The work analyzes how maritime supremacy affected the course of revolutionary and imperial conflict across Europe, linking naval operations to continental campaigns, diplomatic maneuvers, and treaty settlements. It reviews coalition warfare and military reverses on land, the upheavals of domestic politics and the emergence of a centralized regime, naval confrontations and neutral‑rights disputes, major expeditions and blockades, and the resulting peace negotiations. Throughout, it argues that control of the seas shaped strategic options, constrained or enabled political aims, and influenced the balance of power between maritime and continental forces.
