John VI Kantakouzenos or Cantacuzene^[1] (Greek: Ἰωάννης Ἄγγελος Παλαιολόγος Καντακουζηνός, Iōánnēs Ángelos Palaiológos Kantakouzēnós;^[2] Latin: Iohannes Cantacuzenus;^[3] c. 1292 – 15 June 1383^[4]) was a Byzantine Greek nobleman, statesman, and general. He served as grand domestic under Andronikos III Palaiologos and regent for John V Palaiologos before reigning as Byzantine emperor in his own right from 1347 to 1354. Deposed by his former ward, he was forced to retire to a monastery under the name Joasaph Christodoulos (Greek: Ἰωάσαφ Χριστόδουλος) and spent the remainder of his life as a monk and historian. At age 90 or 91 at his death, he was the longest-lived of the Roman emperors.
