In June 1422, John VIII Palaiologos had supervised the defense of Constantinople during a siege by Sultan Murad II, but had to accept the loss of Thessalonica to the Ottoman Turks in 1430. To secure protection against the Ottomans, he visited Pope Eugene IV and consented to the union of the Greek and Roman churches, which was ratified at the Council of Florence in 1439. He was accompanied by the Patriarch of Constantinople Joseph II, and by George Gemistos Plethon, a Neoplatonist philosopher who was very influential among the academics of Italy and influenced the nascent western European Renaissance. The proposed church union failed due to opposition by his own people, who refused to submit to the Pope, but by his prudent conduct towards the Ottoman Empire he succeeded in holding possession of Constantinople.
