Jose Carlos Mariategui (1894-1930) is widely recognised across Latin America as one of the most important and innovative Marxist thinkers of the twentieth century. Yet his life and work are largely unknown to the English speaking world. In this gripping political biography - the first written in English - Mike Gonzalez introduces readers to the inspiring life and thought of the Peruvian socialist. As one of the first modern thinkers to discuss what Marxism has to offer, and to learn from, the struggles of Indigenous peoples, his ideas have an immediate relevance in the context of Standing Rock and other native-led fights challenging pipelines across North America.
