<P> The Non-cooperation movement was a reaction to the oppressive policies of the British Indian government such as the Rowlatt Act and the Jallianwala Bagh massacre . A meeting of civilians held at Jallianwala Bagh near the Golden Temple in Amritsar was fired upon by soldiers under the command of Brigadier - General Reginald Dyer, killing and injuring thousands of protestors . The outcry generated by the massacre led to thousands of unrests and more deaths at the hands of the police . The massacre became the most infamous event of British rule in India . </P> <P> Gandhi was horrified . He lost all faith in the goodness of the British government and declared that it would be a "sin" to cooperate with the "satanic" government . </P> <P> Indian Muslims who had participated in the Khilafat movement to restore the status of the Caliph gave their support to the non-cooperation movement . In response to the Jallianwala Bagh Massacre and other violence in Punjab, the movement sought to secure Swaraj, independence for India . Gandhi promised Swaraj in one year if his Non-Cooperation programme was fully implemented . The other reason to start the non-cooperation movement was that Gandhi lost faith in constitutional methods and turned from cooperator of British rule to non-cooperator . </P> <P> Other causes include economic hardships to the common man, which the nationalists attributed to the flow of Indian wealth to Britain, the ruin of Indian artisans due to British factory - made goods replacing handmade goods, and resentment with the British government over Indian soldiers dying in World War I while fighting as part of the British Army . </P>
