Abstract:
In this article we examine imperialism in South America through the examples of the incursions of Great Britain and Brazil into Argentina and Bolivia, respectively, with the consent of the United States. In both cases, the issue of oil exploitation is a motivation. In the first, the conflict is reignited almost thirty years after the war between the two countries and, in the second, the tensions have their roots in the 19th century, developing over time with the presence of Petrobrás in the neighboring country.

Keywords: Imperialism. Oil. Malvinas. Roboré.
