The medieval archdeaconry of Požega was a church-territorial unit of the diocese of Pécs, which was approximately located in the area of today's Požega diocese. It covered the area from the northwestern peaks of Papuk and Psunj to Našice in the east and the Sava River in the south. The seat of this church-territorial unit was in the present-day village of Kaptol, north of Požega. Chapter of Saint Peter was also a locus credibilis, and numerous documents related to the work of this chapter and archdeaconry have been preserved from the Middle Ages. The basic goal of the diploma thesis defines the church law situation in the area of the administrative unit of the Požega Archdeaconry. It was described with the help of available sources and relevant literature. With the help of the list of church tithes from 1332., 1333., 1334. and 1335, the parishes and churches within the archdeaconries were listed and located, and their dense distribution was noticed. Požega chapter was also considered, as well as the church orders that are present in the area of the county and the archdeaconry.
