The present Russian political system is tied up with Putin's name; and Putin is consi-dered as a full-fledged political reality. Today's powerful Russia, which has got a new life after the Cold War and the weak collapse period, and has a major impact on global developments including the Middle East, is not understandable except under this title. What inspired writers to analyze Putin's performance is to study the causes of the exis-tence of a personality such as him and the formation of Putinism in today's Russian so-ciety. Knowing the performance of Putin and Putinism requires a clear answer to some questions like, why the phenomenon of Putinism in the 21st century whit democratic structure has emerged and persisted, and what is Putinism at all? The hypothesis that will be presented to understand this issue is that the long-standing political culture of Russia and the geographical and historical imperative of Russian nation have led to the emergence and continuation of Putinism in today's Russian society, as well as the secu-rity and economic problems of the 1990s, humiliation, pressure, and blockade of the west against Russia is the mainstay of the emergence and continuation of Putinism. To investigate the hypothesis of research, firstly we examine the system of pseudo-democracy and then we will discuss Putin's functions and behaviors in the economic, political, and social spheres. Finally, we will discuss about the Russian domestic context and the external factors that led to the formation of Putinism.
