Royal surnames; Kotromanic, Kosaca, Tvrtkovic and Pavlovic after arrival of Ottoman Turks changed in; Terzic(around Visoko), Kulenovic(West Bosnia), Zildzic(around Zenica), Rizvanbegovic(South Bosnia) etc... There were four main royal families in medieval Bosnian kingdom but they all changed their surnames upon conversion to Islam. These four families are known as the oldest royalty of Europe and irony is that today even Bosnian people know very little about them though there are so many alive desendents of royal ancenstry especially in valleys of Central Bosnia and highlands around;(Sarajevo, Visoko, Vares, Breza, Olovo, Kakanj, Zenica, Travnik, Vitez, Fojnica)etc... Bosnian government is totaly ignorant towards royal rights and after an silent and covered up outbreak of royalist movement several years ago many nobles are deteined, terrorised and denied any claims for title or land... Yet, there is the heir of the Bosnian throne still alive and he is last male descendent of Bosnian medieval kings. He is last Bosnian noble who can claim the throne regularly called 'Prince' by few close assistants who know him and his whereabouts. Prince of Bosnia is 29 years old and lives ordinary life somewhere in Asia probably afraid to ever reveal his true identity.
