At the Calcutta session in Sep. 1920, the Congress resolved in favour of the Non-cooperation Movement and defined Swaraj as its ultimate aim (according to Gandhi).
The movement envisaged:
(i) Surrender of titles and honorary offices and resignation from nominated offices;
(ii) Refusal to attend government darbars and official functions and boycott of British courts by the lawyers;
(iii) Refusal of general public to offer themselves for military and other government jobs, and boycott of foreign goods etc.
Gandhiji, along with the Ali Brothers (of Khilafat Movement fame) undertook a nationwide tour addressing meetings. The educational boycott was specially successful in Bengal with Punjab too, responding under the leadership of Lala Lajpat Rai. Apart from educational boycott, there was boycott of law courts which saw major lawyers like Motilal Nehru, C.R. Das, C. Rajagopalachari, Saifuddin Kitchlu, Vallabh Bhai Patel, Aruna Asaf Ali, etc. giving up their lucrative practices in their fields. The non-cooperation movement also saw picketings of shops selling foreign cloth and boycott of the foreign cloth by the followers of Gandhiji. Another dramatic event during this period was the visit of the prince of Wales. The day he landed in India (in Bombay on Nov. 17, 1921) he was greeted with empty streets and downed shutters wherever he went.
The attack on a local police station by angry peasants at Chauri-Chaura, in Gorakhpur district of UP, on Feb. 5, 1922, changed the whole situation. Gandhi, shocked by Chauri-Chaura incident, withdrew the Non-Cooperation Movement on Feb. 12, 1922.
