Prince-Bishopric of Montenegro was аn ecclesiastical principality that existed from 1696 until 1852. It emerged from the Serbian Orthodox bishops of Cetinje, later metropolitans, who renounced Ottoman overlordship and transformed the parish of Cetinje to a Russian de facto protectorate, ruling as Metropolitans (vladika, also rendered "Prince-Bishop"). The history starts with Danilo Šćepčević, a bishop of Cetinje who united several clans of Montenegro into fighting the Ottoman Empire that had occupied most of southeastern Europe. Danilo was the first of the House of Petrović-Njegoš to occupy the office as Metropolitan of Cetinje until 1851, when Montenegro became a secular state (principality) under Danilo I Petrović-Njegoš. Also, it became a brief monarchy when it was temporary abolished 1767–1773, when impostor Little Stephen, posed as Russian Emperor and crowned himself Lord of Montenegro.
