Slum eradication has been a concern in South Asian cities since the colonial times. Legislation and policies are being framed both out of national desires and international strategies. However, very little is being studied on how these legislation and policies come into being, specifically geography’s influence in their formulation. The article analyses parliamentary debates from India (Rajya Sabha, 1953–2014), and outlines the process of historical, political, and institutional dominance of Delhi. It shows that the slum legislation and policies in India are formulated by abstracting cases from the Delhi slums. This knowledge hegemony of Delhi is discussed within the growing consideration towards urban theory’s southern shift, which puts the Southern cities (megacities) as underdogs. The paper argues that at a regional level, these megacities exert the same hegemony that the southern theory wants to avoid. The results argue towards broadening the southern theory and ordinary city discussions.
