The South Asian region consisting of India, Pakistan, Bangladesh, Nepal, and Sri Lanka share a common history of British colonial rule for nearly 200 years. Most of these countries gained independence during the 1940s. Western European ideas of social medicine found considerable resonance. However, through the process of anti-colonial struggle, new ideas on the relationship between society, medicine, and health were brought to light by actors such as practitioners of indigenous systems of medicine, leadership of the nationalist movement, the communist movement, and radical elements within the medical community and society. This chapter explores the engagement of diverse sets of actors from differing ideological positions that engaged in the relationship between society and health in the Indian subcontinent. It further seeks to explore how the Non-Aligned Movement created by postcolonial societies provided a platform for South–South networks in the economy and social sectors to define inclusive development. In medicine and health, there were efforts to redress inequalities through various reform initiatives that had local importance and influenced global health policies.
