His two most memorable acts are the abolition of suttee and the suppression of the Thugs. At this distance of time it is difficult to realize the degree to which these two barbarous practices had corrupted the social system of the Hindus. European research has clearly proved that the text in the _Vedas_ adduced to authorize the immolation of widows was a wilful mistranslation. But the practice had been engrained in Hindu opinion by the authority of centuries, and had acquired the sanctity of a religious rite. The emperor Akbar is said to have prohibited it by law, but the early British rulers did not dare so far to violate the religious customs of the people. In the year 1817 no fewer than seven hundred widows are said to have been burned alive in the Bengal presidency alone. To this day the most holy spots of Hindu pilgrimage are thickly dotted with little white pillars, each commemorating a suttee. In the teeth of strenuous opposition, from both Europeans and natives, Lord William carried the regulation in council on the 4th of December 1829, by which all who abetted suttee were declared guilty of "culpable homicide." The honour of suppressing Thuggism must be shared between Lord William and Captain Sleeman. Thuggism was an abnormal excrescence upon Hinduism, in so far as the bands of secret assassins were sworn together by an oath based on the rites of the bloody goddess Kali. Between 1826 and 1835 as many as 1562 Thugs were apprehended in different parts of British India, and by the evidence of approvers the moral plague spot was gradually stamped out.
Two other historical events are connected with the administration of Lord William Bentinck. In 1833 the charter of the East India Company was renewed for twenty years, but only upon the terms that it should abandon its trade and permit Europeans to settle freely in the country. At the same time a legal or fourth member was added to the governor-general's council, who might not be a servant of the company, and a commission was appointed to revise and codify the law. Macaulay was the first legal member of council, and the first president of the law commission. In 1830 it was found necessary to take the state of Mysore under British administration, where it continued until 1881, when it was restored to native rule; and in 1834 the frantic misrule of the raja of Coorg brought on a short and sharp war. The raja was permitted to retire to Benares, and the brave and proud inhabitants of that mountainous little territory decided to place themselves under the rule of the company; so that the only annexation effected by Lord William Bentinck was "in consideration of the unanimous wish of the people."
