He won world fame when his autobiography was publicized in 1845. Two years later he bagan publishing an antislavery paper called the North Star. Douglass served as an adviser to President Abraham Lincoln during the Civil War and fought for the adoption of constitutional amendments that guaranteed voting rights and other civil liberties for blacks. Douglass provided a powerful voice for human rights during this period of American history and is still revered today for his contributions against racial injustice.
