(a) (i) Jallianwalabagh.
(ii) Amritsar.
(iii) Non-cooperation movement.
(b)
(1) Violent Incident : The Movement was suspended by Gandhiji due to the ugly incident which took place in Chauri Chaura village of Uttar Pradesh in which 22 policemen were burnt alive by a mob. Gandhiji took a serious view of this incident. He felt that the nationalist workers had not yet properly understood the philosophy of non-violence. Non-violence was creed to Gandhiji who could hardly tolerate that his followers should indulge in violence. So he took the step of suspending the movement. (2) In 1922, there was a revolution in Turkey. Turkey became a republic, so after the revolution the movement lost its importance.
(c) (i) Establishment of New Educational Institutions : The Non-Cooperation Movement gave a boost to the Indian Education System. A new programme of national education was started. Institutions such as the Jama Millia and the Kashi Vidyapeeth were established.
(ii) Mass Movement : The Movement gave rise to the sentiments of nationalism on a wider scale. When thousands and thousands of people walked together shoulder to shoulder and resisted the British for months, the National Movement naturally became quite wider in its scope. It was no longer limited to only few educated urban people.
(iii) Unity : This was the first major Movement in which the Hindus and the Muslims participated as one, and scenes of ffatemality (friendly relations) were witnessed all over the country.
(iv) Change in the Character of the Congress : The Movement had a great impact on the working of the Congress. The Congress decided to use the weapons of Satyagraha and Non-Cooperation on wider scale.
