Origins of the conflict
Around 1221–1222 Emperor Ivan Asen II of Bulgaria made an alliance with Theodore Komnenos Doukas, the ruler of Epirus. Secured by the treaty, Theodore managed to conquer Thessalonica from theThe battle
Theodore Komnenos summoned a large army, including western mercenaries. He was so confident of victory that he took the whole royal court with him, including his wife and children. His army moved slowly and plundered the villages on its way. When the Bulgarian tsar learned that the state was invaded, he gathered a small army of a few thousand men (including Cumans, that Acropolites describes as Scyths) and quickly marched southwards. In four days the Bulgarians covered a distance three times longer than Theodore's army had travelled in a week. On 9 March, the two armies met near the village of Klokotnitsa. It is said that Ivan Asen II ordered the broken mutual protection treaty to be stuck on his spear and used as a flag. He was a good tactician and managed to surround the enemy, who were surprised to meet the Bulgarians so soon. The battle continued until sunset. Theodore's men were completely defeated, only a small force under his brother Manuel managed to escape from the battlefield. The rest were killed in the battle or captured, including the royal court of Thessalonica and Theodore himself.Ivan Asen II's Tarnovo Inscription
In order to commemorate the battle, the Bulgarian emperor had an inscription carved in one of the marble columns of the Church "Holy Forty Martyrs" in the capital of the Bulgarian empire Veliko Tarnovo. Among all existing documents the text of this inscription is the most accurate evidence of the outcome and the aftermath of the battle: ''"In the Year of the World 6738 (1230), third indiction. John Asen in Christ God true Tsar and sovereign of the Bulgarians, son of the old Tsar Asen, raised from the foundations and decorated with art this holy church in the name of the Holy 40 Martyrs, with the help of whom in the twelfth year of my reign when this temple was being decorated. I went to war in Romania and defeated the Greek army and captured their Tsar, Kyr Teodore Komnenos, together with all his boyars. And I conquered all of his land from Odrin ( Adrianople) to Drach ( Dyrrhachium), Greek and also Albanian and Serbian; and the towns around Tsarigrad and this very town were ruled by the Frazi (Latins), but they also were subjugated to my empire; because they had no other Tsar but me and thanks to me they spent their days, because God ordered this, because without Him neither a deed, nor a word is done. Glory to Him forever, Amen."''Turnovo inscription of Tsar Ivan Asen II in the Holy 40 Martyrs Church in honour of the victory at Klokotnitsa on 9 March 1230Aftermath
Ivan Asen II immediately released the captured soldiers without any conditions and the nobles were taken to Tarnovo. His fame for being a merciful and just ruler went ahead of his march to the lands of Theodore Komnenos and Theodore's recently conquered territories in Thrace and Macedonia were regained by Bulgaria without resistance. Thessalonica itself became a Bulgarian vassal under Theodore's brother Manuel. However, after the passing of Ivan Asen II, the vassalage of Epirus to the Bulgarian Empire ceased and Bulgaria passed into a rapid political decline, meanwhile the Despotate of Epirus grew once more under the leadership Michael II of Epirus who reconquered many lands from the decayed Tsardom.Notes
