From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The turbulent peoples also, who had possession of the district along the Illyrian coast, gave their Roman masters constant employment. The Dalmatians, even at an earlier period the most considerable people of this region, enlarged their power so much by admitting their neighbours into their union, that the number of their townships rose from twenty to eighty. When they refused to give up once more the town of Promona (not far from the river Kerka), which they had wrested from the Liburnians, Caesar after the battle of Pharsalia gave orders to march against them; but the Romans were in the first instance worsted, and in consequence of this Dalmatia became for some time a rendezvous of the party hostile to Caesar, and the inhabitants in concert with the Pompeians and with the pirates offered an energetic resistance to the generals of Caesar both by land and by water.
Lastly Macedonia along with Epirus and Greece lay in greater desolation and decay than almost any other part of the Roman empire. Dyrrhachium, Thessalonica, and Byzantium had still some trade and commerce; Athens attracted travellers and students by its name and its philosophical school; but on the whole there lay over the formerly populous little towns of Greece, and her seaports once swarming with men, the calm of the grave. But if the Greeks stirred not, the inhabitants of the hardly accessible Macedonian mountains on the other hand continued after the old fashion their predatory raids and feuds; for instance about 697-698 Agraeans and Dolopians overran the Aetolian towns, and in 700 the Pirustae dwelling in the valleys of the Drin overran southern Illyria.
