cardinal in pectore from 1426, an appointment made public in 1430. In 1431 he was made president of the Council of Basle. He solemnly inaugurated it on 14 Dec. 1431 and continued his leadership even when it had been dissolved by Eugenius IV, though seeking to reconcile Pope and Council. After the transfer of the Council to Florence he took a prominent part in the negotiations for union between the Greek and Roman Churches. He persuaded the king of Hungary to renew war against the Turks; the Christians were totally defeated at Varna, Cesarini being killed, according to some sources, in flight after the battle.
