Question

Tell in brief about the session of Calcutta in September 1920

Answer 1

It was held in two place:
September 1920- Calcutta (Kolkata)

Answer 2

The Rowlatt Act, followed by the Jallianwallah Bagh massacre and the Khilafat issue embittered Gandhi's feelings towards the British government. Gandhi urged the Congress to launch a Non-Cooperation Movement on these three issues.

In September, 1920, a special session of the Congress, presided by Lala Lajpat Rai was convened at Calcutta to approve the scheme.

The Non-Cooperation resolution garnered mixed responses. Pt. Motilal Nahru and Anil Ali Brothers supported the resolution, whereas Mrs Annie Besant, Pt. Malaviya and Shri C. R Das vehemently opposed. They feared that large scale mass action against the British government would lead to violence on a wide scale, as occurred during Rowlatt satyagraha.

In December 1920, at the Nagpur Congress, the resolution on Non-Cooperation was repeated again. This session garnered greater support in favor of the resolution.
