Major events on the timeline which will receive the most extensive commentary and annotation include Muratori’s 1749 publication and its European reception; Pedro Rodríguez de Campomanes’s several defenses of state expropriation of ecclesiastical mortmain properties on the grounds of the state’s better ability to manage them in service of the public happiness; and Voltaire’s defense of absolutism in the History of Peter the Great (1759). Before and after this heyday of eudaemonic enlightened absolutism we find “public happiness” more commonly associated with a constitutionalist monarchy overseeing a eudaemonic civil society, as in Fénélon’s Telemachus, Locke’s Essay Concerning Human Understanding, and Andrés Mendo’s Perfect Prince. After 1770, numerous French publications after around 1770 marshaled Muratori’s own arguments against absolutism, including those of François-Jean de Chastellux, confidant of George Washington, François-Joseph de L’Ange, socialist justice of the peace, and most famously Necker and Rousseau. In Spain, Gaspar Melchor de Jovellanos, the father of the constitution and national parliament, redefined public happiness as widespread access to civil liberties, education, and entrepreneurship, and was followed in this by the romantic nationalist Juan Pablo Forner, among others. Enlightened absolutism was above all a propaganda rhetoric, and a relatively short-lived one, rather than a reality. This poster therefore contributes important data as to its periodization and more generally to the lexical history of the Enlightenment.
