The author seeks to enlarge the temporal, spatial and structural-evolutionary context, within which problems of conceptualization of Russian development prove to be accessible to solution. These efforts are to a large extent motivated by the author's dissatisfaction with the cognitive potential of the model of the "reforms-counter-reforms cycles" as applied to the study of evolutionary cycles of development. Proposed in the article is a different, partly alternative, partly additive model of politico-state development of Rus-Moskovia-Russia - a model describing this development as an evolutional sequence of the so-called "spurt" and "relaxation" cycles alternating in Russian history. "The durable 20th century" of the Russian history (according to the author's dating: 1881 - 2025) is conceptualized as a period of a concluding "spurt" within the change of the multi-centuries' paradigm of development.
