Since a few decades ago, especially since collapse of the United Republic of Russia, democracy has found a prominent position among the methods of ruling the world. Therefore studying the process of transition from authoritative regimes to political democratic regimes has turned into one of the significant debates in the contemporary political sociology. The globalization of democratic values on one hand, and the experiences of the political-social evolutions of many countries for establishment or strengthening democracy on the other hand has produced a vast, suitable and scientific literature for the scientific expression of societies’ transition towards democracy. Also, in recent years, the role of social movements within the social-political domain of the societies has increased and the domain of the activities of such movements has expanded from a national level to an international one. Considering these two subjects, this article seeks to offer a theoretical model in expressing the role of social movements, especially the Youth Movement for transition towards democracy in different societies; particularly in the developing communities. This pattern is offered by emphasizing on the new phase of the scientific literature of transition, utilizing the opinions of scholars such as Claus Oufeh, Hauberss, Lacklaew, and Moufeh; while simultaneously emphasizes on internal, international, political, economical and social factors; in order to highlight the role of social movements in this process.
