This article is an attempt to present the role of colonisation in the Roman policy of expansion towards its Italian neighbours in the 3rd–2nd BCE and showing the effects of this phenomenon, as illustrated by settlements in the Ager Gallicus and Picenum. Information on the founded colonies in sources, appearing somewhat on the margins of accounts of military activities and diplomatic missions in Italy (foedera), but also connected with the internal policy conducted by Rome (grants of land), may indicate that colonisation complemented such activities. This complementary character of the process of colonisation in relation to other political, military, diplomatic, and internal activities seems to be an important feature of the Republic’s activities.
