Around 1800, merchants, scientists and adventurers travelled to Latin America with different purposes. Their multifaceted interests in a world region, experiencing a threshold of independence from Spanish colonial rule, inspired new historical and political works about the continent’s recent past. The Enlightenment provided not only the philosophical armamentarium against corruption, but it also paved the way to a new expression of sentiments and to the loss of fear when addressing injustice. Some examples of these are Hipólito Villaroel’s list of grievances and Humboldt’s Political essay. These two authors provide some thoughts on the political landscape of New Spain (now Mexico), while the two Swiss physicians Rengger and Longchamp describe the ruthless and odd dictator Francia of independent Paraguay as a champion of anti-corruption. Finally, Argentine dictator Rosas—and his robberies as described by Rivera Indarte, Sarmiento and other anonymous authors—represent the embodiment of corruption through pure larceny, for whose crimes the Spanish colonial past apparently no longer served as a comparison.
