About Edwin Montagu
Edwin Samuel Montagu PC (6 February 1879 – 15 November 1924) was a British Liberal politician who served as Secretary of State for India between 1917 and 1922. Montagu was a "radical" Liberal and the third practising Jew (after Sir Herbert Samuel and Sir Rufus Isaacs) to serve in the British cabinet. He was primarily responsible for the Montagu–Chelmsford Reforms which led to the Government of India Act 1919, committing the British to the eventual evolution of India towards dominion status. He was opposed by his cousin Herbert Samuel, a moderate Zionist, who became the first High Commissioner of the British Mandate of Palestine. When Hankey was promoted to the newly created post of Cabinet Secretary, he recommended Montagu as Minister for National Service, for which he was considered in December 1916 (the job was given in the end to Neville Chamberlain). Montagu was not initially part of Lloyd George's inner circle, when he became Prime Minister, but he remained in office until his resignation in March 1922. Montagu was a "radical" Liberal and the third practising Jew to serve in the British cabinet.
