Kliuchevskii's essay, “Dva vospitaniia” is the pioneering work in the history of childhood and of the family in Russia, and it has been sorely neglected. V.O. Kliuchevskii wrote this piece as a public lecture which was given on February 1, 1893, for the Moscow Committee on Literacy. In it he contrasts the educational values of traditional Muscovite society of the sixteenth century with those of Ivan Ivanovich Betskoi, Catherine the Great's principal educational advisor during the first years of her reign. More precisely, he compares two documents. The first was the Domostroi, the “House-orderer,” of the priest Sil'vestr. He, Metropolitan Makarii, and Aleksei Adashev were the principal advisors of Tsar Ivan IV in the early years of his active reign after 1547. They were the creators of the new ideology of the Muscovite state based on the dream of unified Orthodox Tsardom. They compiled a single all-Russian paterikon, a new unified law code, a unified ecclesiastical rule, and an official geneological history of Russia's rulers. The regimentation of personal behavior represented by the Domostroi was an essential part of the campaign for standardization and codification, which saw the origins of printing in Russia as well. In the sixteenth century these precepts had the same official sanction and status as did Catherine's legislation two hundred years later, especially the Statute of her boarding schools.
