1950s In 1950, it is estimated that a further one million refugees crossed into West Bengal, particularly in the aftermath of
1950 Barisal riots and
Noakhali riots. The 1951
Census of India recorded that 27% of Kolkata's population was East Bengali refugees mainly Hindu Bengalis and they contributed the economic growth of Kolkata in various fields. Millions of Hindus particularly Bengali speaking from East Pakistan took refuge in India's various states, mainly West Bengal. A number estimated that around 0.32 million Hindus from East Pakistan migrated mainly to Kolkata and various rural areas and towns of West Bengal during 1947.
1960s Migration continued, primarily from East Pakistan to India, right up to the liberation of Bangladesh in 1971, both on an ongoing basis and with spikes during periods of particular communal unrest such as the
1964 East Pakistan riots and the 1965 India-Pakistan War, when it is estimated that 600,000 refugees left for India. This includes around 4.1 million coming between 1946 and 1958 and 1.2 million coming between 1959 and 1971.
1970s Another major influx into India came in 1971 during the
Bangladesh Liberation War, when Hindu refugees escaped systematic
mass killings,
rapes, lootings and arson. It is estimated that around ten million East Bengali refugees entered India during the early months of the war, of whom 1.5 million may have stayed back after Bangladesh became independent. == See also ==
