This article critically reconsiders the conventional distinction between developed and developing countries. It argues that this binary classification is no longer analytically adequate, as it obscures historical responsibility, ignores colonial legacies, and presents hierarchical global relations as natural and neutral. The article draws on a postcolonial approach, which makes it possible to view development not as a universal and linear model, but as a historically and politically conditioned discourse. It emphasizes the need to construct new conceptual frameworks based on historical justice, epistemic plurality, and economic sovereignty. The article concludes that only a reconsideration of the underlying assumptions of development can open the way to imagining a more just global order that does not reproduce the logic of colonial domination under the guise of development.
