Stanak (in original Bosančica: Сmɖɴɖк; Serbo-Croatian Cyrillic: Станак) is the most common name used to refer to the assembly of nobility in medieval Bosnia. The assembly was also known as the Rusag (from the Hungarian word orszag, meaning "country"), Zbor, Sva Bosna (meaning "Whole of Bosnia") or just Bosna, with the officials of the Republic of Ragusa employing several Latin terms as well.
