The era of late 1980s and early 1990s is the most significant turning point in the politics of Croatia's modern history. During that time period, Croatia has transitioned from a communist into a democratic regime, and simultaneously established independent and sovereign Republic of Croatia. On the beginning of this thesis I will provide the basics of transitology, political science discipline regarding political regime transitions. The context for transition will be history of SFR Yugoslavia, focusing on SR Croatia, with an emphasis on social issues and political events that have determined main reasons for SFR Yugoslavia's dissolution. Furthermore, following the escalation of problems, social disparities, and nations' inclinations towards emancipation, the very process of transition from socialist to democratic regime will be described. A brief review of the social homogenization phenomena will follow, as well as analysis of aforementioned transition through the framework of transitology. Finally, the thesis provides a brief analysis of the Republic of Croatia in its post-transitional period and its orientation towards the Euro-Atlantic integrations .
