Response to the 1970 cyclone in 1971 War

The 1970 Bhola cyclone made landfall on the East Pakistan coastline during the evening of 12 November, around the same time as a local high tide, killing an estimated 300,000 to 500,000 people. Though the exact death toll is not known, it is considered the deadliest tropical cyclone on record. A week after the landfall, President Khan conceded that his government had made "slips" and "mistakes" in its handling of the relief efforts due to a lack of understanding of the magnitude of the disaster.

A statement released by eleven political leaders in East Pakistan ten days after the cyclone hit charged the government with "gross neglect, callous and utter indifference". They also accused the president of playing down the magnitude of the problem in news coverage. On 19 November, students held a march in Dhaka protesting the slowness of the government's response. Maulana Abdul Hamid Khan Bhashani addressed a rally of 50,000 people on 24 November, where he accused the president of inefficiency and demanded his resignation.

As the conflict between East and West Pakistan developed in March, the Dhaka offices of the two government organizations directly involved in relief efforts were closed for at least two weeks, first by a general strike and then by a ban on government work in East Pakistan by the Awami League. With this increase in tension, foreign personnel were evacuated over fears of violence. Relief work continued in the field, but long-term planning was curtailed. This conflict widened into the Bangladesh Liberation War in December and concluded with the creation of Bangladesh. This was one of the first times that a natural event helped trigger a civil war.
