Duchy of Saint Sava (Latin: Ducatus Sancti Sabae, Bosnian and Croatian: Voјvodstvo Svete Save, Serbian Cyrillic: војводство Светог Саве) was a late medieval monarchy amid the Ottoman conquest of the Balkans. It was ruled by Stefan and his son Vladislav, of the Kosača family.
The first ruler was titled "Voivode of Saint Sava" (after the first Serbian Patriarch, Saint Sava), his rank in German – Herzog (Duke), would later give the name to the present-day region of Herzegovina, thus it has also been named the "Duchy of Herzegovina" in modern sources, as the Ottomans used Hersek Sancağı ("Sanjak of the lands of the Herzog"), the Sanjak of Herzegovina.
In a document sent to Holy Roman Emperor Frederick III on 20 January 1448, Stephen Vukčić Kosača styled himself "Duke of Saint Sava (Vojvoda Svetog Save), lord of Hum and Primorje (Gospodar Humski i Primorski), Grand Duke (Herzog), and forced the Bosnian kingdom to recognize him as such. This title had considerable public relations value, because Sava's relics were consider miracle-working by people of all Christian faiths in the region.
On 15 February 1444, Stephen signed a treaty with Alfonso V, King of Aragon and Naples, becoming his vassal in exchange for the king's help against Stjepan's enemies, namely King Stephen Thomas of Bosnia, Duke Ivaniš Pavlović and Venice. In the same treaty Stjepan promised to pay regular tribute to Alfonso instead to Ottoman sultan as he had done until then.
Stjepan Vukčić died in 1466, and was succeeded by his eldest son Vladislav Hercegović. In 1482 he was overpowered by Ottoman forces led by Stjepan Vukčić's youngest son, Hersekli Ahmed Pasha, who converted to Islam prior to that. In the Ottoman Empire, Herzegovina was organized as a province (sanjak) within the state (pashaluk) of Bosnia. The name of the country was changed to Bosnia and Herzegovina in 1853, as a result of a twist of political events. It was part of the Ottoman Empire for a bit less than four centuries.
