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.
Ukraine
According to the constitution, the state language of Ukraine is Ukrainian. Russian is widely spoken, especially in eastern and southern Ukraine. According to the 2001 census, 67.5 percent of the population declared Ukrainian as their native language and 29.6 percent declared Russian. Most native Ukrainian speakers know Russian as a second language. Russian was the "de facto" official language of the Soviet Union but both Russian and Ukrainian were official languages in the Soviet Union and in the schools of the Ukrainian SSR learning Ukrainian was mandatory. Effective in August 2012, a new law on regional languages entitles any local language spoken by at least a 10 percent minority be declared official within that area. Russian was within weeks declared as a regional language in several southern and eastern oblasts (provinces) and cities. Russian can now be used in these cities'/oblasts' administrative office work and documents. On 23 February 2014, following the 2014 Ukrainian revolution, the Ukrainian Parliament voted to repeal the law on regional languages, making Ukrainian the sole state language at all levels; however, the repeal was not signed by acting President Turchynov and current President Poroshenko.
