Mustafa Kemal Pasha, the leader of the National Struggle, determined the philosophy of the National Struggle as "making the national will sovereign" during the period of congresses and based on this philosophy, the National Struggle was carried out through a parliament. After the war this philosophy was completed successfully with Republican administration. So in this study, it is aimed to identify the features of this philosophy, which started to take an important place in the politics of the country after Mustafa Kemal Pasha period. Acting in line with this purpose, the study also tries to examine whether this understanding of national will was inspired by the “general will” approach of Jean-Jacques Rousseau and what kind of approach it had regarding democracy and freedom. In this context, firstly a comparative and analytical analysis has been made based on the main books of Rousseau that includes his “general will philosophy” and the books that include Mustafa Kemal Pasha's discourses on his understanding of national will. Afterwards, using various researches on the subject, the position of the concept of national/ general will in terms of democracy and freedom debate was tried to be discussed. As a result of these evaluations, it has been supposed that the general will and national will concepts used by Rousseau and Atatürk have significant similarities by various aspects. It has also been claimed that these ideas are a part of a republican democracy, but not a liberal democracy.
