Abolitionism is a movement to end slavery.

In western Europe and the Americas abolitionism was a movement to end the slave trade and set slaves free. At the behest of Dominican priest Bartolomé de las Casas who was shocked at the treatment of natives in the New World, Spain enacted the first European law abolishing colonial slavery in 1542, but weakened these laws by 1545. In the 17th century Quakers and evangelical religious groups condemned slavery as un-Christian; in the 18th century, rationalist thinkers of the Enlightenment criticized it for violating the rights of man. Though anti-slavery sentiments were widespread by the late 18th century, they had little immediate effect on the centers of slavery: the West Indies, South America, and the Southern United States. The Somersett's case in 1772 that emancipated a slave in England, helped launch the movement to abolish slavery. Pennsylvania passed An Act for the Gradual Abolition of Slavery in 1780. In Massachusetts, ratification of the constitution essentially brought an end to slavery through court cases, although there was no abolition law.

William Lloyd Garrison (December 10, 1805 – May 24, 1879) was a prominent American abolitionist, journalist, and social reformer. He is best known as the editor of the abolitionist newspaper The Liberator, and was one of the founders of the American Anti-Slavery Society, he promoted "immediate emancipation" of slaves in the United States. Garrison was also a prominent voice for the women's suffrage movement.

William Lloyd Garrison was born on December 10, 1805, in Newburyport, Massachusetts, the son of immigrants from the British colony of New Brunswick, in present-day Canada. Under the Seaman’s Protection act, Abijah Garrison, a merchant sailing pilot and master, had obtained American papers and moved his family to Newburyport in 1806. With the impact of the Congressional Embargo Act of 1807 on commercial shipping, the elder Garrison became unemployed and deserted the family in 1808. Garrison's mother, Frances Maria Lloyd, was reported to have been tall, charming and of a strong religious character. At her request, Garrison was known by his middle name, Lloyd. She died in 1823, in the town of Springfield, Massachusetts.

Frederick Douglass (born Frederick Augustus Washington Bailey, c. February 1818 – February 20, 1895) was an American social reformer, orator, writer and statesman. After escaping from slavery, he became a leader of the abolitionist movement, gaining note for his dazzling oratory and incisive antislavery writing. He stood as a living counter-example to slaveholders' arguments that slaves did not have the intellectual capacity to function as independent American citizens. Many Northerners also found it hard to believe that such a great orator had been a slave.

Douglass wrote several autobiographies, eloquently describing his experiences in slavery in his 1845 autobiography, Narrative of the Life of Frederick Douglass, an American Slave, which became influential in its support for abolition. He wrote two more autobiographies, with his last, Life and Times of Frederick Douglass, published in 1881 and covering events through and after the Civil War. After the Civil War, Douglass remained active in the United States' struggle to reach its potential as a "land of the free". Douglass actively supported women's suffrage. Without his approval he became the first African American nominated for Vice President of the United States as the running mate of Victoria Woodhull on the impracticable and small Equal Rights Party ticket. Douglass held multiple public offices.

Nathaniel "Nat" Turner (October 2, 1800 – November 11, 1831) was an American slave who led a slave rebellion in Virginia on August 21, 1831 that resulted in 60 white deaths and at least 100 black deaths, the largest number of fatalities to occur in one uprising prior to the American Civil War in the southern United States. He gathered supporters in Southampton County, Virginia. Turner was convicted, sentenced to death, and hanged. In the aftermath, the state executed 56 blacks accused of being part of Turner's slave rebellion. Two hundred blacks were also beaten and killed by white militias and mobs reacting with violence. Across Virginia and other southern states, state legislators passed new laws prohibiting education of slaves and free blacks, restricting rights of assembly and other civil rights for free blacks, and requiring white ministers to be present at black worship services.

At birth, Turner's owner recorded only his given name, Nat, although he may have had a last name within the slave community. In accordance with common practice, the whites referred to him by the last name of his owner, Benjamin Turner. This practice was continued by historians. Turner knew little about the background of his father, who was believed to have escaped from slavery when Turner was a young boy. Turner remained close to his paternal grandmother, Old Bridget, who was also enslaved by Benjamin Turner. Turner's maternal grandmother was one of the Coromantee from present day Ghana, a group known for slave revolts. She was captured in Africa at thirteen years of age and shipped to America.

Charles Follen (September 6, 1796 – January 13, 1840) was a German poet and patriot, who later moved to the United States and became the first professor of German at Harvard University, a Unitarian minister, and a radical abolitionist.

He was born Karl Theodor Christian Friedrich Follen at Romrod, in Hesse-Darmstadt, Germany, to Christoph Follen (1759–1833) and Rosine Follen (1766–1799). His father was a counselor-at-law and judge in Giessen, in Hesse-Darmstadt. His mother had retired to Romrod to avoid the French revolutionary troops that had occupied Gießen. He was the brother of August Ludwig Follen and Paul Follen, and the uncle of the biologist Karl Vogt.

He was educated at the preparatory school at Giessen, where he distinguished himself for proficiency in Greek, Latin, Hebrew, French, and Italian. At the age of seventeen, he entered the University of Giessen to study theology. In 1814 he and his brother August Ludwig went to fight in the Napoleonic Wars as Hessian volunteers; however, a few weeks after enlisting, his military career was cut short by an acute attack of typhus fever, which seemed for a time to have completely destroyed his memory. After his recovery he returned to the university and began studying law, and in 1818 was awarded a doctorate in civil and ecclesiastical law. He then established himself as Privatdocent of civil law at Giessen, studying at the same time the practice of law in his father's court. As a student, Follen joined the Giessen Burschenschaft whose members were pledged to republican ideals. Though he did not attend himself, Follen was a major organizer of the first Wartburg festival of 1817.
