ИСТИНА

In Gumilev's theories, natural attributes are fundamental properties of ethnic group. At the same time, ethnic group is a kind of “closed and particle system”, whose internal system-level is significantly divided. Ethnic group has a fixed lifecycle——“Ethnogenesis”, which begins from the appearance of the ethnic group and ends till the perish of it. As a kind of biochemical energy, “Passionarity” acts as the Intrinsic motivation of “Ethnogenesis”. From the moment of “Passionate shock”, every ethnic group passes through the same stages of birth, development, climax, inertia, convolution, and memorial at the given time about 1200-1500 years. The “Ethnogenesis of Rus Ethnos” begins from the emergence of Slavs from 1st century AD and ends at 13-15th century with the complete disintegration of Kievan Rus. At the beginning of 13th century, along with a new round of “Passionate shok”, started the “Ethnogenesis of Russian super-ethnos” has continued ever since. The Ethnic contact is an important factor and drives force of “Ethnogenesis”. The “Ethnic field” and “Complimentary” are the basis of Ethnic contact. The positive contact actively promotes the “Ethnogenesis” of the given ethnic group, while the negative patterns impede it, leading the ethnic group to weakness and demise. In Gumilev's theory, 13-15th century, the interaction between Russians and Mongolians was a typical pattern of positive contact, which has an great significance for the formation of Russian super-ethnos. Although Gumilev's theory is just a hypothesis, authenticity has yet to be tested by history. But he greatly expand the research perspective of ethnology, his theory still has an important guiding significance for us to interpret the conflicts and disputes in the world today.
