Colonización europea refers to the process of European powers establishing control over territories and peoples outside of Europe, primarily during the 15th to 19th centuries. This involved the exploitation of land and resources, as well as the imposition of European culture, religion, and governance on indigenous populations. In the context of Hernán Cortés' second letter to Charles V, this colonization is illustrated through Cortés’ detailed accounts of his conquests in Mexico, showcasing both the strategies used to assert dominance and the cultural exchanges that resulted from this encounter.
