The aim of this volume is to examine various forms of adaptation adopted by coastal societies in the ancient Mediterranean in response to external pressures they occasionally experienced. The investigation spans the longue duree stretching from the epi-paleolithic to the Medieval period. Special attention is given to the impact of two groups of variables: climate and sea level changes on the one hand, and fluctuations in political circumstances connected with the domination of empires, on the other hand. For adaptation, the volume analyses modes of coastal residence, subsistence, and maritime connectivity, not as a static feature, constant throughout history, but as a process that requires permanent adjustments due to changes in environmental, social and political conditions. Methodologically, various forms of case studies are employed, isolating thematic issues, geographic micro-regions, temporal boundaries, and disciplinary perspectives, ultimately seeking to embrace as wide an array of phenomena as possible in the human experience of collapse and adaptation.
