From The Gates of Europe: A History of Ukraine, by Serhii Plokhy (Basic Books, 2017), Kindle pp. 24-27:
Nation is an important—although not dominant—category of analysis and element of the story that, along with the ever changing idea of Europe, defines the nature of this narrative. This book tells the history of Ukraine within the borders defined by the ethnographers and mapmakers of the late nineteenth and early twentieth centuries, which often (but not always) coincided with the borders of the present-day Ukrainian state. It follows the development of the ideas and identities linking those lands together from the times of the medieval Kyivan state, known in historiography as Kyivan Rus’, to the rise of modern nationalism and explains the origins of the modern Ukrainian state and political nation. In doing so, the book focuses on Ukrainians as the largest demographic group and, in time, the main force behind the creation of the modern nation and state. It pays attention to Ukraine’s minorities, especially Poles, Jews, and Russians, and treats the modern multiethnic and multicultural Ukrainian nation as a work in progress. Ukrainian culture always existed in a space shared with other cultures and early on involved navigating among the “others.” The ability of Ukrainian society to cross inner and outer frontiers and negotiate identities created by them constitutes the main characteristic of the history of Ukraine as presented in this book.
Politics, international and domestic, provide a convenient storyline, but in writing this book, I found geography, ecology, and culture most lasting and thus most influential in the long run. Contemporary Ukraine, as seen from the perspective of longue durée cultural trends, is a product of the interaction of two moving frontiers, one demarcated by the line between the Eurasian steppes and the eastern European parklands, the other defined by the border between Eastern and Western Christianity. The first frontier was also the one between sedentary and nomadic populations and, eventually, between Christianity and Islam. The second goes back to the division of the Roman Empire between Rome and Constantinople and marks differences in political culture between Europe’s east and west that still exist today. The movement of these frontiers over the centuries gave rise to a unique set of cultural features that formed the foundations of present-day Ukrainian identity.
One cannot tell the history of Ukraine without telling the story of its regions. The cultural and social space created by the movement of frontiers has not been homogenous. As state and imperial borders moved across the territory defined by Ukrainian ethnic boundaries, they created distinct cultural spaces that served as foundations of Ukraine’s regions—the former Hungarian-ruled Transcarpathia, historically Austrian Galicia, Polish-held Podolia and Volhynia, the Cossack Left Bank of the Dnieper with the lower reaches of that river, Sloboda Ukraine, and finally the Black Sea coast and the Donets basin, colonized in imperial Russian times. Unlike most of my predecessors, I try to avoid treating the history of various regions (such as the Russian- and Austrian-ruled parts of Ukraine) in separate sections of the book but rather look at them together, providing a comparative perspective on their development within a given period.
In conclusion, a few words about terminology. The ancestors of modern Ukrainians lived in dozens of premodern and modern principalities, kingdoms, and empires, and in the course of time they took on various names and identities. The two key terms that they used to define their land were “Rus’” and “Ukraine.” (In the Cyrillic alphabet, Rus’ is spelled Pycь: the last character is a soft sign indicating palatalized pronunciation of the preceding consonant.) The term “Rus’,” brought to the region by the Vikings in the ninth and tenth centuries, was adopted by the inhabitants of Kyivan Rus’, who took the Viking princes and warriors into their fold and Slavicized them. The ancestors of today’s Ukrainians, Russians, and Belarusians adopted the name “Rus’” in forms that varied from the Scandinavian/Slavic “Rus’” to the Hellenized “Rossiia.” In the eighteenth century, Muscovy adopted the latter form as the official name of its state and empire.
The Ukrainians had different appellations depending on the period and region in which they lived: Rusyns in Poland, Ruthenians in the Habsburg Empire, and Little Russians in the Russian Empire. In the course of the nineteenth century, Ukrainian nation builders decided to end the confusion by renouncing the name “Rus’” and clearly distinguishing themselves from the rest of the East Slavic world, especially from the Russians, by adopting “Ukraine” and “Ukrainian” to define their land and ethnic group, both in the Russian Empire and in Austria-Hungary. The name “Ukraine” had medieval origins and in the early modern era denoted the Cossack state in Dnieper Ukraine. In the collective mind of the nineteenth-century activists, the Cossacks, most of whom were of local origin, were the quintessential Ukrainians. To link the Rus’ past and the Ukrainian future, Mykhailo Hrushevsky called his ten-volume magnum opus History of Ukraine-Rus’. Indeed, anyone writing about the Ukrainian past today must use two or even more terms to define the ancestors of modern Ukrainians.
In this book, I use “Rus’” predominantly but not exclusively with reference to the medieval period. “Ruthenians” to denote Ukrainians of the early modern era, and “Ukrainians” when I write about modern times. Since the independent Ukrainian state’s creation in 1991, its citizens have all come to be known as “Ukrainians,” whatever their ethnic background. This usage reflects the current conventions of academic historiography, and although it makes for some complexity, I hope that it does not lead to confusion.
