The study deals with the parish topography of the Dobruška deanery and its clergy until 1436. The focus is on defining the extent of the deanery, the patronages of churches, papal tithes and the distribution of the patronage right. It also deals with the factors associated with the benefice work of clerics. The study focuses on the following issues: who was chosen for presentations; where the clerics came from; how long they worked at benefices; and why their work ended. It also analyzes the careers and mobility of clerics, and with reference to particular cases explains possible motives for exchanging benefices.
The paper deals with the so-called litterae ad beneficia ecclesiastica, that document the institutions of new priests and administrators of churches by the bishop. The aim of the study is to show that the development of form of these documents could be affected by the spreading of the system of patronage rights in the structures of church administration in Prague diocese in the second half of the 13th century.
