Non-cooperation movement
The first big national involvement of Nehru came at the onset of the Non-cooperation movement in 1920. He led the movement in the United Provinces (now Uttar Pradesh). Nehru was arrested on charges of anti-governmental activities in 1921, and was released a few months later. In the rift that formed within the Congress following the sudden closure of the Non-Cooperation movement after the Chauri Chaura incident, Nehru remained loyal to Gandhi and did not join the Swaraj Party formed by his father Motilal Nehru and CR Das. In 1923, Nehru suffered imprisonment in Nabha, a princely state, when he went there to see the struggle that was being waged by the Sikhs against the corrupt Mahants.
