Stephen Lekapenos, co-emperor of the Byzantine Empire

Stephen Lekapenos or Lecapenus was the second son of the Byzantine emperor Romanos I Lekapenos, and co-emperor from 924 to 945. With his younger brother Constantine, he deposed Romanos I in December 944, but they were overthrown and exiled a few weeks later by their brother in law, the legitimate emperor Constantine VII. Stephen lived out his life in exile on the island of Lesbos, where he died on Easter 963.

The Byzantine Empire, also known as the Eastern Roman Empire, was the continuation of the Roman Empire centred on Constantinople during late antiquity and the Middle Ages. Having survived the events that caused the fall of the Western Roman Empire in the 5th century AD, it endured until the fall of Constantinople to the Ottoman Empire in 1453. The term 'Byzantine Empire' was coined only after its demise; its citizens used the term 'Roman Empire' and called themselves 'Romans'.
