National Anti-Slavery Standard This link opens in a new windowPublished 1840-1870 and using the motto "Without Concealment?Without Compromise", National Anti-Slavery Standard was the official weekly newspaper of the American Anti-Slavery Society, founded in 1833 by William Lloyd Garrison and Arthur Tappan. The society sought to extend the rights of slaves across the country and implied not only suffrage rights for colored males, but also advocated suffrage for women. With perhaps the exception of William Lloyd Garrison's The Liberator, also published by the Society, the Standard was the most influential voice for abolition leading up to the Civil War.
