Direct Action Day (16 August 1946) was the day the Muslim League decided to take "direct action" for a separate Muslim homeland after the British exit from India. Also known as the 1946 Calcutta Killings, it was a day of nationwide communal riots. It led to large-scale violence between Muslims and Hindus in the city of Calcutta (now known as Kolkata) in the Bengal province of British India. The day also marked the start of what is known as The Week of the Long Knives. While there is a certain degree of consensus on the magnitude of the killings (although no precise casualty figures are available), including their short-term consequences, controversy remains regarding the exact sequence of events, the various actors' responsibility and the long-term political consequences. Controversy still rages about the respective responsibilities of the two main communities, the Hindus and the Muslims, in addition to individual leaders' roles in the carnage.

Thus, the riots opened the way to a partition of Bengal between a Hindu-dominated Western Bengal including Calcutta and a Muslim-dominated Eastern Bengal (now Bangladesh). The All-India Muslim League and the Indian National Congress were the two largest political parties in the Constituent Assembly of India in the 1940s. The Muslim League had demanded since its 1940 Lahore Resolution for the Muslim-majority areas of India in the northwest and the east to be constituted as 'independent states'. The 1946 Cabinet Mission to India for planning of the transfer of power from the British Raj to the Indian leadership proposed a three-tier structure: a centre, groups of provinces and provinces. The "groups of provinces" were meant to accommodate the Muslim League's demand. Both the Muslim League and the Congress in principle accepted the Cabinet Mission's plan. However, the Muslim League suspected
