(重定向自Tervel)



Khan Tervel (Bulgarian:Тервел) also called Tarvel, or Terval, or Terbelis in some Byzantine sources, was the Emperor of Bulgaria during the First Bulgarian Empire at the beginning of the 8th century. In 705 Emperor Justinian II named him Caesar, the first foreigner to receive this title. He was probably a Christian like his grandfather Khan Kubrat. Tervel played an important role in defeating the Arabs during the Siege of Constantinople in 717–718.
