Abstract This study examines the evolution of military education and professionalization in modern Greece, with a specific focus on the Evelpidon Military Academy, founded in 1828, and its role in shaping the Greek Army. The academy, established by Ioannis Kapodistrias, served as the cornerstone for developing a disciplined and capable officer corps, crucial for Greece’s transition from a nascent state to a modern nation. This research explores how Evelpidon’s curriculum evolved over time, reflecting shifts in military science and the demands of national defense. A key theme of the study is the influence of foreign military doctrines on the Greek military. French advisors initially guided its development, with later contributions from German, British, Italian, and Soviet military traditions shaping training methods, organizational structures, and tactical doctrines. By analyzing these influences, the study highlights the dynamic interplay between domestic needs and external models in professionalizing the Greek armed forces. The findings underscore the academy's dual role as an educational institution and a tool of state-building, promoting unity and modernization. This research contributes to broader discussions on the role of military education in national development and offers insights into the challenges of professionalizing emerging military systems.
