The paper concerns three conceptions of Russian 19th century thinkers - Nikolai Danilevsky, Konstantin Leontiev and Vladimir Soloviev - with common vision, that Russia should be united with other countries to step to higher level of its development. The visions are different, Danilevsky's plan of panslavic federation bears the patterns of utopia, Leontiev's image of Eastern Union is an attempt of own solving of Easter Question and Soloviev's theocracy is an example of the most radical utopia in Russian mind of the time.
