Charles Grant (Teà rlach 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.
