The Book
From maritime freedom to effective control
A historical, legal, technological and geopolitical inquiry into whether the physical conditions that sustained freedom of the seas are beginning to change.
Denizlerin Fethi Çağı
Mare Liberum'dan Mare Dominium'a
The book traces the long tension between Mare Liberum and Mare Clausum, and asks whether satellites, persistent surveillance, unmanned systems, precision weapons and strategic chokepoints are altering the practical meaning of maritime freedom.
It brings together sea power, maritime law, global trade, energy security, emerging technology and the transition toward a multipolar international order.
“History has not yet recorded the conquest of the seas.” The key word is yet.
The book asks what happens when maritime spaces remain legally free but become increasingly controllable in practice.

Core Concept
Mare
Dominium
Formal legal freedom may increasingly coexist with effective technological and strategic control at sea.
For centuries, the difficulty of monitoring and controlling vast maritime spaces helped sustain the material conditions behind the freedom of the seas. Persistent sensors, satellites, unmanned systems, long-range precision strike and control of strategic chokepoints are changing that reality.
Mare Dominium describes an emerging condition in which a state need not formally own maritime space to acquire the capacity to monitor access, raise the cost of unwanted presence and exercise effective control.
