Latin America underwent significant changes from 1850 to 1880. Positivism and modernization theories shaped governments, emphasizing science and progress. This period saw the rise of liberal constitutions, economic shifts towards export-oriented economies, and rapid urbanization. The era was marked by political consolidation, expansion of infrastructure, and cultural transformations. While these changes brought economic growth and technological advancements, they also perpetuated social inequalities and increased dependence on foreign markets, setting the stage for future developments.
