This paper explores the importance of Latin American social thought in the development of the Anglo-Saxon radical-Marxist current of thought in geography. Theories of dependence and underdevelopment are analyzed as sources of theoretical and political inspiration in the process of disciplinary renewal undertaken by young Anglo-Saxon geographers in the 1970s and early 1980s. Highlighting how such theories became central axes of analysis and study problems in radical geography within his studies on the geographical differentiation of global capitalism and his idea of uneven geographical development. In this way, the main works of David Harvey, Peter J. Taylor, Edward Soja, Richard Peet and David Slater are reviewed to show the importance of the notions of dependence, underdevelopment and unequal exchange when defining the geographical character of capitalism.
