The view of Ukrainians as constituents of the Russian nation goes back to the founding myth of modern Russia as a nation conceived and born in Kyiv, … - Serhii Plokhy

Both Ukrainians and Russians claim Yaroslav the Wise as one of their eminent medieval rulers, and his image appears on the banknotes of both countries. The Ukrainian bill depicts Yaroslav with a Ukrainian-style moustache in the tradition of Prince Sviatoslav and the Ukrainian Cossacks. On the Russian note, we see a monument to him as the legendary founder of the Russian city of Yaroslavl, first mentioned in a chronicle seventeen years after his death. The Russian bill shows Yaroslav with a beard in the tradition of Ivan the Terrible and the Muscovite tsars of his era.

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.

Since the fall of the USSR, the Russian nation-building project has switched its focus to the idea of forming a single Russian nation not divided into branches and unifying the Eastern Slavs on the basis of the Russian language and culture. Ukraine has become the first testing ground for this model outside the Russian Federation.
