Özet:

During the reign of Ahmed III, military structures such as castles and fortifications along the borders were overhauled and repaired for various reasons. One of the repaired fortresses was the Baghdad fortress on the Iranian border. The Baghdad fortress was of great political, economic, social, cultural, religious and military importance for the Ottoman Empire. Located at the center of the military conflict between the Safavid Empire and the Ottoman Empire, the castle was repaired many times by the Ottomans in order to maintain sovereignty in Mesopotamia, to ensure border security, and to be used as a military logistics base during expeditions to the east. The size of these repairs is directly proportional to the size of the ruined parts of the castle. Some architectural additions could also be made in case of new needs in the castle. This study focuses on the repair of the Baghdad Castle, which had become dilapidated over time during the reign of Sultan Ahmed III, which began in 1722 and copmleted in 1723. By examining the archival documents and sources of the period, the study aims to determine the repaired and newly added parts of the fortress, the materials and labor costs for the construction, starting from the discovery process, and to determine how much Ottoman economic resources were spent for these repairs.
