For as long as humanity has ventured on the seas, naval warfare has been an integral part of their activities and the focal point for many histories and ideas of heritage. This book presents a rarely explored aspect: the long‑term impact of those battles on shorelines, seas and oceans.

Dramatic and altering, the physical scars of battles remain with us today in the form of cultural landscapes and archaeological sites, while the geopolitical consequences of warfare have been world‑changing. The migrations of peoples across the seas, accompanied by violence, have done more to shape the demographic and cultural map of the modern world than almost anything else. Both seaborne opportunities and threats have influenced the way of life of coastal communities. Today, technology has seen these threats extend far into the deepest ocean and reach across continents. This book shows how, despite being virtually invisible to an increasing percentage of the world’s population, the ocean is more significant now than it has ever been.

Ranging from the world of antiquity to the present day with a global perspective, the volume is intended to appeal to those interested in history, archaeology, social sciences and the environment.
