The raison d’être for the “Province of Freedom”, the Sierra Leonean settlement created by Granville Sharp and the Committee for the Black Poor, centered upon the Committee’s redemptive dogma in creating a utopian society for the Black Poor of London. Sharp believed that legalities in the settlement should model “African” law, which he assumed paralleled the Anglo-Saxon frankpledge. By applying the frankpledge, the settlers would be divided into tithings (groups of ten adults) and hundredors (groups of a hundred adults). Regular meetings would be held by the tithings and hundredors to conduct administrative duties, pass legislation, and to maintain order through the pledging of oaths and using fines as punishment. However, due to the torrid climate, disease, and conflicts with the Temne, the immediate survival of the settlement required the political and legal skills of the Royal Navy’s Edward Thompson, who served as the commodore of the fleet that transported the settlers. Utilizing legal anthropological methodologies, my research uncovers the hidden legal dynamics in the attempted establishment of a utopian civic society in Sierra Leone. Although the “Province of Freedom” was short-lived, the future colonial Sierra Leonean legal system hybridized the frankpledge with subsequent military and civilian English law.
