and East Germanic peoples, most likely the Goths. Over time, its meaning changed in different ways in the Slavic languages. Unlike many offices of the Second Bulgarian Empire, the knez had no clear Byzantine model. The word itself was Slavic, even though the official who may have held it worked in an administrative world deeply shaped by Byzantium.
In medieval texts about Bulgaria, knyaz does not always mean an official office. The Thessalonian Legend and a hagiographic work from the Lesnovo tradition use it for rulers. The Serbian archbishop Danilo also calls Strez and the lord of Vidin, Shishman, knezes. But these passages do not show that either man officially held a princely title. Strez is known as a sebastokrator, and Shishman is not separately identified as a knez. These uses reflect Serbian language habits, where a knez could often mean a ruler. The word was not a normal sovereign title in late medieval Bulgaria.
The term also had a wider social meaning: lord, notable person, powerful man, or wealthy man. Patriarch Euthymios, for instance, calls the Archangel Michael the “knez over the people of God.” Other literary texts place knezes among lords and nobles, or contrast them with the poor. These examples show the word’s general meaning in everyday use, not a fixed place in the state hierarchy.
The only Bulgarian evidence that looks clearly institutional is the Virgin Charter. In its immunity clauses—rules that forbid state officials from interfering with monastic property—the knez is mentioned twice. In one list he comes after sebastoi, who held a Byzantine honorific rank, and praktors, officials linked to collecting revenue. In another list he follows a sebastos, a doux, a kastrophylax, and a praktor. The doux was a senior provincial governor, and the kastrophylax was in charge of a fortress. This suggests a local administrative official, but the order of the names does not let us fix his exact rank with confidence.
Other narrative references are even less certain. An Osogovo hagiography speaks of “local knezes,” and another account mentions Knez Damyan, who became a monk and stayed at the Seven Thrones Monastery. These men were most likely provincial notables, not holders of a sharply defined state office. For that reason, no person can be securely shown to have held the Bulgarian office of knez during the Second Empire.
The best parallels come from medieval Serbia, where knezes clearly took part in local government. In a charter of King Stefan Dušan from 1334, the phrase “knez of my kingdom” refers to a representative of royal power and sets him apart from ordinary lords. A document issued by Konstantin Dragaš on 26 March 1388 places the knez alongside the kephale, meaning the governor of a district or town, as part of the justice system. King Stefan Uroš II Milutin’s charter of 1300 for the Monastery of St George near Skopje also mentions a “knez of the župa,” linking the office to the župa, a local administrative district. The Serbian knez seems to have had a clearer, and probably stronger, position than the official named in the Virgin Charter.
The title was also common north of the Danube, but that does not give a direct model for Bulgaria. In Wallachia and Moldavia, knez came to mean a social group below the boyars but above ordinary people, and later free persons or landowners. That development is different from the presumed administrative office in Bulgarian lands.
Knezes are much better documented after the Ottoman conquest, especially in the northwestern Bulgarian regions. There the knez was usually a village headman and a go-between for the people and the Ottoman authorities. A law about the knezes and primikurs of the Vidin region ordered them to help collect taxes, find members of the reaya—the tax-paying population—who had run away, and bring them back. The office had strong administrative and policing duties. In practice it passed from father to son. Its holders also had some protection from the sanjakbey and received privileges in return for their work.
The Ottoman law treats knezes and primikurs together without clearly explaining how they differed. Later accounts, however, place knezes among people who held timars—rights to specific revenues in return for service—while primikurs and their relatives mainly received tax exemptions. Evidence from Bosnia also mentions a Vlach knez in command of dozens of primikurs. This suggests that the knez held the higher position in the later system, but it does not prove that the same arrangement existed in the thirteenth or fourteenth century.
One unusual case is Knez Fruzhin, recorded in the fifteenth century with his sons Stoyan, Stoyko, and Stanislav between Svrljig and Şehirköy. As members of the service group called müsellems, they had to provide men to guard a mountain pass. Their unusual obligations and the unusual spelling of the title suggest that they belonged to the local Christian aristocracy. The idea that Fruzhin was the son of Tsar Ivan Shishman is appealing, but it cannot be proved. A marginal note from Kratovo that calls another holder “Lord Knez Dimitar” shows that the title could still carry real prestige under Ottoman rule.
The status of the Virgin Charter remains the main problem. It cannot simply be accepted as a genuine Bulgarian royal document, and it may instead be a later reworking connected with Milutin’s charter of 1300 for the same monastery. Both texts include the repeated sequence sebastos–praktor–knez, but their full lists of officials and the order of those lists are quite different. There is no proof of direct copying, although it is still possible that a Serbian institution was inserted into what is presented as a Bulgarian text.
The survival of the office under Ottoman rule points to a local tradition, and that is the strongest reason to think it may also have existed before the conquest. Against this stands the near total lack of secure Bulgarian documents and the fact that the later evidence is concentrated in the northwestern lands, where Serbian influence was especially strong. No seals, coins, clothing, or other marks of Bulgarian knezes are known. For that reason, we cannot determine exactly where the office came from, what rank it had in the Second Empire, or when it disappeared. Even its place in the administrative system of the time remains possible, but uncertain.
Knez was a Slavic word for a leader or important man. In medieval Bulgaria, it was sometimes used for rulers or nobles, but not clearly as a fixed state office. Most of the time, it was just a general word for a lord or a wealthy, powerful person.
Only one Bulgarian text seems to show knez as an official job, but even that source is doubtful. Because of this, historians cannot prove that a real Bulgarian office of knez existed in the Second Bulgarian Empire, or say exactly how high its rank was.
Clearer examples come from Serbia, where knezes did local government work in the 1300s. After the Ottoman conquest, the title is well known in Bulgaria as a village headman who helped collect taxes and kept order. This shows the word lasted a long time, but its early Bulgarian form is still uncertain.
