Lacapins or Lekapeni - the Armenian  dynasty in Byzantium, first advanced in the person of Theophylact Avastakt , who saved the life of Emperor Vasily I in battle with the Saracens.
The name of the genus comes from the geographical area of Lacapa , located near Melitena . The founder of the dynasty was Feofilakt Avastakt, who saved the life of Emperor Vasily I of Macedonian. He is usually considered a peasant, but according to J. L. van Dieten, he belonged to the nobility  . His son reached the imperial throne under the name of Roman I. His daughter Elena was married off to Emperor Constantine VII , the son of Theophylact, at the age of sixteen, was appointed Patriarch of Constantinople , and his granddaughter Maria married off to Tsar Peter of Bulgaria . The overthrow of the aged Roman by sons ( 944 ) led to the departure of the clan from the political scene, with the exception of Theophylact (who remained the patriarch until 956 ) and the bastard son of the eunuch Vasily .
