This thesis explores different factors affecting the democratic backsliding process in today's world, where a cult of personality is established by using populism as the essential tool for achieving their goals. Considering the importance of weakening the checks and balances system, it also sheds light on other factors as the structure of the internal party organization, personalization of politics, and the political culture. Conducting a comparative case study analysis on Turkey and Hungary, this research aims to take a step forward in the democratic backsliding literature. Taking one step forward from the argument that democratic backsliding takes place when the checks and balances system abolishes, the research asks, "what happens after supposing that such governments do not fit the doctrine of separation of powers?" Through examining Turkey and Hungary as examples of hybrid regimes taking steps toward democratic backsliding day by day under AKP’s and Fidesz’s rule, the research seeks an answer to the question of "after diminishing the checks and balances system, what takes place and affects the democratic backsliding process in such examples?"
