This article starts with a brief analysis of the causes of state collapse as states undergo the process of political evolution. Next, I describe and analyze the mechanisms of social-political crises arising in the process of modernization. Such crises are a consequence of the inability of many traditional institutions and ideologies to keep up with changes in technology, communication, system of education, medical sphere, and with the demographic change. This analysis suggests that an accelerated development can cause a system crisis with potentially serious consequences to the society. It is important to take this aspect into consideration because some scholars insist that the economic reconstruction and development are necessary for nation-building. This actually implies a rapid economic advancement (otherwise, the economy could not be re-constructed and developed). However, one should not ignore the possibility that very rapidly developing countries may run the danger of falling into the trap of fast transformation. The present article describes several mechanisms that can contribute to sociopolitical instability, including social tensions arising from rapid urbanization, youth bulges, and 'resource curses'.
