Abstract: The subject of this research is the evolution of the institutional structure, social base, ideology, trends and priorities of the activity of public organizations of the Russian diaspora in the United State at the turn of the XX – XXI centuries. Focus of attention is the cultural-educational societies, publishers, humanitarian foundations of the Russian America that has established relationships with Russia during the post-Soviet period, as well as the new public organizations formed within the Russian-speaking communities of New York, San Francisco, Houston, and other US cities in the late 1990’s – early 2000’s. The research methodology is based on the fundamental principles of historical science – historicism, scientific validity, and objectivity. The author also applies the systemic and contextual analysis, comparative and other special methods of historical research. The scientific novelty lies in determination of development trends of public organizations of Russian diaspora in the United States over the period from 1991 to the early 2000’s. The study demonstrates that in the context of conducting democratic reforms in Russia, the ideological component in the life of Russian America recedes into the background. The priority vectors of public activity of the Russian-American intelligentsia becomes the cultural dialogue with Russia, implementation of humanitarian and educational projects in the historical motherland. In the late 1990’s – early 2000’s, within the framework of Russian-speaking communities in the United States, appears a number of new social centers aimed at the promotion of the Russian language and culture in the United States, which activity reflected the socio-mental image of Russian Americans of the early XXI century, their interest in the dialogue with Russia and international world of the Russian compatriots.
