The Provincial Freeman
First published in 1853 in Windsor and later in Toronto and Chatham, the Provincial Freeman catered to abolitionists in British North America and the Northern United States. Its chief editor was Mary Ann Shadd, an African-American emigrant who arrived in Canada West in 1851. Guided by Shadd's commitment to anti-slavery issues, the paper advocated that "Self-reliance is the true road to independence". The Provincial Freeman championed temperance, social reform and African-American emigration to British North America, where slavery was outlawed in 1833. Well-known abolitionists such as Samuel Ringgold Ward, William P. Newman, H. Ford Douglass and Martin Delany, as well as siblings Isaac and Amelia Shadd, also lent their editorial voices to the paper during its run. Published until 1860, the paper successfully promoted Black political discourse and revealed the degree to which middle-class African-Canadian women participated in the public sphere.
