Stephen Lekapenos, co-emperor of the Byzantine Empire
Stephen Lekapenos or Lecapenus (Greek: Στέφανος Λεκαπηνός, Stéphanos Lekapenós; died 18 April 963) was the second son of the Byzantine emperor Romanos I Lekapenos (r. 920–944), and co-emperor from 924 to 945. With his younger brother Constantine, he deposed Romanos I in December 944, but was overthrown and exiled by the legitimate emperor Constantine VII (r. 913–959) a few weeks later. Stephen lived out his life in exile on the island of Lesbos, where he died on Easter 963.
