    Frederick learned how to read and write at an early age. He also worked hard in the Baltimore Shipyards and saw how horrible slavery could be. He was beaten on several occasions,by his masters and other shipyard workers. He finally decided to escape, dressed as a sailor, and made it to the North.

In New Bedford, Massachusetts, in 1838, Frederick married Anna Murray. The couple soon met up with a black man named Nathan Johnson, who invited them to stay with him and his family. At that time, Johnson was reading Sir Walter Scott's book The Lady of the Lake. . Eager to leave his old identity behind, Frederick. changed his last name to Douglass, after a character in the book.

His first exposure to the Anti-Slavery Society was through reading the newspaper, The Liberator. He soon met William Lloyd Garrison, the newspaper' s editor and one of the leaders of the Anti-Slavery Society. Douglass gave a speech at a Society meeting, and many people were very much impressed. Douglass then went to work for the Society. And he worked for it for many years.

After a time, people began to doubt the sincerity of his stories. How could this man who spoke with such big words and such high- minded concepts have been a slave just a short time ago? To answer these charges，Douglass published his life story, Narrative of the Life of Frederick Douglass, an American Slave.

Douglass then went to England, where he made important friends in England, who helped him buy his freedom. Frederick Douglass returned to the United States in 1847 as a free man. He moved to Rochester, New York, and began publishing a newspaper, The North Star. The newspaper’s motto was this: “Right is of no sex, truth is of no color and we are all fellow citizens.”

After Lincoln's election and the outbreak of the Civil War, Douglass continued to press for the freedom of slaves and a new cause, the introduction of black soldiers into the Union Army. In 1863，both the things happened. Lincoln issued The Emanci pation Proclamation, and Congress passed a law approving black soldiers in the army.
