The author corrects some deficiencies of existing literature and specifies the chronology of holders of this office. Based on the analysisi of sources are also reconstructed purviews and areas, in which the land captain could intervene and their changes in time of hussite wars and reign of different margraves. This work also captures the way of appointment and deposition of land captains by the ruler and different strategies and attempts to alternate arrangement of administration of Moravian margravate by Sigismund of Hungary, when he tried to sideline this office, which became more and more dependent on the forming high nobility estate.
