Prince-Provost
Prince-Provost is a rare title for a monastic superior with the ecclesiastical style of provost who is a Prince of the Church in the sense that he also ranks as a secular 'prince' (lato sensu: ruler), notably a Prince of the Holy Roman Empire (Reichsfürst), holding a direct vote in the Imperial Diet assembly coequal to an actual Prince-abbot, as in each case treated below.
