Douglass" voice would become increasingly prominent and he would serve to be one of the most significant participants in the abolitionist movement. In 1841 Douglass attended an Anti-Slavery Society convention where he was asked to speak. People were compelled to listen to his opinion; he left a profound impression on his audience. Immediately he was recruited as a speaker of the Anti-Slavery Society and would continue to distinguish himself as on orator throughout the North. His intelligence and incredible speaking abilities led people to question his former reputation as a slave, "the Liberator wrote that many people in the audience refused to believe his stories: How a man, only six years out of bondage, and who had never gone to school could speak with suck eloquence- with such precision of language and power of thought- they were utterly at loss to devise"2. To prove his legitimacy Douglass published his first book in 1845, Narrative of the Life of Frederick Douglass. Upon publishing the book became a bestseller, his message was expressed widely across America, Frederick's popularity and viewpoints furthermore promoted the abolitionist movement.
Douglass's abolitionist views were not only contained in America, Douglass also spread his word internationally. Since Douglass had manifested his experiences as a slave in his book and had augmented in popularity, he was afraid the Fugitive Slave Laws in America would penalize him, so Douglass travelled abroad to Great Britain. In two years Douglass would reinforce the abolitionist backing internationally, throughout Britain and Ireland. "His oratory made as great an impression in Great Britain as it had at home"3. In 1847, connections made in Britain had paid for his Freedom; Douglas was safe to return to America.
Upon returning to America, Douglas totally immersed himself into the black slavery problem and became devoted to help in any and every way.
