William Lloyd Garrison was an American abolitionist, journalist, and social reformer. He is best known for his widely read anti-slavery newspaper, The Liberator, which Garrison founded in 1831 and published in Boston until slavery in the United States was abolished by the Thirteenth 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.
