Peace of Utrecht
The 1713 treaties ending the War of the Spanish Succession, the first European settlement to make the balance of power an explicit goal.
The Peace of Utrecht was the cluster of treaties, signed between 1713 and 1715 in the Dutch city of Utrecht, that ended the War of the Spanish Succession and, for the first time, wrote the 'balance of power' into a European settlement as a stated goal. The war had begun in 1701, when the childless Charles II of Spain willed his entire empire to a grandson of Louis XIV of France, raising the specter of a single Bourbon colossus astride France, Spain, and their overseas possessions. A grand alliance of Britain, the Dutch Republic, and Austria fought for more than a decade to stop it. Years of allied victories under the Duke of Marlborough and Prince Eugene, at Blenheim, Ramillies, and Oudenarde, bled France without breaking it, and exhaustion on every side finally forced terms. Utrecht was the compromise that let everyone put down their arms.
The settlement
The central bargain was elegant. Philip V, Louis XIV's grandson, kept the Spanish throne and its vast empire, but he and his descendants formally renounced any claim to the crown of France. The two kingdoms might share a dynasty; they could never share a king. The union that had frightened Europe was ruled out by law. Around that pivot the map was rearranged: Austria took the Spanish Netherlands (modern Belgium) along with Naples, Sardinia, and Milan; the Duke of Savoy received Sicily and a royal title; and the Dutch won a line of 'barrier fortresses' against any future French advance. A parallel treaty at Rastatt in 1714 settled Austria's separate peace with France.
Britain's victory
The quiet winner was Britain, whose Tory ministry had negotiated a separate peace behind its allies' backs. From Spain it took Gibraltar and Minorca, commanding the mouth of the Mediterranean; from France it gained Newfoundland, Nova Scotia, and the Hudson Bay territory. France also recognized the Protestant Hanoverian succession to the British throne and agreed to expel the exiled Stuart pretender. And Britain secured the asiento, the coveted contract to supply enslaved Africans to Spanish America for thirty years, a license that fed both British commerce and the Atlantic slave trade. Britain left Utrecht as the offshore power that profited from the continent's quarrels without being trapped inside them.
Balance made a principle
What makes Utrecht a landmark is not its map but its logic. The Anglo-Spanish treaty spoke openly of preserving the 'balance of power,' so that peace might rest on a just equilibrium in which no single state could dominate the rest. Earlier settlements had restored a rough equilibrium in practice; Utrecht was the first to name it as the object of the peace, a thing to be deliberately preserved rather than an accident to be endured. This was the states-system born at the Peace of Westphalia in 1648 reaching maturity: sovereignty was now to be managed deliberately, the strong checked by coalitions and compensations rather than by any higher authority. For the next century Britain would style itself the balancer, throwing its weight against whichever power, Bourbon France and then Napoleon, reached for mastery of Europe.
The principle Utrecht set down outlived every border it drew. When the statesmen at Vienna in 1815 and at Versailles in 1919 argued over how to stop any one power from dominating the continent, they were still speaking the language first written into a treaty at Utrecht in 1713.
