William Lloyd Garrison
American journalist and abolitionist

William Lloyd Garrison was a prominent American Christian, abolitionist, journalist, suffragist, and social reformer. He is best known for his widely read antislavery newspaper The Liberator, which he founded in 1831 and published in Boston until slavery in the United States was abolished by constitutional amendment in 1865. Garrison promoted "no-governmentism" and rejected the inherent validity of the American government on the basis that its engagement in war, imperialism, and slavery made it corrupt and tyrannical. He initially opposed violence as a principle and advocated for Christian nonresistance against evil; at the outbreak of the Civil War, he abandoned his previous principles and embraced the armed struggle and the Lincoln administration. He was one of the founders of the American Anti-Slavery Society and promoted immediate and uncompensated, as opposed to gradual and compensated, emancipation of slaves in the United States.The source of Garrison's power was the Bible. From his earliest days, he read the Bible constantly and prayed constantly. It was with this fire that he started his conflagration. ... So also, a prejudice against all fixed forms of worship, against the authority of human government, against every binding of the spirit into conformity with human law, – all these things grew up in Garrison's mind out of his Bible reading.
