From the 7th century BCE, bronze was replaced by iron, after which only jewelry and art objects were still made out of bronze. Illyrian tribes, under the influence of Hallstatt cultures to the north, formed regional centers that were slightly different. Parts of Central Bosnia were inhabited by the Daesitiates tribe, most commonly associated with the Central Bosnian cultural group. The Iron Age Glasinac-Mati culture is associated with the Autariatae tribe.
