List of Bulgarian monarchs

The monarchs of Bulgaria ruled Bulgaria during the medieval First and Second Bulgarian empires, as well as during the modern Principality and Kingdom of Bulgaria. This list includes monarchs from the establishment of the First Bulgarian Empire until modern times, omitting earlier mythical rulers as well as rulers of separate states such as Old Great Bulgaria and Volga Bulgaria.
Various titles have been used by the rulers of Bulgaria. The only recorded title, used before Bulgaria's conversion to Christianity, is kanasubigi, likely meaning "Khan, Lord of the Army" or "the sublime Khan". When Bulgaria converted to Christianity in the ninth century, the ruler Boris I was using the title knyaz. For much of its later history under the first and second empires, Bulgaria functioned as a multi-ethnic imperial state modelled on the neighbouring Byzantine Empire, which contributed to the adoption of the title of tsar by Bulgarian monarchs beginning with Simeon I in 913. Some powerful medieval Bulgarian rulers challenged Byzantine authority by proclaiming themselves as both Bulgarian and Roman emperors.
When Bulgaria re-emerged as a state in 1878 in the form of the Principality of Bulgaria, the rulers initially used the title knyaz since they were autonomous vassals of the Ottoman Empire and not fully independent. From Bulgaria's complete independence from the Ottomans in 1908 until the abolition of the monarchy in 1946, Bulgarian monarchs once more used the title tsar, though this time generally translated internationally as "king" rather than "emperor".

Titles

Titles in the First Bulgarian Empire (681–1018)

Evidence concerning the titles used by the rulers of the First Bulgarian Empire prior to the conversion to Christianity in the 860s is scant. The only title known from contemporary sources is kanasubigi, recorded in ten Greek-language inscriptions from the ninth century in reference to Omurtag and his son Malamir. Two gold medallions struck for Omurtag also use the same title.
Upon his conversion to Christianity in 864/865, Boris I adopted the new ruling title knyaz, generally translated as "prince". This title was used by the Bulgarian rulers until 913, when the knyaz Simeon I, Boris I's son, invaded the Byzantine Empire. Simeon aspired to make Bulgaria into the new "universal monarchy" by absorbing and replacing the empire centered in Constantinople. Due to the threat presented by Simeon, who reached the walls of Constantinople, the Byzantines relented and the Patriarch of Constantinople, Nicholas Mystikos, granted him an imperial crown. The only other monarch recognized as a basileus by the Byzantines was the Roman Emperor|Holy Roman emperor]. The Byzantines did not consider Simeon as outranking their own emperors and designated him as the "Emperor of the Bulgarians". Simeon himself used the grander title "Emperor of the Bulgarians and the Romans". The title of emperor was in Bulgarian translated as tsar, seen as equivalent to the Greek basileus or Latin imperator.
Bulgarian rulers from the death of Simeon I in 927 until the fall of the First Bulgarian Empire in 1018 used the simpler "Emperor of the Bulgarians", ceasing to claim Byzantium's universal monarchy.

Titles in the Second Bulgarian Empire (1185–1422)

The first rulers of the Second Bulgarian Empire revived the style used by Simeon I's successors, "Emperor of the Bulgarians", rendered tsr’ Bl’garom in Bulgarian documents and imperator Bulgarorum in Latin. The second empire's third ruler, Kaloyan, adopted the grander title "Emperor of Bulgarians and Vlachs". He unsuccessfully sought recognition of this title from the Papacy, though Pope Innocent III merely recognized him as "King of the Bulgarians and Vlachs", not wishing to recognize any other emperor than the Holy Roman emperor.
The fifth ruler of the second empire, Ivan Asen II after 1230 extended his original title "Emperor of the Bulgarians" to the grander "Emperor of the Bulgarians and Greeks". This title was taken to reflect his extensive conquests in formerly Byzantine territory and was effectively a revival of Simeon I's title since both "Greeks" and "Romans" were envisioned as referring to the inhabitants of the Byzantine Empire. Ivan Asen II also introduced the element "autocrat" into the Bulgarian imperial title, modelled on its usage in the Byzantine imperial title, and eventually in full styled himself as the "Emperor and Autocrat of the Bulgarians and Greeks".
Ivan Asen II's successors kept "autocrat" in the title but returned to the simpler style "Emperor and Autocrat of the Bulgarians". His extended title was later revived by Ivan Alexander, who also proclaimed himself as the "Emperor and Autocrat of the Bulgarians and Greeks" to challenge the authority of the then weakened Byzantine Empire. Ivan Alexander's son Ivan Shishman is also recorded to have used this extended imperial title.

Titles in modern Bulgaria (1878–1946)

The Tarnovo Constitution of the modern Principality of Bulgaria stipulated that the monarch was to use the title "Knyaz of Bulgaria" rather than tsar due to the principality being an autonomous vassal state of the Ottoman Empire rather than a fully independent country.
When Bulgaria achieved complete independence from the Ottoman Empire in 1908, the former knyaz Ferdinand I adopted the higher title of "Tsar of the Bulgarians", as had been used by Bulgarian monarchs in the Middle Ages. The assumption of the title of tsar was met with opposition from both the Ottomans and the Russian Empire. Although tsar had been understood as equivalent to emperor in medieval times, the title of the new Bulgarian tsars was generally translated as "King of the Bulgarians" internationally.

Names and regnal numbers

Regnal numbers for monarchs have only been officially used in Bulgaria in modern times, beginning with Alexander I in 1879. Modern historiography retroactively also assigns sequential regnal numbers to medieval Bulgarian rulers, even if they ruled different Bulgarian states and used different titles; Boris I ruled the First Bulgarian Empire as a prince, his great-grandson Boris II ruled the same state as emperor, and Boris III ruled the modern Kingdom of Bulgaria as tsar.
There were three different types of names used by medieval Bulgarian monarchs after Bulgaria converted to Christianity; names drawn from Bulgar or Slavic tradition, names drawn from Christian tradition, or double names combining both. When using a double name, the Christian name always preceded the name drawn from local tradition. Very rarely, Bulgarian rulers used double names combining two Christian names.
The use of double names by Bulgarian monarchs, sometimes not used consistently in contemporary sources, has in cases led to confusion and misunderstanding in modern efforts to assign regnal numbers. In particular, it has sometimes erroneously been assumed that the usage of double names indicated that the monarchs employed family names; this interpretation has in the past resulted in the use of names such as Ivan II Asen, George I Terter and Michael III Shishman. Names of clans were prominently used in Bulgaria in pre-Christian times, though disappeared from usage sometime after the conversion to Christianity, despite family names being used in some of Bulgaria's closest neighbours. Although names such as Asen or Terter could serve as genealogical and political markers to demonstrate a ruler's position in an illustrious lineage they were also fully part of the ruler's regnal names, as demonstrated by those rulers whose double names excluded genealogical connections. Double names with genealogical connotations were at times also claimed by rulers not belonging to the same dynastic lineage, such as Mitso Asen.

First Bulgarian Empire (c. 680–1018)

Early Bulgarian rulers (c. 680–803)

The First Bulgarian Empire is regarded to have been established 680 when the Bulgarian ruler Asparuh crossed the Danube. Asparuh's family, the Dulo clan, claimed descent from the Hunnic ruler Attila, through Attila's son Ernak. References to political developments within Bulgaria prior to the reign of Krum are extremely scant, making the dates and family relationships of the rulers recorded in contemporary and later sources highly uncertain. The rulers below may all belong to the Dulo clan or might alternatively have belonged to various competing clans. Several alternate chronologies of early Bulgarian rulers have been proposed, with some presented below, with the names standardized across sources:

House of Krum (803–997)

Image	Name	Reign	Succession and notes
	Krum Крум	803?–814	Possibly a descendant of the Dulo clan. Krum may have ascended the throne as early as 796/7. Successful warrior and conqueror; defeated the Avars and incorporated parts of Transylvania and eastern Serbia into Bulgaria. Replaced customary law in Bulgaria with written legislation. Most known for his wars against the Byzantine Empire. In 811 his forces defeated and killed Emperor Nikephoros I at the Battle of Pliska, whereafter the emperor's skull was fashioned into a drinking cup. Died suddenly while preparing a campaign intended to conquer Constantinople.
	Dukum Дукум	possibly 814	Brother of Krum. An experienced military commander who played an important role in Krum's military campaigns. Possibly seized the throne after Krum's death but died almost immediately, presumably of natural causes. Some historians consider Dukum, named only in hagiographical sources, merely a local ruler and not a monarch, with Krum perhaps being succeeded directly by his son Omurtag.
	Ditzeng Диценг	possibly 814–815	Unknown relation; presumably a brother or nephew of Krum. Recorded as persecutor of Christian prisoners. May have been in ill health at the time of his accession. Some historians consider Ditzeng, named only in hagiographical sources, merely a local ruler and not a monarch, with Krum perhaps being succeeded directly by his son Omurtag.
	Omurtag Омуртаг	814/815–831	Son of Krum. May have seized the throne from Ditzeng or succeeded his father Krum directly. Signed a 30-year peace treaty with the Byzantine Empire in 815. Devoted much of his reign to construction projects. At times aided the Byzantines, such as joining the war against the Byzantine pretender Thomas the Slav. Solidified the Bulgarian central government.
	[Malamir of Bulgaria\|Malamir] Маламир	831–836	Son of Omurtag. Malamir was possibly underage throughout his reign and the Bulgarian administration was headed by the regent Isbul. His five-year reign saw renewed conflict and warfare with the Byzantine Empire. Died of unknown causes, no longer occupying the Bulgarian throne by 836.
	Presian I Пресиян	836–852	Son of Zvinitsa, a son of Omurtag. Underage at the time of his accession, the administration was initially headed by the regent Isbul. Although hostile to the Byzantine Empire, Presian spent the better part of his reign working to expand Bulgaria rather than fighting the Byzantines. His reign saw the Bulgarians push west of the Vardar river for the first time and led to considerable territorial gains in the west.
	Boris I Борис	852–889	Son of Presian I. Unsuccessfully warred against Serbia and Croatia. Under pressure from the Byzantine emperor Michael III, Boris was responsible for converting Bulgaria to Christianity, he himself being baptized in 864/865. Adopted the new ruling title of knyaz at the time of his conversion. Defeated a major uprising of pagans against his rule. Abdicated in favour of his son Vladimir in 889 and retired to a monastery, dying in 907. Considered a saint in the Eastern Orthodox Church.
	[Vladimir of Bulgaria\|Vladimir] Владимир Расате	889–893	Son of Boris I. The Bulgarian nobility revolted against Christianity after Boris's abdication and Vladimir took part in persecuting Christians and destroying churches. Also abandoned relations with the Byzantine Empire. Boris returned from retirement in 893 and deposed, blinded, and imprisoned Vladimir. Boris's other son Simeon was thereafter made ruler.
	Simeon I Симеон	893–927	Son of Boris I. Made knyaz after the deposition of Vladimir. Aspiring to supplant or conquer the Byzantine Empire, Simeon was in 913 the first Bulgarian ruler to assume the title of tsar and was recognized as such by the Byzantines. Fought many wars with the Byzantine Empire, though never succeeded in capturing Constantinople. Extended Bulgarian rule far into Macedonia, Albania, and Serbia but appears to have lost the Bulgarian lands north of the Danube. Proclaimed the Bulgarian Orthodox Church to be independent under its own patriarch.
	Peter I Петър	927–969	Son of Simeon I. Faced invasions from the Magyars and uprisings by some of his brothers. Otherwise had a relatively peaceful reign; achieved important diplomatic gains from the Byzantines, such as the recognition of his imperial title, the recognition of the Bulgarian church's independence, and an imperial marriage. Abdicated and retired to a monastery in 969 after suffering a stroke. Considered a saint in the Bulgarian Orthodox Church.
	Boris II Борис	969–977	Son of Peter I. Contended with invasions by the Kievan Rus' and the Byzantine Empire. The Bulgarian capital of Preslav was captured by the Byzantine Empire in 971, resulting in Boris and his brother Roman being brought to Constantinople as prisoners. Power in Bulgaria fell to a group of four nobles, the cometopuli brothers, who upheld the rights of Boris while he was held prisoner. The two brothers escaped back to Bulgaria in 977, though Boris was killed during the journey.
	Roman Роман	977–997	Son of Peter I. Previously held captive by the Byzantines in Constantinople. Infrequently mentioned in surviving sources and appears to have been more of a figurehead for the cometopuli than an active ruler. Captured by the Byzantines again in 991 and died in captivity six years later.

Pretenders during Byzantine rule (1018–1185)

Various Byzantine military governors were appointed in formerly Bulgarian lands over the course of the Byzantine conquest of Bulgaria, from the 970s onwards. Following the completion of the conquest of Bulgaria in 1018, Emperor Basil II organized much of the central Balkans into the Theme of Bulgaria, which was governed by an imperially appointed official titled as the doux or katepano of Bulgaria. The capital of Byzantine Bulgaria was Skopion. There were several attempts at restoring the Bulgarian Empire during the nearly two centuries of Byzantine rule.

	Presian II Пресиян	1018	Son of Ivan Vladislav. Although most of the Bulgarian aristocracy surrendered to the Byzantine Empire alongside Maria, Presian II and some of his brothers continued to lead a small resistance, based around the Tomorr mountain range. They were eventually also forced to surrender to the Byzantines.
	Peter Delyan Петър Делян	1040–1041	Claimed to be a grandson of Gavril Radomir, though his ancestry is unverified.

Believed to have been murdered.
	Boril Борил	1207–1218	Son of a sister of Peter II, Ivan Asen I and Kaloyan. Boril's reign saw unsuccessful wars against Serbia, the Latin Empire, and the competing successor states of the Byzantine Empire, as well as the spread of the Bogomilist sect in Bulgaria. Deposed and blinded by his cousin Ivan Asen II.
	Ivan Asen II Иван Асен	1218–1241	Son of Ivan Asen I. Overthrew Boril. Ivan Asen II aspired to make himself the ruler of a joint Bulgarian-Byzantine Empire and his reign saw the Second Bulgarian Empire reach its greatest extent.

	Kaliman Asen II Калиман Асен	1256	Grandson of Ivan Asen I. Proclaimed emperor after Michael Asen I's death. Married his predecessor's widow but was ineffective at maintaining power and died within a year. His death extinguished the male line of the House of Asen.

Successors of the Asenids (1256–1280)

The end of the male line of the House of Asen plunged Bulgaria into a chaotic period of fragmentation and civil wars between numerous lines of claimants.

Image	Name	Reign	Succession and notes
	Mitso Asen Мицо Асен	1256–1263	Husband of Maria Asenina, a daughter of Ivan Asen II. Proclaimed emperor in southeastern Bulgaria either in opposition to Kaliman Asen II or after his death.

Image	Name	Reign	Succession and notes
	George Terter I Георги Тертер	1280–1292	Leading member of the Bulgarian aristocracy. Wishing to safeguard the position of Ivan Asen III, the Byzantine emperor Michael VIII Palaiologos arranged for George Terter to divorce his wife and marry Maria Asenina of Bulgaria\|Kira Maria Asenina].

Image	Name	Reign	Succession and notes
	Chaka Чака	1299–1300	Son-in-law of George Terter I and son of Nogai Khan of the Golden Horde. Invaded Bulgaria, assisted by Theodore Svetoslav. Proclaimed himself as emperor of Bulgaria and achieved some recognition with Svetoslav's help. Came into conflict with the Golden Horde khan Toqta and then overthrown and strangled by Svetoslav. Some historians have argued that Chaka was never emperor of Bulgaria, but merely dominated it through his brother-in-law Theodore Svetoslav.

House of Terter (1300–1323, second time)

Image	Name	Reign	Succession and notes
	Theodore Svetoslav Тодор Светослав	1300–1322	Son of George Terter I; previously junior co-emperor 1285–1292. Overthrew and strangled Chaka, with support from Toqta of the Golden Horde.

After his deposition, Ivan Stephen fled to Serbia and then to the Byzantine Empire.

House of Sratsimir (1331–1422)

The rulers of the House of Sratsimir, patrilineal descendants of the despot Sratsimir, are in lists of monarchs often designated as part of the Shishmanid dynasty, with which they only share matrilineal descent. Through their matrilineal descent from the House of Shishman, the rulers of the House of Sratsimir were also descendants of the House of Asen.

Pretenders during Ottoman rule (1422–1878)

Following the gradual conquest of Bulgaria in the 14th and 15th centuries, the Ottomans incorporated the Bulgarian lands into the vast province of Rumelia. In the late 16th century, the new province of Silistra was created due to persistent northern attacks from the Cossacks. Later on, much of modern-day northern Bulgaria was organized into the Danube vilayet, which in terms of borders closely corresponded to the succeeding autonomous Principality of Bulgaria. Like under the period of Byzantine rule, the Ottoman authorities were sometimes faced with Bulgarian uprisings aimed at independence, at times also involving the proclamation of new Bulgarian monarchs.

Image	Name	Reign	Succession and notes
	Fruzhin Фружин	1422–1460	Son of Ivan Shishman. Fled to Hungary after the fall of the Second Bulgarian Empire, where he was made the ruler of the County of Temes.

The first National Assembly elected Alexander of Battenberg, a German prince, as monarch. Since Bulgaria was stipulated to remain an autonomous vassal state of the Ottoman Empire, Alexander used the title knyaz rather than tsar. Deposed in a coup d'état\|coup] led by pro-Russian army officers. Briefly reinstated following a counter-coup before abdicating the throne.

House of Saxe-Coburg and Gotha (1887–1946)

Image	Name	Reign	Succession and notes
	Ferdinand I Фердинанд I	7 July 1887 – 3 October 1918	Chosen as knyaz after Prince Valdemar of Denmark declined the throne after being approached. Secured Bulgaria's complete independence from the Ottoman Empire in 1908, whereafter he adopted the style of tsar. Leading figure in the First Balkan War though Bulgaria's actions after victory led to the Second Balkan War which deprived the country of most of its gains. Aligned with the German Empire in World War I and was forced to abdicate after the war's conclusion.
	Boris III Борѝс III	3 October 1918 – 28 August 1943	Son of Ferdinand I. Succeeded to the throne after his father's abdication. Bestowed near-dictatorial powers by a pro-monarchical regime in 1935. Aligned with Nazi Germany during World War II, mainly out of a desire to increase Bulgarian territory. Bulgaria participated in the invasions of Yugoslavia and Greece, though Boris refused to send Bulgarian soldiers to aid the German invasion of Russia. His government oversaw the Holocaust in Bulgaria. Died in mysterious circumstances shortly after a visit to Adolf Hitler.
	Simeon II Симеон II	28 August 1943 – 15 September 1946	Son of Boris III.
