A collaborative volume that reads the age of revolutions from the Mediterranean outward, tracing how ideas, exiles, capital and images moved between southern Europe and the Americas between the Seven Years' War and the 1860s. Its first section follows a Neapolitan route: Genovesi's imagined travels, the Enlightenment at Naples, Charles III between Spain and the Indies, the expelled Spanish Jesuits, and the long quarrel over the nature of the New World.

Later sections track revolutionary echoes across the ocean, constitutional experiments running from Cadiz to South America and the pull of English constitutional models within the Mediterranean, and finally the making of new nations, with republics and federations, caudillos and temporary dictatorships, Spanish and Italian exiles in London, and the slow passage out of slavery.

Geggus contributes a chapter on Saint-Domingue, whose fifteen-year upheaval he calls the most transformative of the period, and whose exports underwrote French Atlantic prosperity as far as Marseille.
