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.
Southern Ukraine
Noticeable cultural differences in the region (compared with the rest of Ukraine, except Eastern Ukraine) are more "positive views" of the Russian language and of Joseph Stalin and more "negative views" of Ukrainian nationalism. In the 1991 Ukrainian independence referendum, a lower percentage of the total electorate voted for independence in Eastern and Southern Ukraine than in the rest of the country.
In a poll conducted by Kyiv International Institute of Sociology in the first half of February 2014, 19.4% of those polled in Southern Ukraine believed "Ukraine and Russia must unite into a single state"; nationwide this percentage was 12.5.
