This article explores one of the main arenas in which change came over the role of the monarchy as part of Europe's transition to a modern political system: diplomacy. Traditionally, there had been a dual aspect to monarchy that merged dynastic and state interests. The creation of modern constitutional political systems in the nineteenth century forced European crowns to modify their prerogatives and effective power, sharing this with elected politicians. This included foreign policy, which thenceforward pursued national interests that did not always agree with dynastic ones. Focusing on the Spanish branch of the house of Bourbon, I examine this involved and controversial process. Firstly, I trace the breaking of the Bourbon alliance which had been dominant in the eighteenth century and its unsettled reconfiguration into the worldwide system created by the Congress of Vienna. I then discuss the complex imposition of the nation-state interest over the dynastic one in a time of deep ideological division – between constitutional and absolutist systems – and traumatic revolutions that overthrew Bourbon monarchs. From the mid-nineteenth century onwards, the liberal and nationalist wave forced transnational family ties to succumb to national interest.
