A participant in the Greek struggle for independence alongside Lord Byron, the philhellene George Finlay (1799-1875) lent his support to the newly liberated nation while diligently studying its past. The monographs he published in his lifetime covered the history of Greece since the Roman conquest, spanning two millennia. His two-volume History of the Greek Revolution (1861) is reissued separately in this series. Edited by the scholar Henry Fanshawe Tozer (1829-1916) and published in 1877, this seven-volume collection brought together Finlay's histories, incorporating significant revisions. Notably, Finlay gives due consideration to social and economic factors as well as high politics. Volume 4 covers medieval Greece and the empire of Trebizond. Opening with an overview of populations in Greece following the decline of Rome, Finlay traces the aftermath of the 1204 sack of Constantinople by the Fourth Crusade, up until the 1461 fall of the empire of Trebizond in Anatolia.
