Miloš Obilić (, ) is a legendary Serbian knight and saint in the Serbian Orthodox Church traditionally said to have served Prince Lazar during the Ottoman invasion of Serbia in the late 14th century. Although absent from contemporary records, he features prominently in later accounts of the 1389 Battle of Kosovo as the assassin of Sultan Murad I. The assassin remains unnamed in historical sources until the late 15th century, but the widespread circulation of the story in Florentine, Serbian, Ottoman, and Greek sources suggests that versions of it were known across the Balkans within decades of the battle.
His original name is believed to have been Miloš Kobilić, though multiple variations exist in historical sources, and his actual existence remains uncertain. The Lazar dynasty, consolidating its power, gave birth to the Kosovo Myth, which incorporated the legend of Obilić. Jelka Ređep notes that Obilić's legend significantly evolved through oral tradition, reflecting Serbian cultural ideals of heroism, loyalty and sacrifice. Over time, he became a central figure in Serbian epic poetry, where he was elevated to the status of a national hero embodying medieval Serbian folklore. Alongside Prince Lazar’s martyrdom and the alleged treachery of Vuk Branković, Miloš's deed became integral to Serbian narratives surrounding the Battle of Kosovo. By the 19th century, he was also venerated as a saint in the Serbian Orthodox Church.
Miloš Obilić also appears in Albanian epic poetry, where he is remembered as Millosh Kopiliqi, with his birthplace traditionally linked to the Drenica region in modern-day Kosovo, where villages named Kopiliq still exist. However, there is no definitive evidence confirming the identity of Murad’s assassin.
Name Miloš is a Slavic given name recorded from the early Middle Ages among the Bulgarians, Czechs, Poles and Serbs. It is derived from the Slavic root mil-, meaning "merciful" or "dear", which is found in a great number of Slavic given names.
Several versions of the hero's surname have been used throughout history. His original surname was Kobilić or Kobilović, a thesis which is further supported by archival findings by historian Mihailo Dinić in Ragusan archives of 1433 which show that Miloš's original surname was indeed Kobilić (). In Albanian folklore, the original name is preserved and he is known as Kopiliq. The root of the name 'Kopiliq' might be in an old Balkan substrat word, in Albanian kopil (child or bastard child), in Romanian copil (child) and in Serbian kopile (bastard child) or kobila (mare, from which kobilić, son of the mare). The etymological origin of his name is indicated in Serbian folk stories which claim that the hero is said to have been nursed by a mare. Jireček connected the surname to two noble families in medieval Ragusa and Trebinje, the Kobilić and Kobiljačić in the 14th and 15th centuries, and noted that they altered their surnames in the 18th century because they considered it "indecent" to be associated with mares. A poem by Croat Andrija Kačić Miošić titled Pisma od Miloscia Cobilichja i Vuka Brancovichja (Pisma od Kobilića i Vuka Brankovića, modern spelling) preserves the old name in the 18th century.
The rendering Obilić has universally been used by Serbian writers in modern times. Its first version is found in the History of Montenegro (1754) by Vasilije Petrović, who wrote of one Miloš Obilijević, and in 1765, the historian Pavle Julinac who rendered the surname as Obilić. According to Czech historian Konstantin Jireček, the surname Obilić and its different renderings are derived from the Serbian words obilan ("plenty of") and obilje ("wealth, abundance").:
Miloš is often referred to in the epic poems as "Miloš of Pocerje", and according to local legends, he came from the western Serbian region of Pocerina. In Pocerina there is a spring known as "Miloševa Banja" (Miloš's spring) and an old grave that is claimed to be the grave of Miloš's sister.
Literary sources The earliest sources on the Battle of Kosovo, which generally favour the cult of Prince Lazar, do not mention Miloš or his assassination of the sultan. The assassination itself is first recorded by Deacon Ignjatije on 9 July 1389, only 12 days after the battle. The assassination of sultan Murad and one of his sons (Yakub Çelebi) was also mentioned in the instructions of the Venetian Senate issued to Andrea Bembo on 23 July 1389, although Venetians were uncertain if news about the assassination were true. On 1 August 1389 King Tvrtko I of Bosnia (r. 1353–1391) wrote a letter to Trogir to inform its citizens about the Ottoman defeat. Victory over the Turks () was also reported by Coluccio Salutati (died 1406), Chancellor of Florence, in his letter to King Tvrtko, dated 20 October 1389, on behalf of the Florentine Senate. The killer is not named but he is described as one of twelve Christian noblemen who managed to break through the Ottoman ranks:
"Fortunate, most fortunate are those hands of the twelve loyal lords who, having opened their way with the sword and having penetrated the enemy lines and the circle of chained camels, heroically reached the tent of Amurat [Murad] himself. Fortunate above all is that one who so forcefully killed such a strong vojvoda by stabbing him with a sword in the throat and belly. And blessed are all those who gave their lives and blood through the glorious manner of martyrdom as victims of the dead leader over his ugly corpse."Emmert cites V.V. Makušev, "Prilozi k srpskoj istoriji XIV i XV veka," Glasnik srpskog ucenog društva 32 (1871): pp. 174–5.
Scholars consider many details in Tvrtko's letter to be fanciful, including the symbolic number 12.
In 1402, an anonymous Catalan author assigned Murad's death to a Hungarian knight. The knight might have been related to Lazar through marriage and had sent a Hungarian contingent to the battle. In the legend, Miloš Obilić was Lazar's son-in-law; in reality, Lazar had a Hungarian son-in-law. Another Italian account, Mignanelli's 1416 work, asserted that it was Lazar who killed the Ottoman sultan.
The assassin's first appearance in Serbian sources is in the biography of Stefan Lazarević, Lazar's son, by Constantine the Philosopher, written in the 1440s. The hero, still anonymous, is described as a man of noble birth whom envious tongues had sought to defame before the prince. To prove his loyalty and courage, he left the front line on the pretext of being a deserter, seized the opportunity to stab the sultan to death and was killed himself shortly afterwards. The initial phase of ignominy and its redemption by a courageous plot of slaying the sultan are narrative ingredients which would become essential to the Serbian legend as it evolved in later times.
The loss of the Sultan also made an impression on the earliest Ottoman sources. They usually describe how Murad was unaccompanied on the battlefield and an anonymous Christian who had been lying among the corpses stabbed him to death. In the early 15th century, for instance, the poet Ahmedi writes that "[s]uddenly one of the Christians, who was covered in blood and apparently hidden among the enemy dead, got up, rushed to Murad and stabbed him with a dagger."Ahmedi, ed. Olesnicki, "Turski izvori o Kosovskom bo ju."Glasnik skopskog naucnog drustva 14 (1934): 60–2, as cited by Emmert.
Halil İnalcık explained that one of the most important contemporary Ottomans sources about the Battle of Kosovo is the 1465 work of Enveri (). İnalcık argued that it was based on the testimony of a contemporary eyewitness of the battle, probably Hoca Omer, an envoy sent by the Sultan to Lazar before the battle. In this work Enveri explains that before he became a Serbian nobleman, Miloš (Miloš Ban is how İnalcık rendered the name in Enveri's text) was a Muslim at the Sultan's court who deserted Ottomans and abjured Islam. The Sultan allegedly called him to return to his service many times. Enveri explains that although Miloš always promised to return, he never did. According to this account, when Lazar was captured, Miloš approached the Sultan who was riding a black stallion and said: "I am Miloš Ban, I want to go back to my Islamic faith and kiss your hand." When Miloš came close to the Sultan, he struck him with the dagger hidden in his cuff. The Sultan's men cut Miloš into pieces with swords and axes.
One historian from Edirne, Oruc Bey, explains the lack of protection by saying that the army was preoccupied with pursuing the enemy in rear flight and introduces an element of deception: the Christian "had promised himself as a sacrifice and approached Murad, who was sitting alone on his horse. Pretending he wished to kiss the Sultan's hand, he stabbed the Sultan with a sharp dagger."Oruc, Tevarih I Al-i Osman, as cited by Emmert.
Since about the late 15th century, Greek sources also begin to record the event. The Athenian scholar Laonicus Chalcocondyles (d. c. 1490) claims to draw on Greek traditions when he refers to Murad's killer as Miloes, "a man of noble birth [... who] voluntarily decided to accomplish the heroic act of assassination. He requested what he needed from Prince Lazar, and then rode off to Murad's camp with the intention of presenting himself as a deserter. Murad, who was standing in the midst of his troops before the battle, was eager to receive the deserter. Miloes reached the Sultan and his bodyguards, turned his spear against Murad, and killed him." Writing in the second half of the same century, Michael Doukas regarded the story as worthy of inclusion in his Historia Byzantina. He relates how the young nobleman pretended to desert the battle, was captured by the Turks and professing to know the key to victory, managed to gain access to Murad and kill him.
In 1976, Miodrag Popović suggested that the narrative elements of secrecy and stratagem in the Serbian tradition were all introduced from Turkish sources, seeking to defame the capabilities of their Christian opponents by attributing the death of the Murat to "devious" methods. Thomas A. Emmert agrees with him.
Emmert says that Turkish sources mentioned the assassination several times, while Western and Serbian sources didn't mention it until much later. He thinks that Serbians knew about the assassination, but decided not to mention it in their first accounts for unknown reasons. "It is important to note that neither this chronicle nor any of the other early Serbian accounts of the battle attributes Murad's death to the hand of an assassin (...) The theme of assassination, which appeared in the contemporary accounts of the battle from Florence and Siena and was also an important theme in all of the fifteenth century Turkish sources for the battle, would eventually become a central element in the Serbian epic. (...) It is surprising that the assassination of Murad is not recorded in any of the Serbian cult sources for the battle. Why the Serbian authors would fail to speak of the assassin if they knew of him is unclear, (...). Whatever the reason for this silence, it appears from later sources that the story of Murad's assassination was clearly known in Lazar's principality. "
In 1512, Ottoman historian Mehmed Nesri wrote a detailed account of the battle that became the source for later Ottoman and Western descriptions of the battle. Nesri's account took several elements from popular Serbian tradition, and described the assassination in a way which reflected negatively on the perpetrators.
There is no evidence about the knight's origin; theories that the legend was based on a Serb, Albanian or Hungarian knight have been put forward.
