Explanation:

Non-cooperation movement was started by Mahatma Gandhi in 1920 to drive the British out of the country.
Non-cooperation movement was nothing but a declaration of peaceful; and non-violent war against the atrocities of the British government which had gone back on its words.
The Non-cooperation Movement meant active refusal to abide by the laws and regulations passed by the government.
•An appeal was made to all the Indians to surrender their titles and to boycott the law courts, the educational institutions and the election of the legislatures.
•It was thought in the beginning that this would be enough to emphasis upon the government the need for greater reforms and more amenities in the administration of the country.
•However, it was planned that, in case, it did not succeed in bringing down the Government; the payment of taxes would be refused.
The Congress also declared that it would not be satisfied with anything less than Swarajya. Thus, for the first time the Congress had taken a revolutionary step. An organization which was wedded to constitutional means had now adopted a revolutionary policy and was even ready to work for a self rule disconnecting all relations from the government of England in case it was not granted by them willingly.
