In the borrowing policies of the Ottoman Empire, especially in domestic borrowing, Galata Bankers emerge as the most important element of an era. It is seen that Galata bankers are evaluated in different ways in the literature. Therefore, the absence of a common judgment on this issue makes it necessary to examine the families that make up Galata bankers. In this context, the subject of the study is the Baltazzi Family, which has an important place among Galata bankers. The strong place of Galata bankers in the Ottoman financial system is a natural result of the economic and financial developments of the Ottoman state in the historical process. Because the institutional deterioration in the economic and financial structure did not give the desired result despite all the modernization and reform efforts. Besides, the uprisings, lost wars, and land losses caused the financial system to deteriorate thoroughly. The current situation has caused the issue of borrowing to come to the fore even more. The source of the borrowing was Galata bankers consisting of non-Muslim families in the relevant period. The resources provided here have brought the financial system to a better point than the current situation. The Baltazzi family is one of the families that had the best relations during this period and provided the most resources to the Ottoman state.
