" The change in the geopolitical aims of the Kyivan princes, from Yaroslav the Wise to Andrei Bogoliubsky, reflects the reduction of their political loyalties from the entire realm of Kyivan Rus’ to a number of principalities defined by the term “Rus’ Land” and eventually to peripheral principalities that grew strong enough to rival Kyiv in the twelfth and early thirteenth centuries. Historians look to those principality-based identities for the origins of the modern East Slavic nations. The Vladimir-Suzdal principality served as a forerunner of early modern Muscovy and, eventually, of modern Russia. Belarusian historians look to the Polatsk principality for their roots. And Ukrainian historians study the principality of Galicia-Volhynia to uncover the foundations of Ukrainian nation-building projects. But all those identities ultimately lead back to Kyiv, which gives Ukrainians a singular advantage: they can search for their origins without ever leaving their capital. "
