John III Doukas Vatatzes
In his sixteenth year he was sent by his father, the logothete Constantine Akropolites the elder, to the court of John III Doukas Vatatzes, emperor of Nicaea, where Akropolites continued his studies under Theodore Hexapterygos and Nicephorus Blemmydes. The emperor afterwards entrusted George with important state missions, as did his successors (Theodore II Laskaris and Michael VIII Palaiologos). The office of Grand Logothete, or chancellor, was bestowed upon him in 1244.
