Charles Grant (Teàrlach Grannd in Scottish Gaelic) (16 April 1746 – 31 October 1823), was a British politician influential in Indian and domestic affairs who, motivated by his evangelical Christianity, championed the causes of social reform and Christian mission, particularly in India. He served as Chairman of the British East India Company, and as a member of parliament (MP), and was an energetic member of the Clapham Sect. The "Clapham Sect" were a group of social activists who spoke out about the moral imperative to end slavery.Henry Thornton founder of the Clapham sect regarded Grant as his closest friend, after Wilberforce, and Grant had a house on Henry's estate at Battersea Rise before he moved to Russell Square.
Grant was born at Aldourie, Inverness-shire, Scotland on the same day his father, Alexander Grant, was killed fighting for the Jacobites, against the British Crown, at Culloden. However, Charles Grant himself was one of the growing number of Scots who prospered in the service of the British Empire. In 1767, Grant travelled to India to take up a military position. Over subsequent years, he rose in the ranks of the British East India Company. Initially, he became superintendent over its trade in Bengal. Then, in 1787, having first acquired a personal fortune through silk manufacturing in Malda, Lord Cornwallis the Governor-General appointed Grant as a member of the East India Company's board of trade. Grant lived a profligate lifestyle as he climbed through the ranks, but after losing two children to smallpox he underwent a religious conversion. Viewing his life, including his efforts in India, from his new evangelical Christian perspective, moulded his career for the rest of his life.
