The monarchs of Bulgaria ruled Bulgaria during the medieval First ( 681–1018) and Second (1185–1396) Bulgarian empires, as well as during the modern Principality (1878–1908) and Tsardom(Kingdom) (1908–1946) 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 (852–889) was using the title knyaz (prince). which contributed to the adoption of the title of tsar (emperor) by Bulgarian monarchs beginning with Simeon I (893–927) in 913.
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.
Upon his conversion to Christianity in 864/865, Boris I (852–889) adopted the new ruling title knyaz, generally translated as "prince" (though sometimes alternatively as "king"). This title was used by the Bulgarian rulers until 913, when the knyaz Simeon I (893–927), Boris I's son, invaded the Byzantine Empire. Simeon aspired to make Bulgaria into the new "universal monarchy" (a role the Byzantines viewed themselves as having) 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 (i.e. emperor) by the Byzantines was (at times) the 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".
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. The second empire's third ruler, Kaloyan (1196–1207), adopted the grander title "Emperor of Bulgarians and Vlachs" (imperator Bulgarorum et Blachorum). He unsuccessfully sought recognition of this title from the Papacy, though Pope Innocent III merely recognized him as "King of the Bulgarians and Vlachs" (rex Bulgarorum et Blachorum), not wishing to recognize any other emperor than the Holy Roman emperor. His extended title was later revived by Ivan Alexander (1331–1371), who also proclaimed himself as the "Emperor and Autocrat of the Bulgarians and Greeks" Ivan Alexander's son Ivan Shishman (1371–1395) is also recorded to have used this extended imperial title. Although tsar had been understood as equivalent to emperor in medieval times,
Names and regnal numbers

Regnal numbers for monarchs have only been officially used in Bulgaria in modern times, beginning with Alexander I in 1879. Asparuh's family, the Dulo clan, claimed descent from the Hunnic ruler Attila, through Attila's son Ernak.

Pretenders during Byzantine rule (1018–1185)
Various Byzantine military governors (with the title strategos) 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 (depending on the time) as the doux (duke) or katepano of Bulgaria. The capital of Byzantine Bulgaria was Skopion (modern-day Skopje).
