During the 1820s, Colombia's diplomats in London, Washington and Philadelphia worked hard to obtain diplomatic recognition for their nascent republic. Their efforts were also geared towards making Colombia attractive to European and North American settlers whose industry and work ethic would, they hoped, turn it into a civilised and modern Euro-Atlantic nation. The immigration schemes they promoted enable us to understand the type of nations the nation-makers of post-independence Spanish America envisioned and how, by appealing to sentiments of hemispheric solidarity – among other means – they sought to turn their visions into reality. A comparison with similar eighteenth-century schemes promoted by the Bourbons, moreover, reveals the persistence, albeit with some critical modifications, of late-colonial ways of thinking and envisioning society.
