The New Middle Ages And The Shape Of Global Order

To understand the ongoing transformations in the international system, it is useful to adopt the global configuration of power as a central interpretative key. Political power is not distributed in a stable or permanent way, but reorganizes itself over time according to different patterns. It can expand or contract—like an accordion. In certain historical phases, power tends to concentrate in centralized structures, capable of ensuring order, predictability, and security across vast areas.

In other moments, however, the center loses strength, and a polycentric configuration emerges in which the ability to provide public goods—security above all—becomes fragmented across multiple levels, actors, and territories. The current historical phase appears to fall into this latter category. The United States, which for decades has acted as the central power and global provider of security, is increasingly hesitant to maintain this role. This uncertainty pushes regional, sub-state, and private actors to equip themselves with their own tools for defending their interests—much like what occurred after the decline of the Roman Empire, when citizens and local communities had to provide for their own protection.

In such a scenario, one can no longer speak of a unified international order, but rather of a plurality of overlapping and coexisting orders. The idea of a “new Middle Ages” thus refers to a transformation of the political and social order, not to a return to disorder. It points to the progressive reduction in the effective reach of sovereignty, the waning of the United States’ central role as global organizer, and the growing inability of multilateral institutions to guarantee public goods at the global level. In this context, the protection of communities and infrastructures increasingly falls to local actors who define their own boundaries—physical or digital—in order to establish autonomous defense mechanisms.

In a world marked by instability, uncertainty, and the absence of supranational guarantees, new strategies emerge based on proximity, self-organization, and localized threat management. The resulting framework is fragmented, but not irrational.
