In the sanjak of Hudâvendigâr, one of the first established Ottoman sanjaks, compared to the other administrative units of Anatolia and Rumelia the management system has a different structure due to the width of the areas allocated to the khass-i sultan (domain of the sultan) and endowments of Ottoman sultans. The sanjak ruler of Hudâvendigâr had no administrative authority in this structure in the city. The Subaşı of Bursa wasn’t appointed by the ruler of sanjak. Since the city was khass-i sultan, the security of the city and the revenues (bâd-i hevâ) of this service (zeamet mukataası) operated through iltizam. Although this mukataa was given to the sanjak ruler of Hudâvendigâr ruler from time to time in the 16^th century, this was not a permanent practice. Many studies have been conducted on the administrative organization in Bursa throughout the 16^th century and the issues about the scope of authority. Nonetheless, it is evident that the rate of records pertaining to the subaşı of Bursa in court registers significantly declined over the 17^th and 18^th centuries. In other words, while the administrative divisions remained same throughout the sanjak or in Bursa after the 16^th century, it seems that there existed a change in terms of maintaining the city’s security. In this study, an analysis on this change will be presented. Based on Bursa kadi records, how the security of the city was ensured, especially in the 17^th and 18^thcenturies, and the reasons for this change from the 16^th to 18^th centuries will be questioned.
