Area of Imotski was under Ottoman rule for more than two centuries and in that time Ottomans left their mark through documents made by Ottoman administration. Those documents are mainly defterler which registered villages and nahiyas located on Imotski area. Those documents are of financial nature and their main role was to keep Ottoman tax system under control, especially because various taxes were main source of income to Ottoman treasury. This paper shows defterler from different time periods (1477., 1585. and 1701.) and comparisons between some of the villages which are registered in different defterler. One of the questions raised from Ottoman defterler is location of some of the villages and some authors have different answers on that question. Besides defterler, this paper shows some Ottoman documents directed towards Franciscians from Imotski who lived in the monastery „on the Island“. Those documents show how local authorities treated Franciscians, as well as sometimes bad relations between Franciscians and Muslim population. Besides that, these documents say something about monastery itself (various repairs on buildings, etc.). Franciscian flights from Imotski are proving that coexistence between Franciscians and Ottoman administration was very difficult at times. With the liberation of Imotski from Ottoman rule in 1717. majority of Muslims left this area, while local population led by Franciscians started coming back.
