Ahmet Hasim, one of the leading figures of the Turkish literature, has always been of particular interest as a poet and prosaist to literary literature researchers. His childhood years spent with his mother's intense love, his painful adaptation to a new social environment after moving to Istanbul and starting Galatasaray High School, and his ugly duckling complex offered him and literature researchers a great wealth of material. Indeed, Hasim's family setting and emotional challenges in the adolescence left deep traces in his life, prose, and poetry. To discover these traces, this study employed the concept of inferiority complex coined by Viennese psychiatrist Alfred Adler. Using this concept, the study sought to shed light on both the personality of the artist and his works. Every person has the existential sense of lack which turns into an inferiority complex if it is not transformed into a source of motivation through abilities and capacities. Consequently, people feel worthless and incompetent. Then, they exhibit aggressive attitudes like anger, arrogance, ambition, and pride to get rid of this feeling or stay away from others to feel privileged. Hasim did not manage to overcome the feeling of inferiority. Because he was neglected by his father and raised by an exaggerated love and care of his mother. As a result, he developed aggressive behavior and stayed away from people to feel superior. This study attempted to identify the causes and manifestations of Ahmet Hasim's inferiority complex.
