History of Ukraine
Strikingly different interpretations of the medieval state of Kievan Rus' appear in the four schools of historiography within Ukraine: Russophile, Sovietophile, Eastern Slavic, and Ukrainophile. The Sovietophile and Russophile schools have become marginalized in independent Ukraine, with the Ukrainophile school being dominant in the early 21st century. The Ukrainophile school promotes an identity that is mutually exclusive of Russia. It has come to dominate the nation's educational system, security forces, and national symbols and monuments, although it has been dismissed as nationalist by Western historians. The East Slavic school, an eclectic compromise between Ukrainophiles and Russophilism, has a weaker ideological and symbolic base, although it is preferred by Ukraine's centrist former elites.
Western Ukraine
Noticeable cultural differences in the region (compared with the rest of Ukraine especially Southern Ukraine and Eastern Ukraine) are more "negative views" on the Russian language and on Joseph Stalin and more "positive views" on Ukrainian nationalism. Calculating the "yes"-votes as a percentage of the total electorate reveals that a higher percentage of all (possible) voters in Western Ukraine supported Ukrainian independence in the 1991 Ukrainian independence referendum than in the rest of the country.
In a poll conducted by Kyiv International Institute of Sociology in the first half of February 2014 0.7% of polled in West Ukraine believed "Ukraine and Russia must unite into a single state", nationwide this percentage was 12.5.
