What did Frederick Douglass do that was so important for black history?I just need to know basic outline of him and his life. And how he contribute...

On January 1, 1836, Douglass made a resolution that he would be free by the end of the year. He planned an escape. But early in April he was jailed after his plan was discovered. Two years later, while living in Baltimore and working at a shipyard, Douglass would finally realize his dream: he fled the city on September 3, 1838. Travelling by train, then steamboat, then train, he arrived in New York City the following day. Several weeks later he had settled in New Bedford, Massachusetts, living with his newlywed bride (whom he met in Baltimore and married in New York) under his new name, Frederick Douglass.

Always striving to educate himself, Douglass continued his reading. He joined various organizations in New Bedford, including a black church. He attended Abolitionists' meetings. He subscribed to William Lloyd Garrison's weekly journal, the Liberator. In 1841, he saw Garrison speak at the Bristol Anti-Slavery Society's annual meeting. Douglass was inspired by the speaker, later stating, "no face and form ever impressed me with such sentiments [the hatred of slavery] as did those of William Lloyd Garrison." Garrison, too, was impressed with Douglass, mentioning him in the Liberator. Several days later Douglass gave his speech at the Massachusetts Anti-Slavery Society's annual convention in Nantucket-- the speech described at the top of this page. Of the speech, one correspondent reported, "Flinty hearts were pierced, and cold ones melted by his eloquence." Before leaving the island, Douglass was asked to become a lecturer for the Society for three years. It was the launch of a career that would continue throughout Douglass' long life.

Despite apprehensions that the information might endanger his freedom, Douglass published his autobiography, Narrative of the Life of Frederick Douglass, an American Slave, Written By Himself. The year was 1845. Three years later, after a speaking tour of England, Ireland, and Scotland, Douglass published the first issue of the North Star, a four-page weekly, out of Rochester, New York.

Ever since he first met Garrison in 1841, the white abolitionist leader had been Douglass' mentor. But the views of Garrison and Douglass ultimately diverged. Garrison represented the radical end of the abolitionist spectrum. He denounced churches, political parties, even voting. He believed in the dissolution (break up) of the Union. He also believed that the U.S. Constitution was a pro-slavery document. After his tour of Europe and the establishment of his paper, Douglass' views began to change; he was becoming more of an independent thinker, more pragmatic. In 1851 Douglass announced at a meeting in Syracuse, New York, that he did not assume the Constitution was a pro-slavery document, and that it could even "be wielded in behalf of emancipation," especially where the federal government had exclusive jurisdiction. Douglass also did not advocate the dissolution of the Union, since it would isolate slaves in the South. This led to a bitter dispute between Garrison and Douglass that, despite the efforts of others such as Harriet Beecher Stowe to reconcile the two, would last into the Civil War.

Frederick Douglass would continue his active involvement to better the lives of African Americans. He conferred with Abraham Lincoln during the Civil War and recruited northern blacks for the Union Army. After the War he fought for the rights of women and African Americans alike.
