Abstract
Hurufat registers are important archival documents that show the regional practices in a city. The dervish lodges and zawiyas in Izmit were recorded in those registers between 1711-1806. This study mainly focused on four dervish lodges, three zawiyas, and one tekke. The units in the derwish lodges and zawiyas that have survived today are shrines and public baths. According to the obtained registers, the dervish lodges and zawiyas in the Izmit district were mostly located in the central neighborhoods, and a few were in villages and hamlets. This study dealt with four dervish lodges, three zawiyas, and one tekke. As can be read in the registers, the study findings showed that the sects of "Mevleviyye," "Halvetiyye," and “Bayramiyye” had several lodged and zawiyas in the city that were categorized under three groups (i.e., dervish lodge, zawiya, and tekke) in our study. The name and duty of founders (bâni) in archival documents are acknowledged as historical documents. This study aimed to present information about the appointments, positions, founders, and assets in structures that have not survived to the present day, thus enlightening the period. It also gave information about the restorations, construction plan and material, and the current status of the surviving dervish lodges and zawiyas, supported with images, archive documents, and field research findings. The mentioned structures (i.e., the dervish lodges and zawiyas) were architecturally classified in the light of archive documents and old images. The regional plans were also considered in describing the locations of the lodges and zawiyas in the city. In this sense, the topographical and architectural information about the dervish lodges and zawiyas in İzmit was valuable information sources.
