different from other documents of the period. Yet the mechanisms through which they were to be reached were unprecedented. The war had shattered pretensions to universality or confessional solidarity. Begun as a struggle of Catholics against Protestants, particularly after France’s entry against the Catholic Holy Roman Empire it had turned into a free-for-all of shifting and conflicting alliances. Much like the Middle Eastern conflagrations of our own period, sectarian alignments were invoked for solidarityand motivation in battle but were just as often discarded, trumped by clashes of geopolitical interests or simply the ambitions of outsized personalities. Every party had been abandoned at some point during the war by its “natural” allies; none signed the documents under the illusion that it was doing anything but advancing its own interests and prestige.
Paradoxically, this general exhaustion and cynicism allowed the participants to transform the practical means of ending a particular war into general concepts of world order. With dozens of battle-hardened parties meeting to secure hard-won gains, old forms of hierarchical deference were quietly discarded. The inherent equality of sovereign states, regardless of their power or domestic system, was instituted. Newly arrived powers, such as Sweden and the Dutch Republic, were granted protocol treatment equal to that of established great powers like France and Austria. All kings were referred to as “majesty” and all ambassadors “excellency.” This novel concept was carried so far that the delegations, demanding absolute equality, devised a process of entering the sites of negotiations through individual doors, requiring the construction of many entrances, and advancing to their seats at equal speed so that none would suffer the ignominy of waiting for the other to arrive at his convenience.
The Peace of Westphalia became a turning point in the history of nations because the elements it set in place were as uncomplicated as they were sweeping. The state, not the empire, dynasty, or religious confession, was affirmed as the building block of European order. The concept of state sovereignty was established. The right of each signatory to choose its own domestic structure and religious orientation free from intervention was affirmed, while novel clauses ensured that minority sects could practice their faith in peace and be free from the prospect of forced conversion. Beyond the immediate demands of the moment, the principles of a system of “international relations” were taking shape, motivated by the common desire to avoida recurrence of total war on the Continent. Diplomatic exchanges, including the stationing of resident representatives in the capitals of fellow states (a practice followed before then generally only by Venetians), were designed to regulate relations and promote the arts of peace. The parties envisioned future conferences and consultations on the Westphalian model as forums for settling disputes before they led to conflict. International law, developed by traveling scholar-advisors such as Hugo de Groot (Grotius) during the war, was treated as an expandable body of agreed doctrine aimed at the cultivation of harmony, with the Westphalian treaties themselves at its heart.
The genius of this system, and the reason it spread across the world, was that its provisions were procedural, not substantive. If a state would accept these basic requirements, it could be recognized as an international citizen able to maintain its own culture, politics, religion, and internal policies, shielded by the international system from outside intervention. The ideal of imperial or religious unity—the operating premise of Europe’s and most other regions’ historical orders—had implied that in theory only one center of power could be fully legitimate. The Westphalian concept took multiplicity as its starting point and drew a variety of multiple societies, each
