Delminium was an Illyrian city and the capital of Dalmatia which was located somewhere near today's Tomislavgrad, Bosnia and Herzegovina, under which name it also was the seat of a Latin bishopric (also known as Delminium).[1]
The coast and hinterland of central Dalmatia up to and beyond the Dinaric mountains was inhabited by the Delmatae, after whom the Roman province Dalmatia was named, their own name being derived from their principal settlement Delminium near Duvno.
