Mykhailo Hrushevsky's History of Ukraine-Rus, ' Volume 8: The Cossack Age, 1626-1650 deals with the period when the Cossacks' emergence as a political power and the Khmelnytsky Uprising made Ukraine a focal point in European and Near Eastern affairs. Based on an exhaustive examination of the sources and scholarly literature, Hrushevsky's volume 8 stands as the most comprehensive account of this dramatic period in Ukrainian history. Ukraine's central role in the international politics of the time makes the volume important to specialists and students of East European, Central European, Ottoman, Russian, and Jewish history, as well as to those studying revolution and state building in early modern Europe. For her work in translating volume 8 Marta Daria Olynyk was awarded the 2004 AAUS Translation Prize. This volume was translated by Marta Daria Olynyk and edited by Frank E. Sysyn (editor in chief) with the assistance of Myroslav Yurkevich.
