John VIII Palaiologos

   Emperor (q.v.) from 1425-1448, succeeding his father Manuel II (q.v.). His reign saw continued Ottoman (q.v.) advances against Byzantine European possessions. Thessalonike (q.v.) fell in 1430, and before his reign ended the Despotate of Morea (q.v.) began paying tribute to Murad II (q.v.). John's attempt to secure aid from the West required the union of the churches at the council of Ferrara-Florence (qq.v.) in 1438-1439. In response, Pope Eugenius IV (q.v.) preached a Crusade that was crushed by the Ottomans at Varna (q.v.) in 1444. Thus, the West found itself incapable of saving Byzantium (q.v.) while in Constantinople (q.v.) John VIII found himself unable to make church union anything more than a union on paper.
