Named as the India Secretary for the Lloyd George ministry, Edwin Samuel Montagu made the "Grand Declaration" on 20 August 1917 that British policy would henceforth be "increasing association of Indians in every branch of the administration and the gradual development of self-governing institutions". Montagu and Viscount Chelmsford, the Governor-General of India, then made an extensive tour of the subcontinent in 1917 and 1918. The Montague–Chelmsford Report's recommendations formed the basis for the Government of India Act 1919 that established "diarchy" in British India.
