 Stjepan Vukčić Kosača in 1448 dropped his title ""Vojvoda" of Bosnia", assuming the title "Herceg of Hum and the Coast".He changed it again in 1449 to "Herceg of Saint Sava" in recollection of the Serbian Orthodox saint.This title had considerable public relations value, because Sava's relics were consider miracle-working by people of all Christian faiths.
