The Sierra Leone Company
was the organisation involved in founding the first African American colony
through the resettlement of Nova Scotian
who had initially been settled in Nova Scotia
after the American Revolutionary War
The Sierra Leone Company was the successor to the St George's Bay Company which had made a mostly unsuccessful attempt in 1787 to establish a free settlement for the "Black Poor" of London.
Both ventures were promoted by the anti-slavery activist Granville Sharp, who published a prospectus for the proposed company in 1790 entitled Free English Territory in AFRICA. The prospectus made clear its abolitionist view and stated that several respectable gentlemen who had already subscribed had done so "not with a view of any present profit to themselves, but merely, through benevolence and public spirit, to promote a charitable measure, which may hereafter prove of great national importance to the Manufactories, and other Trading Interests of this Kingdom".
Amongst the early subscribers are many friends of Sharp involved in the Clapham Sect: Henry Thornton, William Wilberforce, Rev. Thomas Clarkson, Rev. Thomas Gisbourne, Samuel Whitbread
