 The Crusaders's capture of Constantinople in 1204 during the Fourth Crusade ended all support for higher education, although the government in exile in Nicaea gave some support to individual private teachers.After the restoration in 1261 attempts were made to restore the old system, but it never fully recovered and most teaching fell to private teachers and professions.Some of these private teachers included the diplomat and monk Maximos Planudes (1260–1310), the historian Nikephoros Gregoras (1291–1360), and the man of letters Manuel Chrysoloras, who taught in Florence and influenced the early Italian humanists on Greek studies.
