of the Slavery and Commerce of the Human Species (1787). By now a devout Christian, he wrote work informed by that religion. He used arguments around Christianity and global economics and politics for this cause. His writing called for the abolition of slavery and immediate emancipation of all enslaved people. It argues that an enslaved person's duty is to escape from slavery, and that force should be used to prevent further enslavement. The narrative was sent to King George III, the Prince of Wales and to Edmund Burke, a leading politician. George III, along with much of the royal family, remained opposed to abolition of the slave trade. Four years later, in 1791, Cugoano published a shorter version of his book, addressed to the "Sons of Africa". In it, he expressed qualified support for the failed British efforts to establish a colony in Sierra Leone for London's "Poor Blacks" (mostly freed African-American slaves who had been relocated to London after the American Revolutionary War. Other early settlers were the Nova Scotian Settlers, that is Black Loyalists, also former American slaves, from Nova Scotia, who chose to move to Sierra Leone.) Cugoano called for the establishment of schools in Britain especially for African students. In 1791 Cugoano moved with the Cosways to 12 Queen Street in Mayfair. His last known letter, written in 1791, mentions travelling to ‘upwards of fifty places’ to promote the book and that he found that ‘complexion is a predominant prejudice’. Cugoano wished to travel to Nova Scotia to recruit settlers for the proposed free colony of African Britons in Sierra Leone but it is not known if he did so. After 1791, Cugoano disappears from the historical record and it is likely that he died in 1791 or 1792. Commemoration In November 2020, an English Heritage blue plaque honouring Cugoano was unveiled on Schomberg House in Pall Mall, London where he had lived and worked with the Cosways from 1784 to 1791.
