The dimensions of the intervention of Istanbul, which was the capital of the Ottoman Empire in the social and economic life of the provincial cities in both Anatolia and Rumelia geography, have not been adequately examined within the framework of the discipline of history. These settlements undoubtedly had a touch on the life of the capital. This article examines the weight of Istanbul on the city and countryside of Kütahya over a decade in the second half of the eighteenth century. The reason for keeping the time limits so short is to see the dimensions of the capital city's activity more clearly by keeping the lens deeper as much as possible. As a result of the findings, although the active presence of the capital in the countryside is clearly felt, the beneficial sociological and economic relations of the residents of the two cities are seen. For this reason, it can be said that there is no one-way traffic in joint relations. The archive documents of the historical period examined in the study are the main sources that are used as broadly as possible without exceeding the limits of the article.
