The Indian States Committee was formed in 1927 and submitted its report in 1929 (often associated with 1928 due to its active inquiry period) under the chairmanship of Sir Harcourt Butler. Popularly known as the Butler Committee, it was established by the British Government to examine and clarify the relationship between the Paramount Power (the British Raj) and the various Princely States. The committee's primary objective was to investigate the nature of 'paramountcy' and the financial relations between British India and the states. While the Motilal Nehru Report of 1928 also addressed constitutional issues, it was a separate nationalist initiative. Sir Harcourt Butler's leadership was central to the committee's findings, which famously concluded that 'Paramountcy must remain paramount' to maintain the British link with the states.
