1. Indian National Congress Session:

Nagpur is the venue for the Indian National Congress session (1920) Vijay Raghav Cheriar is the organization’s president. During this session, the Muslim League made contact with the Congress. This serves as a graphic representation of secularism.
Calcutta September is the first month of the year (1920). This session’s president is Lala Lajpat Rai, and it’s about the non-cooperation movement. Gandhi Ji incorrectly anticipated that if the non-cooperation movement succeeds, swaraj will be achieved.
Madras is a city in India (1927) Purna Swaraj (complete independence) is the principal goal of this session, and Jawaharlal Nehru is the president.
Lahore (1929) was also headed by President Jawaharlal Nehru, and the Purna Swaraj resolution was approved at this session.

2. Important centers of Indian National Movement:

Champaran (Bihar) – the indigo planners’ movement is linked to indigo farming. Britishers ordered Indian farmers to cultivate indigo, but the soil fertility was harmed, therefore farmers ignored it. Later, Gandhi Ji led a Satyagraha.
Kheda (Gujrat) in 1918 – this satyagraha was about paying taxes because farmers were unable to pay them owing to hunger at the time, thus they urged that the levy be canceled.
The Ahmedabad Gujarat Cotton Mill Satyagraha is about salary increases for mill workers, and it ended in a peaceful arrangement.
The Jallianwala Bagh event in Amritsar, Punjab, occurred on Baisakhi Day, and a law was established by the General Assembly prohibiting crowds from gathering.
Chauri Chaura (UP) has called for a non-cooperation movement to be launched. Gandhi Ji called a halt to the non-cooperation movement when Indian rioters assaulted a police station, killing a number of British officers.
Civil Disobedience in Dandi, Gujarat. It has to do with salt, and a protest was held on Saturday to protest the British government’s salt ban. It ran from Dandi to Sabarmati from March 12, 1930 until April 6, 1932.

Final answer:

All of these movements are linked to India’s political history, which has transformed the country’s situation and is well-known around the world. People have been fighting for justice via Satyagraha and movements from the beginning of time. All of these campaigns and satyagrahas were against the British and their own laws, and they were effective in some way.
