But the kingly state did not truly triumph as a stable and powerful entity until constitutional centralization became a reality. The Peace of Westphalia, ending the Thirty Years' War, ratified this new political creation, uniting the legitimacy of the dynastic realm and the Italian administrative innovations of the Renaissance, with the permanence of a fixed and contiguous national population. Westphalia provided France—the first and most successful kingly state—with a period of domestic consolidation, and effectively ended the Habsburg drive for empire. Ironically, it also set the stage for the next constitutional form of the state, the territorial state, as if the triumph of one constitutional order somehow germinates the form that will ultimately vanquish it.
