Derbendcis
Derbendcis were the most important and largest Ottoman military auxiliary constabulary units usually responsible for guarding important roads, bridges, fords or mountain passes. Usually, the population of an entire village near some important pass would be assigned with derbendci status in exchange for tax exemptions.
Etimology
The name is derived from a Persian word Dar-band meaning "pass", "gateway" or "closer of the door".
History
The Ottomans had common practice to exempt some of their tax-paying subjects (rayah) from paying certain taxes in exchange for some services. In case of derbendcis this also included military services such as guarding mountain passes. Usually the entire villages were assigned with this duty and exempted from paying war time taxes (Turkish: avariz-i divaniyye), customary taxes (Turkish: tekdlif-i 'orfiye), service as oarsmen in the Ottoman navy and devşirme of their boys into janissaries. In the region of northern Macedonia at least 175 villages had derbendci status and enjoyed these kind of tax exemptions. Sometimes the Ottoman state "created" villages around derbend territories while in some cases the existing villages applied to their kadı to receive derbendci status in exchange for providing security, constructing or maintaining roads and bridges. Newly settled population of such villages was not exempt from paying avariz taxes.
