M. C. Chagla was born in Bombay in 1900. As a young boy he read Morley's Life of Gladstone and had the ambition to go to Oxford and join Christ Church college as Gladstone had done. In 1919, when Chagla went to Britain, he did not gain admission to Christ Church college, but did at Lincoln College. Here, Chagla read Modern History, with the intention to foster a public career.
Chagla had a very active social life as a student. He joined the Oxford Union and was elected to the Library Committee in 1921. He was a member of the Oxford Liberal Club, the Oxford Labour Club and Lotus Club. He was an active member of the Oxford Majlis and was elected President in June 1921. Chagla was also heavily involved with the Annual Indian Social Conference, that had begun in 1917 and would meet each year in Derbyshire for lectures, debates, games, and excursions.
Whilst studying at Oxford, Chagla also studied for the Bar as a member of Inner Temple. Having earnt a second class degree, and having been called to the Bar, Chagla returned to India in 1922. He joined the Bombay Bar where Jinnah was practising and joined the Muslim League soon after. However, Chagla broke off from the Muslim League when Jinnah began to espouse the two-nation theory. Chagla practised at the Bar from 1922 to 1941 and also taught law at Government College, Bombay. On Indian independence (15 August 1947), Chagla was appointed Chief Justice of Bombay. In 1958, Nehru appointed Chagla as Ambassador to the United States, and then High Commissioner in London in 1961. Chagla was Education Minister and then Minister of External Affairs in India, 1963-7.
