Building on recent literature on the history of political economy and Spanish imperial history, the article reconstructs the ideas that supported the colonial development of the meat industry in the Río de la Plata. Archival and printed sources are employed to illustrate the different arguments revolving around colonial economic development and imperial rule, in the words and practices of merchants, explorers, administrators and ministers. This way, it is possible to disclose the multiple imperial visions circulating in the Spanish Atlantic. The (...) analysis suggests that economic reformism was not only a European intellectual and political movement but was shared and appropriated by Spanish Americans. They employed arguments in political economy to foster their agenda, namely the economic improvement of their territory in the broader context of the Spanish commercial empire.
