The Ban Kulin Charter - a centuries-old trade agreement between medieval Bosnia and Dubrovnik, which is one of the oldest diplomatic documents not only in BiH but the entire region, is marking the 833rd anniversary.

According to the charter written in the Bosnian Cyrillic script, the Bosnian ruler of that time, Ban Kulin, had promised the people of Dubrovnik full freedom of movement and trading across his country.

Ban Kulin's rule is believed to be the most representative of Bosnia's golden age, which made him a common hero of Bosnian national tales.
Three copies of the document that is often dubbed ‘Bosnia's birth certificate’ have been saved to date but none of them is in Bosnia.

A copy believed to be the oldest one is in a museum in Saint Petersburg, while two other copies, which the historians claim to be of a more recent date, are in Dubrovnik.

The only sample that can be seen in Bosnia is not original and is displayed in the National Museum of Bosnia and Herzegovina in Sarajevo.
