Comparative constitutional studies has not digested globalization and the emergence of a multipolar world. To do so, I argue here, would require a far more serious engagement with Southern experiences of constitutionalism, including colonial legacies and a past that lingers on in legal doctrine, conceptual vocabulary, methodology and institutional structures. Such a Southern turn is not only about the South but equally about the North and the entanglement of North and South. In fact, colonial legacies are equally relevant but much less understood in the North. The Southern turn is hence a double turn: to the South and then to the North and the world.
