The Congress Medical Mission to Malaya was the last Indian non-state relief initiative that was sent abroad to provide humanitarian aid during late colonial rule and in the early postcolonial years. Whereas South Asian humanitarian initiatives had provided comprehensive aid for Indian and Allied soldiers at various fronts during the world wars and had given assistance to war victims in China and Malaya, the summer of 1946 became a turning point for their work when in mid-August, Calcutta was ravaged by the communal violence that broke out between Hindus and Muslims. Trapped in the riotous city for a few days was Dr C. Siva Rama Sastry, who was part of the Congress Medical Mission that had just returned from Malaya. When Sastry was finally able to return home to south India, he had to leave all his belongings behind.

After the so-called Great Calcutta Killings, the violence spread throughout British India, leading to riots and massacres in East Bengal, Bihar, Bombay, the United Provinces, Punjab and in other places before reaching its climax with partition. The end of colonial rule with the formation of two new nation states, India and Pakistan, in August 1947, was accompanied by large-scale violence that may have caused up to 1 million deaths and led to the displacement of approximately 12 million people.3 The unfolding humanitarian catastrophe in South Asia, however, did evoke a mixed international response. Several non-state humanitarian organisations from around the globe forwarded aid in cash and kind; some also sent relief workers to South Asia or already had volunteers on-site.
