context_page_description: Zachlumia or Zachumlia, also Hum, was a medieval principality located in the modern-day regions of Herzegovina and southern Dalmatia. In some periods it was a fully independent or semi-independent South Slavic principality. It maintained relations with various foreign and neighbouring powers and later was subjected to Kingdom of Hungary, Kingdom of Serbia, Kingdom of Bosnia, Duchy of Saint Sava and at the end to the Ottoman Empire.
context_section_description: In the beginning of the 15th century, Hrvoje Vukčić Hrvatinić ruled over the western Hum, and Sandalj Hranić Kosača ruled over its eastern part, while the Neretva river remain a border between their possessions.
  Bosnian regional lord Stjepan Vukčić Kosača who ruled over Zahumlje, in 1448 dropped his title "Vojvode of Bosnia", assuming the title "Herceg [Duke] of Hum and the Coast". He changed it again in 1449 to "Herceg of Saint Sava" in recollection of the Serbian saint. This title had considerable public relations value, because Sava's relics were consider miracle-working by people of all Christian faiths. His lands were known as Herzog's lands or later Herzegovina.
  In 1451 he attacked Dubrovnik, and laid siege to the city. He had earlier been made a Ragusan nobleman and, consequently, the Ragusan government now proclaimed him a traitor. A reward of 15,000 ducats, a palace in Dubrovnik worth 2,000 ducats, and an annual income of 300 ducats was offered to anyone who would kill him, along with the promise of hereditary Ragusan nobility which also helped hold this promise to whoever did the deed. Stjepan was so scared by the threat that he finally raised the siege.
