Akropolites' historical work, the Annals, embraces the period from the capture of Constantinople during the Fourth Crusade by the Latins in 1204 to its recovery by Michael Palaiologos in 1261, thus forming a continuation of the work of Nicetas Choniates.
Akropolites is considered a trustworthy authority as far as the statement of facts is concerned, and he is easy to understand, although he exhibits special carelessness in the construction of his sentences.
