Frederick Douglass taught himself to read despite efforts to prevent slaves from becoming literate. He traded food to learn from white schoolboys and read materials like the Columbian Orator on his own. As an adult, Douglass published two abolitionist newspapers, The Liberator and The North Star, to spread awareness of the horrors of slavery. By using newspapers to share truths about slavery, Douglass helped gain respect for African Americans and showed how print media could influence public opinion on important issues.
