Sir Denzil Ibbetson

Sir Denzil Charles Jelf Ibbetson (30 August 1847 to 21 February 1908) was a British Indian Civil Service officer. He is in this record for two things: the Punjab census report of 1881, which set out how the Raj classified the province's peoples, and his term as Lieutenant-Governor in 1907, when the Punjab government put down the canal-colony agitation and deported two of its leaders.

Career. Born at Gainsborough in Lincolnshire, he was educated at St Peter's College, Adelaide, and St John's College, Cambridge, came third in the Indian Civil Service examination of 1868 and joined the Punjab commission at the end of 1870. He did settlement work in Karnal district and was Deputy Superintendent of the Punjab census of 1881. He compiled the Punjab Gazetteer, became Chief Commissioner of the Central Provinces in 1898, and later sat on the Viceroy's Council under Lord Curzon. He was made KCSI in 1903, acted as Lieutenant-Governor of the Punjab in 1905, and was confirmed in the post on 6 March 1907.

The census. His report on the 1881 census was published in 1883. Its chapter on the races, castes and tribes of the people was reprinted in Lahore in 1916, after his death, as Panjab Castes. In it he argued that caste was a social rather than a religious mechanism. On the Sikhs he wrote that Sikhism did much to weaken caste rules in the centre of the Punjab. The historian Crispin Bates has said his classification lacked a scientific basis.

1907. The Colonisation Bill of 1906, which enforced strict primogeniture in the canal colonies, and higher water charges brought Ajit Singh and Lala Lajpat Rai into a mass agitation in 1907. According to the Dictionary of National Biography, Ibbetson put down the disturbances at Lahore and Rawalpindi, deporting Lajpat Rai and Ajit Singh without trial. Lajpat Rai was deported to Mandalay on 9 May 1907. The Encyclopaedia of Sikhism says Ajit Singh was deported to Mandalay on 2 June 1907 on the Punjab government's recommendation, and that he was released in November 1907. The Tribune says both men were released after about six months, the authorities having found no solid proof against them.
