The Integral Humanism of Deendayal Upadhyaya, which was stated in four lectures in 1965, is a result of the Indian search for a political and economic philosophy based on their own intellectual framework. Its basic premises are human dignity, social responsibility, decentralization, self-reliance and the welfare of people left behind issues which are pertinent to current international politics as well as national development. This article looks into the potential of the international implications of Integral Humanism, employs qualitative conceptual analysis and also compares the Integral Humanism with the capability approach, Gandhian thought, critiques of market society and postcolonial scholarship. It then looks at the areas of resonance with the current Indian diplomacy such as strategic autonomy, South–South cooperation, human-centric globalization and climate cooperation. The article argues that the Integral Humanism approach can widen the perspectives of development discussions by questioning the economic narrow vision and by focusing on distribution, local agency and ecological responsibility. It is however not a theory of international relations nor is it a template for policy. It is impo rtant to assess the international relevance through critical translation, empirical tests, and compatibility with democratic accountability, equal citizenship, human rights and cultural pluralism. The article suggests a practical model of cooperation based on multiple welfare indicators, Antyodaya test, practicability of cooperatives self-reliance and transparent institutional review of technology sharing in a fair manner. This paper examines the question of whether India can become a developed nation without compromising its national sovereignty and strategic autonomy by drawing on the principles of Deendayal Upadhyaya's Integral Humanism. The paper looks into the possibility of India becoming a developed nation without sacrificing its national sovereignty and strategic autonomy and demonstrates that it is possible with the principles of Deendayal Upadhyaya's Integral Humanism.
