Social civil movements that were devoted to change the power started at the Middle East region in Tunisia and then exercised control over many Arab countries, which has led to the beginning of a new period in the region. In this article we will discuss the new period in question and make a study of some subjects from the management changes in the countries such as Tunisia, Egypt, and Libya that have experienced "Arab Spring" in recent history to the events leading to civil war in some countries such as Syria. Within this framework, we will explain why the period has been called under such a name and tell the events encountered in general terms under the title of "What is the Arab Spring?" Then we will evaluate the reasons of the Arab Spring in the political, social and economic categories and analyze these factors. Following this, we will discuss the political and governmental structures of the countries, Tunisia, Egypt, Libya and Syria before the Arab Spring within the scope of oppressive leadership structures of these countries. Finally, we will evaluate the governmental structures of Tunisia, Egypt, Libya and Syria after the events and these ongoing periods comparatively with their pasts and try to answer the question of "Did the Arab Spring manage to democratize the oppressive regimes?"
