Bosnian Ban Kulin no relation knez Krvaš
The Charter of Ban Kulin (Bosnian-Serbian-Croatian: Povelja Kulina bana / Повеља Кулина бана) was a trade agreement between the Banate of Bosnia and the Republic of Ragusa that effectively regulated Ragusan trade rights in Bosnia, written on 29 August 1189. It is one of the oldest written state documents in the region.
According to the charter, Bosnian Ban Kulin promises to knez Krvaš and all the people of Dubrovnik full freedom of movement and trading across his country. The charter is written in two languages: Latin and an old form of Shtokavian dialect, with the Shtokavian part being a loose translation of the Latin original. The scribe was named as Radoje, and the script is Bosnian Cyrillic (Bosančica).
