THE DANUBIAN REGIONS

UNDER this heading we include all the provinces watered by the Danubius of the Celts, the Ister of the Greeks.1 Their common destiny was a result of the shipping industry on the river and, still more, of their close kinship with the tribes established beyond its left bank, their rapacious instincts, and their frequent attempts to force the frontier of northern Italy. The necessity of defending the peninsula and its capital on this side helps us to understand the beginning of the Roman conquest, its progressive extension and the changes of policy in regard to it. This solidarity of the Danubian territories has already been demonstrated by Mommsen;2 we have only differed from him in excluding the Roman protectorate over the Greek colonies of South Russia, which had a different origin and was more closely connected with the provinces of Anatolia.
