In the 19th century, the Ottoman Empire encountered land losses and mass migrations. Soil losses caused the borders to change. New borders brought regulations with the Ottoman provincial administration. Various factors were taken into consideration in these administrative arrangements. First of all, the reasons that cause border changes were focused. Places suitable for the resettlement of those who had to migrate from the abandoned places to the Ottoman lands were important in this respect. The immigrants were intended to be resettled as close as possible to their abandoned lands. Also, it was requested to prevent possible attacks from the country on the border. Therefore, an administrative unit suitable for the settlement of the Muslim people who would migrate from Thessaly, which was left to Greece after the 93 War, was established. Servia's proximity to the Greek border enabled it to be both suitable for the resettlement and militarily important. So Servia plucked from the Bitola province. Due to its military importance, it was established as a detached sanjak so that it could communicate quickly with the central administration. In this study, the documents regarding the reasons listed were evaluated and the administrative characteristics of the Servia sanjak were taken into consideration and the arrangements made were tried to be explained.
