BIOGRAPHICAL DOSSIER

Life and historical role

01

Life and political setting

Kaloyan was the brother of Peter and Asen, leaders of the 1185 revolt against Byzantium that founded the Second Bulgarian Empire, and took the throne in 1197. Corresponding with Pope Innocent III, he accepted church union and in 1204 received a royal crown from a papal legate.

02

Role in the Crusades

After the Latin Empire was founded, Kaloyan's offer of alliance with the Latins was rejected. When the Greek nobles of Thrace rose against the Latins, Kaloyan supported them. On 14 April 1205, before Adrianople, Bulgarian and Cuman cavalry trapped the Latin army; Emperor Baldwin was captured and Louis of Blois killed.

03

Historical significance and source problems

The victory at Adrianople halted the Latin Empire's expansion in the Balkans. Kaloyan, who also treated the Greek population harshly, earned the nickname “Romaioktonos” (Roman-slayer) and died in 1207 during the siege of Thessalonica. Villehardouin, Niketas Choniates and papal correspondence are the main sources.
