The Glamoč area has been inhabited since at least Neolithic times. In the late Bronze Age, the Neolithic population was replaced by more warlike Indo-European tribes known as the Illyrians, specifically the Dalmatae. Their capital was Delminium, which was located in today's Tomislavgrad. The Dalmatae left many artifacts which allow us to learn about their presence in this area. The most important remains are the "gradine", remains of Illyrian settlements which were distributed along the Glamoč field. 34 gradinas were found on the territory of Glamoč. The settlements were strategically placed for defence. The Romans took over 200 years to occupy this region.
