contemporary grammarian Velius Longus highlights in his treatise about orthography that the correct form of Dalmatia is Delmatia, and notes that Marcus Terentius Varro who lived about 2 centuries prior of Appian and Velius Longius, used the form Delmatia as it corresponded to the chief settlement of the tribe, Delminium. The toponym Duvno is a derivation from Delminium in Croatian via an intermediate form *Delminio in late antiquity. History The Delmatae appear in historical record in 181 BC. The death of Pleuratus III of the Illyrian kingdom and the succession by his son Gentius led the Delmatae to not recognize his rule and secede altogether. The Daorsi, who lived to the south of the Delmatae did the same. Over the centuries, the Delmatae and Ardiaei were among the Illyrian groups which expanded their territory northwards at the expense of the Liburni. They Delmatae may have been originally pushed towards the coast because of Celtic migrations in Pannonia Strabo writes that the territory of the Delmatae was divided into an inland (present-day Tropolje) and a coastal region by the Dinaric Alps. Their capital settlement Delminium was located close to present-day Tomislavgrad. The first Dalmatian war in 156 BC – 155 BC finished with the destruction of capital Delminium by consul Scipio Nasica. The second Dalmatian war was fought in 119–118 BC, apparently ending in Roman victory as consul L. Caecilius Metellus celebrated triumph in 117 BC and assumed his surname Delmaticus. The third Dalmatian war 78–76 BC finished with the capture of Salona (port Solin near modern city Split) by the proconsul C. Cosconius. During the Roman Civil War of 49–44 BC, the Delmatae supported Pompey against the coastal Roman colonies which supported Caesar and continuously fought against the Caesarian generals Gabinius and Vatinius. After Pompey's defeat they continued to fight against Roman legions in Dalmatia. The fourth and final conflict occurred 34–33 BC during Octavian's expedition to Illyricum because of their iterative revolts, and finished with the capture of the new Delmatian capital- Soetovio (now Klis). The last revolts of Delmatae under their federal leader Bato, against Romans were in 12 BC and the Great Illyrian Revolt in 6–9 AD; both also failed and finished by a terminal pacification of bellicose Delmatae. Cohors Delmatarum In Roman Imperial times the Dalmatae formed numerous Roman auxiliaries: Cohors I Delmatarum Cohors I Delmatarum milliaria equitata Cohors II Delmatarum Cohors III Delmatarum equitata c.R.
