The Ottoman Public Debt Administration (OPDA) was a unique institution, which introduced capitalist financial principles to the traditional economic life of the Ottoman State. The role of the Administration and its impact on the branches of the state main revenues often become the research subject. There has been a trend to mark a contradictory character of the company. On the one hand the OPDA limited financial sovereignty of the Ottoman State, but on the other hand it improved the general economic development level. Nevertheless, having concentrated on the results, that company archived in its business, scholars failed to pay sufficient attention to its operating measures. That is why it was not very clear what made the OPDA more successful than traditional ottoman financial institutions. Thus the paper aims to fill in this gap by considering official records of the OPDA. Written at the end of the 19th century, in the form of a code for internal use, records represent an important historical source. In order to examine the operational mechanism of the Administration, the paper focuses on the structure and functions of the OPDA, investigates range of duties and competency of its officers, conditions of appointment and dismission, salaries, training opportunities and e.t.c. The author concludes that due to its well-planned organization, high level education and motivation approach, the OPDA developed an effective management model, and helped to raise a new generation of specialists who were not skeptical about European financial experience, and moreover, successfully used it. This study is a part of a growing body of research on European financial management in the 19th century East. Furthermore, it can contribute to future research on economic history.
