Slavic language based on the Moscow dialect. Since then the trend of language policy in Russia has been standardization in both the restricted sense of reducing dialectical barriers between ethnic Russians, and the broader sense of expanding the use of Russian alongside or in favour of other languages that exist within the borders of the Russian Empire, and the later Soviet Union and recently, Russian Federation. The current standard form of Russian is generally regarded as the modern Russian literary language ( – "sovremenny russky literaturny yazyk"). It arose at the beginning of the 18th century with the modernization reforms of the Russian state under the rule of Peter the Great and developed from the Moscow (Middle or Central Russian) dialect substratum under the influence of some of the previous century's Russian chancery language. This occurred in spite of the fact that Saint Petersburg, the Western-oriented capital created by the "Westernizing" Tsar Peter the Great, was the capital of the Russian Empire for over 200 years. Mikhail Lomonosov compiled the first book of Russian grammar aimed at standardization in 1755. The Russian Academy's first explanatory Russian dictionary appeared in 1783. In the 18th and late 19th centuries, a period known as the "Golden Age" of Russian Literature, the grammar, vocabulary, and pronunciation of the Russian language in a standardized literary form emerged. Prior to the Bolshevik Revolution, the spoken form of the Russian language was that of the nobility and the urban bourgeoisie. Russian peasants, the great majority of the population, continued to speak in their own dialects. However, the peasants' speech was never systematically studied, as it was generally regarded by philologists as simply a source of folklore and an object of curiosity. This was acknowledged by the noted Russian dialectologist Nikolai Karinsky (1873–1935), who toward the end of his life wrote: “Scholars of Russian dialects mostly studied phonetics and morphology. Some scholars and collectors compiled local dictionaries. We have almost no studies of lexical material or the syntax of Russian dialects.” After 1917, Marxist linguists had no interest in the multiplicity of peasant dialects and regarded their language as a relic of the rapidly disappearing past that was not worthy of scholarly attention. Nakhimovsky quotes the Soviet academicians A.M Ivanov and L.P Yakubinsky, writing in 1930: The language of peasants has a motley diversity inherited from feudalism.
