The issue of the state and statehood is a principal one in social studies, whatever its aspect we consider. In this respect it is worth pointing out the growing interest to the problems of nation-building and state-building. So the state-building is regarded as a key objective, particularly in ‘fragile states’. At the same time we should agree with Peter Turchin, that ‘nation-builders today do not have such a theoretical framework’, while conceptual weakness of the nation-building theory can be diminished with the help of evolutionary science. The present article attempts to advance a bit in this regard.
