William Henry Sleeman
Sir William Henry Sleeman (8 August 1788 – 10 February 1856) was a British officer and administrator in Company-ruled India, best known for his leading role in the Anti-Thuggee Campaign of the 1830s against what he represented as a pan-Indian fraternity of ritual stranglers. Sleeman served as General Superintendent of the Thuggee Department from 1835 to 1855 and published his main work on thuggee, entitled Ramaseeana, in 1836. His writings served as the foundation for the colonial-era representation of thuggee and formed the basis of Philip Meadows Taylor's 1839 novel Confessions of a Thug.

Biography
Biography
Sleeman joined the Bengal Army of the East India Company in 1809 and served during the Gorkha War from 1814 to 1816. He joined the Company's political service in 1820 as an assistant to the Agent of the Governor-General in the Saugor and Nerbudda Territories, remaining in central India for the Anti-Thuggee Campaign. Sleeman's work saw the extension of policing powers over itinerant communities, which later culminated in the 1871 Criminal Tribes Act. Between 1843 and 1849, Sleeman served as the British Resident in Gwalior, and from 1849 to 1854 in Lucknow. He toured the Kingdom of Oudh in 1849–1850, and his subsequent report to Governor-General Lord Dalhousie (published in 1858 as A Journey Through the Kingdom of Oude) proved instrumental in justifying its annexation in 1856. Sleeman's health collapsed in 1854 and he died at sea in 1856, en route to London. Sleeman himself strongly argued against the annexation of the native states, cautioning Lord Dalhousie that it could lead the Company's sepoys to mutiny. His correspondence on the matter was published posthumously in The Times in 1857 and together with his 1849–1850 report in 1858. Sleeman also published works on political economy in which he criticised the Company's high taxes and lack of investment in the local population, viewing the policies as detrimental to British rule. He inadvertently made the first discovery of dinosaur bones on the Indian subcontinent in 1828, proposed in 1877 as Titanosaurus indicus, and his reports on feral children raised by wolves are thought to have inspired the character of Mowgli in Rudyard Kipling's 1894 novel The Jungle Book.

Early life and education
Early life and education
William Henry Sleeman was born on 8 August 1788 in Stratton, into a Cornish gentry family. His parents were Philip Sleeman, who worked at H.M. Excise, and Mary (d. 1818), née Spry. The family moved to Bideford in 1798 for Philip's work but moved back to Cornwall after Sleeman's father died in 1802, leaving the family with financial difficulties. This prevented Sleeman from becoming an officer in the British Army, which effectively required a sufficient private income, and he instead settled on joining the East India Company. With the help of family connections and the offices of Lord de Dunstanville, Sleeman was accepted into the Bengal Army of the Company as a cadet. In March 1809, he embarked on the Devonshire from Gravesend, arriving in Calcutta in late 1809.
Military career
Military career
In December, Sleeman began his cadetship in Dinapore and was promoted to the rank of ensign in 1810. He was promoted to lieutenant in December 1814 and served in the Gorkha War from 1814 to 1816. Inbetween the 1814 and 1815 campaigns, the 12thNative Infantry Regiment in which Sleeman served was devastated by an outbreak of malaria. Of the regiment's ten European officers, seven fell ill, with Sleeman among the two that survived. After the war, he was stationed at Allahabad in 1817 and in 1818 at the cantonment of Pratapgarh in the Oudh State. With little prospect of further active service, Sleeman applied to join the Company's political service.
Civil and political service
Civil and political service
In 1820, Sleeman assumed the position of junior assistant to the Agent of the Governor-General in the Saugor and Nerbudda Territories. In 1822, he was placed in charge of the Narsinghpur District. He was forced to take a period of sick leave in 1826 and was placed in charge of the Jubbulpore district in 1828. On 21 June 1829, Sleeman married Amélie Josephine de Fontenne who was the daughter of Count Blondin de Fontenne, a French nobleman that had escaped the Revolution. In his 1844 book Rambles and Recollections of an Indian Official, Sleeman recounted his involvement with a case of sati in the village of Gopalpur in November 1829, in which a recently bereaved widow convinced him that her wish was to burn with her husband's body.
Localised efforts (1829–1830)
Localised efforts (1829–1830)
The British colonial authorities became aware of bands of highway robbers they termed Thugs in 1807–1809, and by 1815 thuggee had been accepted by British officials as specialised and organised crime with the Thugs given a caste-like status. In 1830, Sleeman began assigning approvers (the period term for informants) that he had in captivity to accompany armed patrols along exposed roads, capturing 24 Thugs on two occasions and acquiring more approvers in the process. Though the historian Mike Dash notes that Sleeman had been in India in 1810 when a warning was sent out to the Company's sepoys and was likely to have been aware of a thuggee case in Jubbulpore in 1826, he states that there is no evidence to suggest that Sleeman took a great interest in the matter before 1829. Dash surmises that Sleeman became interested in thuggee in 1829, in the context of Captain Borthwick's success in arresting Thugs and his slow career progression by that point after ten years of service. Sleeman submitted his first report on thuggee in May 1830, writing: • Illustration — The beginning of the October 1830 letter, reprinted in 1832 Sleeman further asserted that the Thugs could murder freely in Bhilsa and suggested that the district be secured from Scindia rule. Francis Curwen Smith, Sleeman's superior as Agent of the Saugor and Nerbudda Territories, suggested him for the position of Agent at Saugor in September. That year, Sleeman was sent 72 Thugs for trial that had been arrested in 1822 by Commissioner C. A. Molony, but which had been forgotten about after Molony had died. Sleeman argued against capital punishment for the Thugs on the basis that they had already been detained for eight years, during which time 33 of them had died. Smith and the Government disagreed, and 26 were sentenced to be hanged. On 3 October, Sleeman contributed an anonymous letter to the Calcutta Literary Gazette that recounted the execution of 11 Thugs and asserted that all the Thugs in India congregated at Vindhyachal Temple in Mirzapur, where their expeditions were planned by the temple priests. Sleeman's letter further provided details of ceremonies performed by the Thugs and described Thuggee as:
Centralised campaign (1830–1839)
Centralised campaign (1830–1839)
Sleeman's anonymous letter resonated with the Government, prompting Chief Secretary to the Government George Swinton to commission a report from Smith and Sleeman on the feasibility of a wider campaign against thuggee. Swinton appointed Sleeman Agent at Saugor on 13 October and Smith submitted the plan on 19 November, which argued for the establishment of a Superintendent for the Suppression of Thugs that would try Thugs in the Saugor and Nerbudda Territories. Smith argued that Sleeman should be appointed to the office based on his "extensive acquaintance with the habits, haunts, and customs of the Thugs and Phansigars". Governor-General Lord William Bentinck declined to establish a specific office for thuggee, though provided Sleeman with 50 barkandazes (mercenaries) to pursue and apprehend the gangs. Sleeman was appointed Superintendent of the operations, while Smith oversaw the trials, whereby approvers were sent out with troop detachments to disinter the bodies and point out their former associates. Accounts and depositions from Thugs captured around this time would form the basis of Sleeman's writings on thuggee, with the gang leader Feringheea captured by a nujeeb patrol escorted by approvers in November. Sleeman organised a system of investigation, prosecution, and punishment and institutionalised the use of approvers. To secure approver testimony, he played different factions within the gangs off of one another. Thugs were thereafter convicted based on circumstantial evidence and approver testimony in the Saugor and Nerbudda Territories, which had been established in 1818 outside the scope of the Company's usual regulations. • Illustration — Title page of Ramaseeana On 5 March 1835, Sleeman was made General Superintendent of the newly established Thuggee Department after Smith declined the post. Sleeman's worsening health forced him to take a period of sick leave in 1835, departing for the Himalayas. He later published his writings made during the November 1835–early 1836 journey in 1844 as Rambles and Recollections of an Indian Official. Sleeman published his main work on thuggee in 1836 entitled Ramaseeana, named after the Thugs' criminal argot 'Ramasee' that he perceived to be the key to uncovering the secrets of thuggee. In it he compiled a vocabulary of Ramasee from conversations with more than a dozen approvers, also printing some of them alongside approver testimony, and published genealogical trees derived from a 1797 Gwalior State tax list of Thugs. During these interviews, Sleeman and his colleague Captain James Paton were predominantly interested in the goddess-worship of the Thugs, their observance of rules and omens, and the variance between different gangs' customs. In the opening lines to Ramaseeana, Sleeman stated: "I am satisfied that there is no term, no rite, no ceremony, no opinion, no omen or usage that they have intentionally concealed from me". Upon discovering 'river-thugs' operating on the Ganges whose modus operandi left very little circumstantial evidence, Sleeman successfully lobbied for the passage of Act III of 1836 that made simply belonging to a thuggee gang a crime punishable by life imprisonment with hard labour. In March, he recommended that a manufactory be established or found to accommodate the approvers, whereafter the Jubbulpore School of Industry was founded later that year. In a February 1838 letter to his friend Charles Fraser, who had replaced Smith as magistrate of Jubbulpore, Sleeman described their duties as paramount to the interests of humanity and declared: "Believe me Fraser, I would not exchange the share I have had in this work for the most splendid military service that man ever performed in India. I glory in it and ever shall do." Dacoity was added to Sleeman's responsibilities that same year as thuggee activity had been effectively suppressed and in 1839 he coined the term Megpunnaism to refer to the murder of impoverished parents to attain their children for sale, portraying it as a new form of thuggee. Sleeman initially welcomed his assistants' work in early 1838 arresting bands of religious mendicants, asserting in February that he now had full proof that Gosains and Bairagis were "assassins by profession". However, Sleeman halted the proceedings a couple of months later after the failure of trials against bands of Thoris and Jogis, remarking that had a further case against Jogis gone ahead the evidence was such that "it would have created a feeling of distrust in all that we do which nothing could ever have removed". Sleeman reminded his officers in April 1838 that if they were morally satisfied that the prisoner had belonged to a gang of Thugs but there was not enough evidence to convict them, then it was their duty to detain them indefinitely under Regulation VIII of 1818. In 1839, Sleeman declared that thuggee had been effectively destroyed as an organisation, marking the end of the campaign. During this period, Sleeman also published works on political economy in which he criticised the economic philosophy of the Company, based on the ideas of utilitarian economists such as David Ricardo, Thomas Malthus, James Mill, Jean-Baptiste Say, and John Ramsay McCulloch. With a view to strengthening British rule, he objected to the accumulation and concentration of wealth in the hands of the Company, perceiving the policies to be undermining law and order. He criticised the Company's economic policy, rooted in the Ricardian theory of rent, for prioritising what he termed "tribute" over expenditure, on the basis that it led to spiralling demand and ultimately an inability to pay into the Company's revenues.

Later career
• Illustration — 1851 portrait of Sleeman by George Duncan Beechey In 1842, Sleeman was sent to Bundelkhand to investigate a rebellion under two Bundela landlords, assuming the role of Agent in Bundelkhand. Amid a challenge against the British-backed successor to Maharaja Jankoji Rao Scindia II, Sleeman was appointed Resident at Gwalior in 1843. In the midst of negotiations in December, he counselled Governor-General Lord Ellenborough that marching troops into Gwalior territory would lead to a confrontation. By 1845, and if the Gwalior State is included, Sleeman was responsible for over sqmi of Indian territory. Sleeman assumed the position of Resident at Lucknow on 11 January 1849, where he was described by the Delhi Gazette in February as being "probably the only British official ever to have addressed the King of Oudh in correct Urdu and Persian". In an 1848 letter to Governor-General Lord Dalhousie, Sleeman argued against the annexation of native states, writing: Sleeman's 1849 Report on Budhuk alias Bagree Decoits set out a methodology for the identification and classification of criminal communities, in which he claimed that Budhuks were a pan-Indian cabal under several aliases (which were in reality different jātis). Sleeman toured the Kingdom of Oudh from November 1849 to February 1850, reporting his findings to Lord Dalhousie. In his report, he made clear that Nawab Wajid Ali Shah was an incapable ruler, surrounded by equally incapable administrators, and detailed rampant corruption and exploitation. In his 1852 correspondence with Dalhousie, Sleeman described the King as a "crazy imbecile", stating that the people "want our government". While his characterisation of Oudh's administration proved instrumental in justifying the later annexation of the kingdom, Sleeman himself strongly argued against it, stating in his correspondence to Company chairman Sir James Hogg in 1852–1853: Sleeman favoured the imposition of a British-directed Board composed of members of the Lucknow aristocracy to administrate Oudh in perpetuity or until the heir apparent came of age, upon which they would be bound to govern in accordance with the advice of the British Resident. Historians have since contested Sleeman's characterisation of Wajid Ali Shah and his administration, arguing that his report was based on accounts by people aiming to discredit the King and contained inconsistencies, or that his sympathies with the local population led him to exaggerate the extent of the misrule. Sleeman further asserted to Hogg that the Government had no right to annex the princely states and that these measures were driven by "a school... characterised by an impatience at the existence of any native state." There are several accounts of attempts on Sleeman's life across his career, including one in Jhansi in 1842 by a dismissed sepoy, an attempt in November 1851 that was allegedly instigated by the Nawab's Munshi, a bed-stabbing attempt in October 1853, and an incident at his residence with an escaped Thug in 1853. Sleeman's health collapsed in 1854 and he left Oudh to convalesce in the hills, with James Outram taking over the Lucknow Residency in November. In 1855, he was succeeded as General Superintendent for the Suppression of Thuggee by James Sleeman, his nephew. In November, Sleeman wrote to the Government proposing that "predatory tribes", such as the Sansees, Bouriahs, and Kanjars, be subjected to India-wide surveillance, surmising that "petty crime would be considerably diminished". With his health having failed to recover, Sleeman and his wife arrived in Calcutta in January 1856 and embarked on the East Indiaman Monarch to London on 1 February. On the recommendation of Lord Dalhousie, he was formally made Knight Commander of the Order of the Bath on 5 February. Sleeman died on 10 February off the coast of Ceylon, several days after the annexation of Oudh, and was buried at sea. In 1857, Major R. W. Bird published Dacoitee in Excelsis; or the Spoilation of Oude by the East India Company, in which he accused Sleeman of cynically serving as an instrument in Lord Dalhousie's intentions to annex Oudh. After Oudh rebelled against the Company in May, an 1854–1855 letter by Sleeman protesting the annexation was published in The Times that November. Bird publicly retracted his charges in February 1858 and Sleeman's 1849–1850 report was published later that year as A Journey Through the Kingdom of Oude, together with his correspondence regarding the annexation.

The 1959 film The Stranglers of Bombay centres around the discovery of a thuggee sect and its defeat by an officer of the East India Company. The film ends with a quote attributed to Sleeman: "If we have done nothing else for India, we have done this good thing." In the 1977 Satyajit Ray film The Chess Players, Prime Minister of Oudh Ali Naqi refers to Sleeman and his negative report, the text of which is used for some of James Outram's dialogue. In the 2014 historical fiction novel The Strangler Vine by Miranda Carter, the protagonist, a British officer, encounters Sleeman in Jubbulpore and becomes suspicious of his system for reclaiming Thugs.

Legacy
In the five years after publication, only 100 copies of Ramaseeana were sold privately, with most of its 750 print run being distributed to Company officials. At least one or two copies made their way to London where it was extensively copied for Edward Thornton's Illustrations of the History and Practices of the Thugs in 1837, while a pirated version was published in the United States in 1839 entitled History of the Thugs or Phansigars of India. In 1839, Phillip Meadows Taylor published the novel Confessions of a Thug, deriving much of his material from Sleeman's writings. Thuggee thereafter became a Victorian sensation, with Ramaseeana forming the basis for the colonial-era account of thuggee. There is a general consensus among contemporary historians against the portrayal of thuggee as a fraternity of ritual stranglers that sacrificed its victims to Kali. Scholars generally agree that Sleeman's representation, derived from his interviews with approvers, was distorted by the prejudices and misinterpretations of the time. The methodology Sleeman set out in his 1849 Report on Budhuk alias Bagree Decoits began to be used in the 1860s to extend special policing measures and penal provisions to various communities, culminating in the passage of the first Criminal Tribes Act in 1871. Sleeman developed a long-term interest in natural history and in 1828 made the first discovery of dinosaur bones on the Indian subcontinent in the Lameta Formation near Jubbulpore. The fossils were later proposed in 1877 as a new species and genus of dinosaur, Titanosaurus indicus. In his 1844 book Rambles and Recollections of an Indian Official, he described in detail a major 1829 outbreak of neurolathyrism in India. Sleeman provided six accounts in his 1849–1850 report of feral children nurtured by wolves, two he had witnessed himself, which were published separately in 1852 as An Account of Wolves Nurturing Children in Their Dens and are thought to have likely inspired the character of Mowgli in Rudyard Kipling's 1894 novel The Jungle Book. Unusually for British officers at the time, Sleeman took a passionate interest in the lives of Indian peasants and, according to Mike Dash, his detailed writings on Oudh remain the most complete source on the state of the kingdom in the early 19th century. Writing in 2011, the historian Rahul Govind described Sleeman's critique of the Company's economics as "almost unknown". The village of Sleemanabad, near Jubbulpore, was named in Sleeman's honour, and successive generations of his descendants have continued to visit the village. Sleeman had seven children, two of whom died in infancy, with the remaining five being sent to be educated in England due to the harsh Indian climate. In 1933, his grandson James L. Sleeman published the book Thug: Or a Million Murders in which he described thuggee as an "ancient religion of murder" and the Anti-Thuggee Campaign as "yet another jewel in the crown of Empire". Alongside Thug: Or a Million Murders, popular history books such as Francis Tuker's The Yellow Scarf: The Story of the Life of Thuggee Sleeman in 1961 and George Bruce's The Stranglers: The Cult of Thuggee and its Overthrow in British India in 1968 exaggerated Sleeman's role in the campaign at the expense of his contemporaries. According to historian Máire ní Fhlathúin, they presented Sleeman as a "master detective", with Feringheea often cast as the "master criminal". Kim A. Wagner describes these works as "historical fiction" verging on colonial hagiography and characterises Sleeman as an opportunist who sensationalised thuggee. He also asserts his view that Sleeman did not construct the colonial stereotype and undermine Indians' rights with the aim of expanding British authority. In her 1973 bestseller Heaven's Command: An Imperial Progress, Jan Morris described Sleeman as "a figure of Cromwellian integrity".
