Civil disobedience

The National Assembly was scheduled to meet in Dhaka on 3 March 1971. President Yahya Khan indefinitely postponed the assembly's first sitting, which triggered an uprising in East Pakistan. The cities of Dhaka, Chittagong, Rajshahi, Rangpur, and Khulna were engulfed with protests. Amid signs of an impending crackdown, Mujib addressed the people of East Pakistan on 7 March 1971 at the Ramna Race Course Maidan. In his speech, Mujib laid out the political history of Pakistan since partition and told the crowd that "e gave blood in 1952; we won a mandate in 1954; but we were still not allowed to take up the reins of this country". While Mujib stopped short of declaring outright independence, he stated that the goal of the Awami League from then on would be eventual independence. He declared that the Awami League would collect taxes and form committees in every neighbourhood to organise resistance. He called on the people "to turn every house into a fortress". His most famous words from the speech were the following.

This time the struggle is for our liberation! This time the struggle is for our independence! (For more info, see: 7 March Speech of Bangabandhu)

Following the speech, 17 days of civil disobedience known as the non-cooperation movement took place across East Pakistan. The Awami League began to collect taxes while all monetary transfers to West Pakistan were suspended. East Pakistan came under the de facto control of the Awami League. On 23 March 1971, Bangladeshi flags were flown throughout East Pakistan on Pakistan's Republic Day as a show of resistance. The Awami League and the Pakistani military leadership continued negotiations over the transfer of power. However, West Pakistani troops were being flown into the eastern wing through PIA flights while arms were being unloaded from Pakistan Navy ships in Chittagong harbour. The Pakistani military was preparing for a crackdown.
