From Digital History:
Frederick Douglass has been called the father of the civil rights movement. He rose through determination, brilliance, and eloquence to shape the American nation. He was an abolitionist, human rights and women's rights activist, orator, author, journalist, publisher, and social reformer.
…Douglass established his own weekly abolitionist newspaper, the North Star, that became a major voice of African-American opinion. Later, through his periodical titled the Douglass Monthly, he recruited black Union soldiers for the African-American Fifty-Fourth Massachusetts Volunteers. His sons Lewis and Charles both served in this regiment and saw combat. Douglass worked to retain the hard-won advances of African-Americans. However, the progress made during Reconstruction soon eroded as the twentieth century approached. Douglass spent his last years opposing lynching and supporting the rights of women. The antislavery crusade of the early nineteenth century served as a training ground for the women's suffrage movement. Douglass actively supported the women's rights movement, yet he believed black men should receive suffrage first. Demonstrating his support for women's rights, Douglass participated in the first feminist convention at Seneca Falls in July of 1848 where he was largely responsible for passage of the motion to support female suffrage. Together with abolitionist and feminist Elizabeth Cady Stanton, Douglass signed the Declaration of Sentiments that became the movement's manifesto. His masthead of his newspaper, the North Star, once read "Right is of no Sex – Truth is of no Color." A women's rights activist to the end, Douglass died in February 1895, having just attended a Woman's Council meeting.
