At the end of the Pre-archaic era, the Greeks began to settle on the shores of the Mediterranean and the Black Sea. It was an economic-political process that involved exploring new areas and selecting territories that seemed promising for the establishment of a settlement. From the 8th to the 6th century BC, i.e. at the same time when new settlements sprang up on the coasts of Italy, Sicily, the Black Sea, North Africa, and elsewhere, interest in settling on the Adriatic was much feebler. This dissertation aims to study and analyze geographical, social, and economic circumstances that can be highlighted as the main arguments for the lack of Greek motivation to colonise the Eastern Adriatic until the 4th century BC. The thesis consists of six major parts. The introduction is followed by a review and re-evaluation of hypotheses about the Greek presence in the Adriatic until the turn of the 5th and 4th centuries BC. The following section focuses on general knowledge of Greek prospection and colonisation during the Archaic period. That unit is followed by three sections in which the Eastern Adriatic geographical features, economic potentials, and social circumstances are separately analyzed. By employing contemporary theoretical models such as the concept of the narrow sea networking, economic relations of the center and periphery, the concept of supply zones, comparative advantage theory, and the middle ground, we sought to highlight the strong interdependence of geographical, economic, and social factors on the development of communication dynamics between Greeks and indigenous people of the Eastern Adriatic. Moreover, the analysis pointed to the important role of geographical features and their repercussions on the native economy and society. The general argument is further strengthened by comparison with similar or concurring examples that have emerged from the contemporary study of the Greek settling process in the Archaic period. The result of the research is a fresh explanatory framework of socio-economic affairs in the Eastern Adriatic during the first half of the first millennium BC whose essence is strikingly reflected in the relatively long absence of Greek interest in intensive commercial exploitation and establishment of permanent emporia or settlements.
