Swaraj Party was an Indian political party established in late 1922–early 1923 by members of the Indian National Congress (Congress Party), notably Motilal Nehru and CR Das. Their first session was held at the residence of Motilal Nehru in Allahabad. They were among the pro changes who wanted to contest in the elections. Many candidates of the Swaraj Party got elected to the central legislative assembly and provincial legislative council in the 1923 elections where they opposed the unjust government policies.
