Pax Romana – forever?
On the End of a 2000-Year Project
The Roman Legacy
Two hundred years of peace. It sounds like a utopia, like the dream of every peace movement in history. Yet it existed: the Pax Romana, the Roman Peace, which spanned the Mediterranean and large parts of Europe from the beginning of Augustus's reign in 27 BCE to the death of Marcus Aurelius in 180 CE. Within the borders of the empire, relative stability prevailed. Trade flourished. Roads connected the provinces. The law applied — in principle, at least — to all.
Of course, this peace was not peaceful in the modern sense. It was maintained by legions, by the constant threat of military violence, by the subjugation of entire peoples. The peace applied internally; externally, Rome remained a conqueror. And yet: for those living at the center of the empire, the Pax Romana meant a lifetime without the devastations of major wars.

The Continuity of the Roman Project
History knows only a few such periods of imperial stability: the Pax Romana, the Pax Britannica of the 19th century, the Pax Americana after 1945. They are often treated as separate epochs — as if different peoples had independently created similar orders.
But this is an illusion. Every Western-shaped empire is essentially Roman.
The Holy Roman Empire bore the name explicitly. Charlemagne had himself crowned emperor in Rome, in deliberate connection to the ancient tradition. The imperial idea, the emperorship, the notion of a universal Christian order — all transformations of the Roman heritage.
The British Empire adopted the idea of the civilizing mission: the right to govern "backward" peoples — for their own good, of course. Latin remained the language of the elites. Roman law formed the foundation of the educational canon. The British aristocracy raised their sons on Cicero and Virgil, not Shakespeare.
The USA sits in a Capitol, governed by a Senate. Their eagle carries Latin mottos. The architecture of power is neoclassical — columns, domes, marble imitations. The fasces, the Roman bundle of rods as a symbol of state authority, still adorns the speaker's rostrum in the House of Representatives today.
Deeper still: Roman law permeates all Western legal systems. The idea of infrastructure as an instrument of rule — Roman roads, British railways, American sea control and financial networks — is the same. The rhetoric of "Pax" as self-legitimation repeats literally.
The Pillars of the American Order
After 1945, America rose to become the dominant power of the Western world. The Marshall Plan, NATO, the Bretton Woods system, the United Nations — all these institutions bore the American trademark. They created an order resting on three pillars: military strength, economic openness, and liberal-democratic values.
This order was never without contradictions. In Europe and Japan, America appeared as a benevolent hegemon. In Iran, Chile, Vietnam, it showed a different face. Yet compared to earlier empires, America exercised its power with remarkable restraint — at least toward its allies. It was a subtle empire that rarely displayed its imperial nature openly.
Just like Rome.
The End of an Era — or an Epoch?
In 2025, analysts speak openly of the end of Pax Americana. On April 2 — called "Liberation Day" by some — the USA introduced massive protective tariffs that break with the fundamental principles of the postwar trade order. The three pillars of the American world order are crumbling: Military credibility is shaken after Afghanistan. Economic openness gives way to geoeconomism. Democratic values are questioned at home.
Flashpoints everywhere, violence and conflict rising worldwide; countries acting unilaterally against international law — with ever fewer consequences to fear.
— Lawrence Wong, Prime Minister of Singapore, paraphrased
What was once unthinkable has become reality: America is withdrawing from its role as ordering power. Not just as world policeman, but as guarantor of a rules-based system. The message is: America will pursue its interests bilaterally, not negotiate them multilaterally.
But perhaps what we are witnessing is more than just the end of a postwar order. Perhaps a 2000-year continuity is ending.
What Comes After?
The world is entering a new phase that some call Pax Multipolaris — a peace guaranteed not by one hegemonic power but by the precarious balance of several great powers. No single state sets the rules anymore. Stability is maintained through military deterrence and shared fear of existential crises.
China fills the vacuum with its Belt and Road Initiative spanning 140 countries. Russia uses energy resources and military interventions as leverage. Regional powers like the Gulf states pursue independent foreign policies. Europe faces the question of how much strategic autonomy it can afford — and must have.
But none of these actors is Roman in the cultural sense. China carries a Confucian heritage. Russia a Byzantine one. The Gulf states an Islamic one. What is emerging is not a new incarnation of the Roman project, but something fundamentally different: a world order without a Western center.
The Question That Remains
History teaches that geopolitical transitions are rarely peaceful. The Thirty Years' War devastated Europe during the transition from the confessional to the sovereign state system. The collapse of world empires in World War I led to decades of violence. The dissolution of the Soviet Union triggered conflicts that smolder to this day.
The Roman answer to the recognition of impermanence was Stoicism: acceptance of the inevitable, combined with the attempt to act virtuously in the present. Marcus Aurelius, the last emperor of the Pax Romana, wrote in his Meditations:
"Consider always how ephemeral everything is, how worthless. Yesterday slime, tomorrow mummy or ash."
— Marcus Aurelius, Meditations
This perspective is not fatalistic. It is realistic. It liberates from the illusion that any order — however powerful — is built for eternity.
The Pax Romana has fallen. The Pax Britannica is history. The Pax Americana is ending. Perhaps the Roman project itself is ending with it — the 2000-year continuity of Western hegemony stretching from Augustus through Charlemagne, the British Empire, to Washington.
Whatever comes after — whether Pax Multipolaris or new chaos — will also pass. But it will be different. No longer Roman. No longer Western in the old sense.
The work on what is corrupted, which this age requires, begins with accepting this truth: We are living at the end of an epoch, not just the end of an era.
