In 1849, the Mansfield Township was formed that was incorporated as a township municipality in 1855. It may have been named after the English town of
Mansfield in
Nottinghamshire or in honour of Sir
James Mansfield (1733-1821), Solicitor General of Canada in 1780, or
William Murray, 1st Earl of Mansfield (1705–1793). In 1863, Pontefract Township was officially established, named after an
English town in Yorkshire. On January 1, 1868, the townships were merged to form the United Township Municipality of Mansfield-et-Pontefract. In 1888, a portion of its territory separated and was incorporated as the Village Municipality of
Fort-Coulonge. In 2003, Mansfield-et-Pontefract changed its status from
united township municipality to an ordinary municipality. ==Demographics==
