The Westphalian monopoly on violence
The principle that the state, and only the state, may use organised violence inside its territory or licence others to do so — making every other use of force criminal or rebellious by definition. It is both a description of how modern states slowly came to work and a rule the current international order treats as the baseline. Reading it as one historical arrangement rather than the natural order of things reframes its erosion: not a slide into chaos but the return of older repertoires the state once displaced.
The principle that the state alone holds the legitimate use of organised violence inside its territory — the constitutional premise of the modern international order, formulated by Max Weber in 1919 and conventionally tied to the 1648 Peace of Westphalia. The claim is descriptive of a historical period (roughly 1648–1991) and prescriptive of a normative order (the United Nations system) at the same time.
Etymology§
Westphalian refers to the 1648 Peace of Westphalia, the treaty cluster that ended the Thirty Years' War and is conventionally read as inaugurating the European inter-state system of equal sovereign territorial states. Monopoly on legitimate violence is Weber's formulation in Politik als Beruf (1919): "der Staat ist diejenige menschliche Gemeinschaft, welche innerhalb eines bestimmten Gebietes das Monopol legitimer physischer Gewaltsamkeit für sich (mit Erfolg) beansprucht."
The Westphalian monopoly is the constitutional fiction that the modern state rests on. The state — and only the state — gets to use organised violence in its territory, or to authorise others to do so; all other use of force is by definition illegitimate, criminal, or rebellious. The fiction is descriptive in that the post-1648 European system slowly approximated this condition over two and a half centuries of state-building, and prescriptive in that the post-1945 United Nations order treats the principle as a baseline against which deviations are scandalous.
The historical reality has always been messier than the fiction. The European powers built their states partly through chartered private violence — the letters of marque that licensed privateers, the chartered trading companies that ran their own armies, the frontier hosts that defended steppe borders in exchange for self-government. The state's monopoly came into being gradually and incompletely, and it never extended cleanly to the overseas empires, where chartered private operators held on longer.
The dissolution of the monopoly is the territory the chartered-violence corpus is mapping. Sean McFate's argument is that we are not heading toward state failure as a deviation from the norm but toward a neomedieval order in which the state's claim to sole legitimate violence is increasingly shared with private military companies, NGOs, criminal networks, and other non-state actors — a condition that looks abnormal against the Westphalian baseline but normal against the longer historical record. Mary Kaldor's new wars thesis (see new wars) describes the empirical landscape where this dissolution is most visible.
For this corpus the operative move is to read the Westphalian monopoly as a specific historical configuration rather than as the default condition of political life. Its erosion is not a return to chaos; it is a return to one of the older institutional repertoires the state replaced. Naming the configuration helps avoid the common rhetorical trick of treating its dissolution as unprecedented when in fact it is the previous arrangement reasserting itself.
