Kaloyan, also known as Kalojan, Johannitsa or Ioannitsa (Bulgarian: Калоян; c. 1170–October 1207) was emperor (or tsar) of Bulgaria from 1196 to 1207. He was a younger brother of Theodor and Asen who lead the uprising of the Bulgarians and Vlachs in 1185. The uprising ended with the restoration of the independence of Bulgaria. He spent years as a hostage in Constantinople in the late 1180s. Theodor (who had been crowned emperor under the name Peter) made him his co-ruler after Asen was murdered in 1196. A year later, Theodor-Peter was also assassinated, and Kaloyan became the sole ruler of Bulgaria.

To obtain an imperial crown from the Holy See, Kaloyan entered into correspondence with Pope Innocent III, offering to acknowledge papal primacy. His expansionist policy brought him into conflict with the Byzantine Empire, Serbia and Hungary. Emeric, King of Hungary allowed the papal legate who delivered a royal crown to Kaloyan to enter Bulgaria only at the pope's demand. The legate crowned Kaloyan "King of the Bulgarians and Vlachs" on 8 November 1204, but he continued to regard his realm as an empire.

Kaloyan took advantage of the disintegration of the Byzantine Empire after the fall of Constantinople to the crusaders (or "Latins"). He captured fortresses in Macedonia and Thrace and supported the local population's riots against the crusaders. He defeated Baldwin I, Latin emperor of Constantinople, in the Battle of Adrianople on 14 April 1205. Baldwin was captured and died in Kaloyan's prison. He launched new campaigns against the crusaders and captured or destroyed dozens of their fortresses. He was thereafter known as Kaloyan the Romanslayer, because his troops murdered or captured thousands of Romaioi (or local Greeks). He died under mysterious circumstances during the siege of Thessalonica in 1207.

Early life[edit]

Kaloyan was the younger brother of Theodor and Asen who stirred up the uprising of the Bulgarians and Vlachs against the Byzantine Empire in 1185.[1] Theodor was crowned emperor and adopted the name Peter in 1185.[2] Asen became Peter's co-ruler before 1190.[3] They secured the independence of their realm with the assistance of the Cuman warriors from the Pontic steppes.[4]

He was born around 1170, according to Alexandru Madgearu, because he was still a teenager in 1188.[5] He was baptised Ivan (or John).[6] He was called Johannitsa ("Little Ivan") because Ivan was also the baptismal name of Asen.[6] Kaloyan derrived from the Greek expression for John the Handsome (Kallos Ioannis).[7] His Greek enemies also called him Skyloioannes ("John the Dog"), which gave rise to references to Tsar Skaloyan or Scaluian in frescos in the Dragalevtsi Monastery and the Sucevița Monastery.[8]

After the Byzantines captured Asen's wife, Kaloyan was sent as a hostage to Constantinople to replace her in the spring of 1188.[9][10] The date of his release is not known.[10] He was again in his homeland when a boyar, Ivanko, murdered Asen in Tarnovo in 1196.[10] Ivanko tried to secure his rule with Byzantine support, but Theodor-Peter forced him to flee to the Byzantine Empire.[11]

Reign[edit]

Conflicts with the Byzantine Empire[edit]

The Byzantine historian, Niketas Choniates, mentioned that Theodor-Peter designated Kaloyan "to assist him in his labors and share in his rule"[12] at an unspecified time.[11] Kaloyan became the sole ruler of Bulgaria after Theodor-Peter was murdered in 1197.[13][14] He soon broke into Thrace and launched frequent raids against the province during the following months.[15] Around the same time, he sent a letter to Pope Innocent III, urging him to dispatch an envoy to Bulgaria.[13][16] He wanted to persuade the pope to acknowledge his rule in Bulgaria.[13] Innocent eagerly entered into correspondence with Kaloyan because the reunification of the Christian denominations under his authority was one of his principal purposes.[17]

The Byzantine Emperor Alexios III Angelos made Ivanko the commander of Philippopolis (now Plovdiv in Bulgaria).[14][15] Ivanko seized two fortresses in the Rhodopi Mountains, but he made an alliance with Kaloyan already in 1198.[15] Cumans and Vlachs from the lands to the north of the river Danube broke into the Byzantine Empire in the spring and autumn of 1199.[18] Choniates, who recorded these events, did not mention that Kaloyan cooperated with the invaders, who most probably crossed Bulgaria without his authorization.[19] He captured Braničevo, Velbuzhd (now Kyustendil in Bulgaria), Skopje and Prizren from the Byzantines most probably in that year, according to historian Alexandru Madgearu.[20]

Innocent III's envoy came to Bulgaria in late December 1199, taking a letter from the pope to Kaloyan.[21] Innocent stated that he was informed that Kaloyan's forefathers had come "from the City of Rome".[21] Kaloyan's answer, written in Old Church Slavonic, was not preserved, but its content can be reconstructed based on his later correspondence with the Holy See.[22] Kaloyan styled himself "Emperor of the Bulgarians and Vlachs", also asserting that he was the legitimate successor of the rulers of the First Bulgarian Empire.[22][23] He demanded an imperial crown from the pope and expressed his wish to put the Church of his realm under the pope's jurisdiction.[23]

The Byzantines captured Ivanko and occupied his land in 1200.[24] Kaloyan launched a new campaign against Byzantine territories in March 1201.[19] He destroyed Constantia (now Simeonovgrad in Bulgaria) and captured Varna.[25][23] He also supported the rebellion of Dobromir Chrysos and Manuel Kamytzes against Alexios III, but they both were defeated.[23][26] Roman Mstislavich, prince of Halych and Volhynia, invaded the Cumans' territories, forcing them to return to their homeland in 1201.[27] After his allies' defeat, Kaloyan concluded a peace treaty with Alexios III and withdrew his troops from Thrace in late 1201 or in 1202.[23][28] According to Kaloyan's letter to the pope, Alexios III was also willing to send an imperial crown to him and to acknowledge the autocaphalous (or autonomous) status of the Bulgarian Church.[23]

Imperial ambitions[edit]

Vukan Nemanjić, ruler of Zeta, expelled his brother, Stefan, from Serbia in 1202.[29] Kalojan gave shelter to Stefan and enabled the Cumans to invade Serbia across Bulgaria.[30] He invaded Serbia and captured Niš in the summer of 1203.[31] He most probably also seized Dobromir Chrysos's realm, with its capital at Prosek, according to Madgearu.[32] Emeric, King of Hungary, who claimed Belgrade, Braničevo and Niš, intervened in the conflict on Vukan's behalf.[30] The Hungarian army occupied territories which were also claimed by Kaloyan.[33] Since Vukan had already acknowledged papal primacy, Innocent III urged Kaloyan to make peace with him in September.[34] In the same month, the papal legate, John of Casamari, gave a pallium to Basil I, the head of the Bulgarian Church, confirming his rank of archbishop, but denying his elevation to the rank of patriarch.[35]

Pope Innocent III's letter to Kaloyan

Dissatisfied with the pope's act, Kaloyan sent a new letter to Rome, asking Innocent to send cardinals who could crown him emperor.[36][37] He also informed the pope that Emeric of Hungary had seized five Bulgarian bishoprics, asking Innocent to arbitrate in the dispute and determine the boundary between Bulgaria and Hungary.[37] In the letter, he styled himself the "Emperor of the Bulgarians".[36] The pope did not accept Kaloyan's claim to an imperial crown, but dispatched Cardinal Leo Brancaleoni to Bulgaria in early 1204 to crown him king.[38][39]

Kaloyan sent envoys to the crusaders who were besieging Constantinople, offering military support to them if "they would crown him king so that he would be lord of his land of Vlachia", according to Robert of Clari's chronicle.[36][40] However, the crusaders treated him with disdain and did not accept his offer.[40] The crusaders captured Constantinople on 13 April.[41] They elected Baldwin IX of Flanders emperor and decided to divide the Byzantine Empire among themselves.[42]

The papal legate, Brancaleoni, travelled through Hungary, but he was arrested at Keve (now Kovin in Serbia) on the Hungarian–Bulgarian frontier.[43] Emeric of Hungary urged the cardinal to summon Kaloyan to Hungary and to arbitrate in their conflict.[43] Brancaleoni was only released at the pope's demand in late September or early October.[39][44] He consecrated Basil primate of the Church of the Bulgarians and Vlachs on 7 November.[45] Next day, Brancaleone crowned Kaloyan king.[44] In his subsequent letter to the pope, Kaloyan styled himself as "King of Bulgaria and Vlachia", but referred to his realm as an empire and to Basil as a patriarch.[44][45]

War with the crusaders[edit]

Taking advantage of the disintegration of the Byzantine Empire, Kaloyan captured former Byzantine territories in Thrace.[46] Initially, he attempted to secure a peaceful division of the lands with the crusaders (or Latins).[46] He asked Innocent III to prevent them from attacking Bulgaria.[47] However, the crusaders wanted to implement their treaty about the division of the Byzantine territories, including lands that Kaloyan also claimed.[40]

Kaloyan gave shelter to Byzantine refugees and perusaded them to stir up riots in Thrace and Macedonia against the Latins.[48] The refugees, according to Robert of Clari's account, also pledged that they would elect him emperor if he invaded the Latin Empire.[48] The Greek burghers of Adrianople (now Edirne in Turkey) and the nearby towns rose up against the Latins in early 1205.[48] Kaloyan promised that he would send them reinforcements before Easter.[49] Considering Kaloyan's cooperation with the rebels as a dangerous alliance, Emperor Baldwin decided to launch a counter-attack and ordered the withdrawal his troops from Asia Minor.[46] He laid siege to Adrianople before he could muster all his troops.[46] Kaloyan hurried to the town at the head of an army of more than 14,000 Bulgarian, Vlach and Cuman warriors.[50] A feigned reatreat of the Cumans drew the heavy cavalry of the crusaders into an ambush in the marshes north of Adrianople, enabling Kaloyan to inflict a crushing defeat on them on 14 April 1205.[46][51]

Bulgaria under Kaloyan (1197–1207)

Baldwin who was captured in the battlefield died in captivity in Tarnovo.[52] Choniates accused Kaloyan of having tortured and murdered Baldwin because he "seethed with anger"[53] against the crusaders.[46][54] George Akropolites added that Baldwin's head was "cleaned of all its contents and decorated all round with ornaments"[55] to be used as a goblet by Kaloyan.[46][54] On the other hand, Baldwin's brother and successor, Henry, informed the pope that Kaloyan behaved respectfully towards the crusaders who had been captured at Adrianople.[56]

Kaloyan's troops pillaged Thrace and Macedonia after his victory over the Latins.[57] He launched a campaign against the Kingdom of Thessalonica and laid siege to Serres in late May.[58] He promised free passage to the defenders, but after their surrender, he broke his word and had them captured.[59] He continued the campaign and seized Veria and Moglena (now Almopia in Greece).[32] Most inhabitants of Veria were murdered or captured at his order.[32] Henry (who still ruled the Latin Empire as regent) launched a counter-invasion against Bulgaria in June.[60][61] He could not capture Adrianople and a sudden flood forced him to also lift the siege of Didymoteicho.[60]

Kaloyan decided to take vengeance of the townspeople of Philippopolis who had voluntarily obeyed to the crusaders.[61] With the assistance of the local Paulicians, he seized the town and ordered the murder of the most prominent burghers.[62] The commoners were delivered in chains to "Vlachia".[61] He returned to Tarnovo after a riot had broken out against him in the second half of 1205 or early 1206.[63][64] He "subjected the rebels to harsh punishments and novel methods of execution",[65] according to Choniates.[64] He again invaded Thrace in January 1206.[66] He captured Rousion (now Keşan in Turkey) and massacred its Latin garrison.[66] Thereafter he destroyed most fortresses along the Via Egnatia as far as Athira (present-day Büyükçekmece in Turkey).[66] The local inhabitants were captured and taken to the lands near the Lower Danube.[66] Akropolites recorded that thereafter Kaloyan called himself "Romanslayer", with a clear reference to Basil II who had been known as the "Bulgarslayer" after his destruction of the First Bulgarian Empire.[67][68]

The massacre and capture of their compatriots outraged the Greeks in Thrace and Macedonia.[63][69] They realized that Kaloyan was more hostile to them than the Latins.[70] The burghers Adrianople and Didymoteicho approached Henry, offering their voluntary submission.[63] Henry accepted the offer and assisted Theodore Branas to take possession of the two towns.[63] Kaloyan attacked Didymoteicho in June, but the crusaders forced him to lift the siege.[71] Soon after Henry was crowned emperor on 20 August, Kaloyan returned and destroyed Didymoteicho.[72] He soon laid siege to Adrianople, but Henry compelled him to withdraw his troops from Thrace.[73] Henry also broke into Bulgaria and released 20,000 prisoners in October.[74] Boniface, King of Thessalonica, had meanwhile recaptured Serres.[75]

Kaloyan concluded an alliance with Theodore I Laskaris, Emperor of Nicaea.[75][76] Laskaris had started a war against David Komnenos, Emperor of Trebizond, who was supported by the Latins.[76] He persuaded Kaloyan to invade Thrace, forcing Henry to withdraw his troops from Asia Minor.[76] Kaloyan laid siege to Adrianople in April 1207, using trebuchets, but the defenders resisted.[74] A month later, the Cumans abandoned Kaloyan's camp, because they wanted to return to the Pontic steppes, thus Kaloyan had to lift the siege.[75][72] Innocent III urged Kaloyan to make peace with the Latins, but he did not obey.[77]

Henry concluded a truce with Laskaris in July 1207.[75][77] He also had a meeting with Boniface of Thessalonica who acknowledged his suzerainty at Kypsela in Thrace.[75][77] However, on his way back to Thessalonica, Boniface was ambushed and killed at Mosynopolis on 4 September.[77] According to Geoffrey of Villehardouin, local Bulgarians were the perpetrators who sent Boniface's head to Kaloyan.[77] Robert of Clari and Choniates recorded that Kaloyan had set up the ambush.[78] Boniface was succeeded by his minor son, Demetrius.[79] The child king's mother, Margaret of Hungary, took up the administration of the kingdom.[79] Kaloyan hurried to Thessalonica and laid siege to the town.[78]

Death[edit]

Kaloyan's supposed grave in the Church of the Holy Forty Martyrs in Tarnovo

Kaloyan died during the siege of Thessalonica in October 1207, but the circumstances of his death are uncertain.[80] Akropolites stated that he died of pleurisy.[81][82] However, he also recorded a rumour claiming that Kaloyan's "death was caused by divine wrath; for it seemed to him that an armed man appeared before him in his sleep and struck his side with a spear".[82][83]

Legends about Saint Demetrius of Thessaloniki's intervention on behalf of the besieged town were actually recorded shortly after Kaloyan's death.[81][84] Robert of Clari wrote already before 1216 that the saint himself came to Kaloyan's tent and "struck him with a lance through the body",[85] causing his death.[84] Stefan Nemanjić wrote down the same legend in 1216 in his hagiography about his father, Stefan Nemanja.[84] John Staurakios, who compiled the legends of Saint Demetrius in the late 13th century, recorded that a man riding on a white horse struck Kaloyan with a lance.[86] Kaloyan, continued Staurakios, associated the attacker with Manastras, the commander of his mercenaries, who thus had to flee before Kaloyan's death.[87] The legend was depicted on the walls of more than five Orthodox churches and monasteries.[8] For instance, a fresco in the Decani Monastery depicts Saint Demetrius slaying Tsar Skaloyan.[82]

The contradictory records of Kaloyan's death gave rise to multiple scholarly theories, many of them accepting that he was murdered.[81][64] Madgearu says, Kaloyan was actually murdered by Manastras, who had most probably been hired by Kaloyan's wife and nephew, Boril.[64] Historians Genoveva Cankova-Petkova and Francesco Dall'Aglia also write, Manastras killed Kaloyan, but they assume that the Greeks had persuaded him to turn against the tsar.[64]

The location of Kaloyan's grave is unknown.[88] According to the late 13th-century version of Life of Saint Sava of Serbia, Kaloyan's body embalmed and delivered to Tarnovo.[89] However, the older version of the same legend, completed in 1254, does not mention this episode.[82] A golden ring, which was found in a grave near the Church of the Holy Forty Martyrs in Tarnovo in 1972, bears the Cyrillic inscription Kaloianov prăsten ("Kaloyan's ring").[90] Historian Ivan Dujčev stated that the ring proved that Kaloyan's remains were transferred to the church, which was built in 1230.[90] Based on the skull found in the same grave and associated with Kaloyan, anthropologist Jordan Jordanov reconstructed Kaloyan's face.[90] The identification of the grave as Kaloyan's burial place is controversial, because the ring bearing his name cannot be dated before the 14th century.[90] Furthermore, the graves of all other royals who were buried in the same place are located within the church, suggesting that the ring was not owned by Kaloyan, but by one of his 14th-century namesakes.[88]

Family[edit]

Kaloyan's wife was a Cuman princess.[13] According to a gossip recorded by Alberic of Trois-Fontaines, she tried to seduce the Latin Emperor Baldwin who had been imprisoned in Tarnovo.[54] However, the gossip continued, Baldwin refused her, for which she accused him of having tried to seduce her; outraged by his wife, Kaloyan had Baldwin executed and fed his corpse to the dogs.[54] Based on the story of Potiphar and his wife, the rumour is obviously unreliable, according to Madgearu.[54] After Kaloyan's death, his widow married his successor, Boril.[91] Boril gave the daughter of Kaloyan and his wife in marriage to the Latin Emperor Henry in 1211.[92] Her name is unknown.[93]
