Origins & Early Life

The Treaty of 815 (Bulgarian: Договор от 815) was a 30-year peace agreement signed in Constantinople between the Bulgarian Khan Omurtag and the Byzantine Emperor Leo V the Armenian. With the succession of Khan Krum on the Bulgarian throne in 803 began the last and decisive part of the prolonged succession of Byzantine–Bulgarian conflicts which started in 756. For a little over a decade until his death in 814, Krum achieved significant successes over the Byzantine Empire, seizing the important city of Serdica in 809 and decisively defeating the Byzantine armies at the Varbitsa pass and at Versinikia.

Career & Major Achievements

His son and successor Omurtag tried to continue Krum's aggressive policy but his campaign in 814 was stopped by the Byzantines. As both countries were exhausted by the sustained military effort, peace negotiations began.

Enduring Legacy & Impact

In the beginning of 815 Omurtag sent emissaries to Constantinople to negotiate the peace. The signing ceremony was a solemn event and performed in the presence of numerous people.
