Sport, one of the dynamics of social and cultural life, begins with humans encountering the natural conditions, adapting to them, gaining dominance in nature, and developing their bodies and muscles as the only means to protect themselves. The founder of the Republic of Turkey, Mustafa Kemal Atatürk, developed an interest in sports during his military student years and remained involved in sports activities throughout his life as both a spectator and practitioner. Particularly successful in physical education, equestrianism, and marksmanship, Atatürk did not hesitate to provide financial and moral support to the development of Turkish sports, thanks to his close interest in wrestling, javelin throwing, horse racing, and water sports. Believing that success could be achieved through the adoption of sports by the youth and the wider population, Atatürk made physical education compulsory in all schools and emphasized the importance of nurturing intelligent, agile, and ethical young individuals. This study examines the developments in the field of sports from the Constitutional Monarchy to the Republic and aims to reveal Mustafa Kemal Atatürk's support for Turkish sports during this period by analyzing research works based on documents, speeches, and statements, as well as secondary sources.
